I don't know whether one's SOL record is kept separately somehow nowadays, but the information contained within is certainly well integrated into the CMS at our place. They are very difficult to distinguish between in that respect. I still maintain that the SOL record, as a standalone item if it can ever be considered as such, is a record of details of any SOL incidents. Taking power towards a signal cleared for a wrong route isn't an SOL incident.

Back to the 'ask a Signalman a question' theme, here's one that prompted a bit of discussion recently. A driver approaching a middle-sized station, on a service booked to work through, was surprised to find himself signalled into a terminal platform. Unbeknown to him, there was a set swap planned for some reason, so his unit would instead be stabling there. The driver would be right to challenge the route in that case - no problem so far. However, all routes through the station throat are 15mph so no approach control into the terminal platform - but the speed approaching the signal protecting the station is considerably higher, and by the time the route indicator came into view, he had a job to stop in time. He considered it a signalling irregularity of sorts, and thought that he should have been stopped beforehand and advised that the service wasn't working through (you'd think that someone would have told the guard who could have told the driver, but that's not really the point). Thoughts?
I ask this based on something I saw yesterday, which must be pretty normal at the location: what do you do, if you MUST stop a coach length back, when there is a red signal at the end of a platform that means you need to be closer to get all the train to be next to the platform?
Our PDP states, for that very scenario, down to walking pace 20m from the signal, then creep up to the required stopping point.

PDPs are pretty new. Signals have been there for years. Standards have changed in where they are being placed. This means we are in a situation where older signals are often too close to where a unit needs to stop. They cant be changed or moved. This is a high risk of a SASSPAD. I remember a SPAD where the distance from the DOO monitors to the signal was a factor and group standards were brought up. The signal has been upgraded and moved to be slightly further from the platform edge.

As Tom says. a PDP can account for that and force a Driver to drive accordingly.


By "core section", do you men's between St. Pancras and Blackfriars? Which signal/line is that on?

Leaving City for Blackfriars. Probably my least favourite set of signals on my part of the network.



I still maintain that the SOL record, as a standalone item if it can ever be considered as such, is a record of details of any SOL incidents. Taking power towards a signal cleared for a wrong route isn't an SOL incident.

Not to quote you back on yourself but...

and contains details of any SOL incidents whether you were at fault or not.

It's because of this. I also don't see it as a SOL incident but I can see an interpretation in the rulebook that could push it as competency. I really do see them as much more than what they were previously.

However, all routes through the station throat are 15mph so no approach control into the terminal platform - but the speed approaching the signal protecting the station is considerably higher, and by the time the route indicator came into view, he had a job to stop in time.

Hate to say it but that's a route knowledge issue. Any terminal station, even with through platforms, I need to allow to be stopped at any signal and go permissive. He would also have been checked down to the red. Simply by being checked down, often and indication of route, he should have been braking for the red. Sounds like he was driving to an expected sequence and not for the red.

He considered it a signalling irregularity of sorts, and thought that he should have been stopped beforehand and advised that the service wasn't working through (you'd think that someone would have told the guard who could have told the driver, but that's not really the point). Thoughts?

I agree he should have been informed. With not being able to use the GSMR whilst moving or the Signaller not being allowed to call us on the move (that new rule update weirdness) I can understand how it gets missed.

This happens quite a lot. TBH.

Tom are you a Driver now ?

Its the ones that regularly revert to red or where your continually wrong routed that are the problem.

As an aside. More and more I will just sit on a single yellow and wait til it steps up before moving. There is one in the core section where I don't think any Driver pulls away on a single yellow. We have one on our network now where they wont even dispatch on a single yellow.

And this will only get worse as more and more services are running on more and more congested lines - our ARS is a great tool but it's heavily dependant on how well it's programmed / schedules are planned. ERMTS will have the same problems, great in theory but I suspect exactly the same issues will crop up.

As signallers we are led into traps all the time with regards to wrong routes - headcodes are the primary problem (i.e every 2Exx goes this way but once in the evening peak it goes another way). Sometimes TRUST / CCF / ARS say different things and sometimes we have literally no idea where you're going and have to ring you up because nobody has thought to tell us. There are a few other subtle traps that it's very easy to fall into as well, especially if you're dealing with 100 other things etc...

Thankfully most drivers are as good as gold :D

Seems like the driver was led into a trap by the signalling - it's not a signalling irregularity (as long as the signalling is working as designed and there aren't any wrong side design faults in the system). Do you mean he struggled to stop at the signal to question the route? If so it's a difficult one, if the speed is the same regardless they'd be no need for approach control/a PRI but this makes your lives more difficult/risky as drivers in terms of wrong routes. If he'd have been wrong routed into the terminal platform and he couldn't stop in time would this be classed as the driver taking the route even though he put the anchors on? (Which would be absurd...)

Another related thought - if you're running on greens/yellows do you mind if I call you directly or do you prefer me to press the 'contact signaller' button? (for non urgent stuff).

Technically we can't call you on the move but if I need to and can justify it then I will - rightly or wrongly. Will always send you a 'contact signaller' if you're approaching a red though (not worth the risk) unless it's an emergency in which case I'll do an urgent call.

Absolutely. It's our job to allow for such routing. Every red we get is preceded by cautions. So you have to be doing 20mph 200m away. That's plenty of time to stop. Approaching a terminal platform generally comes with some kind of checking down. My home station is exactly as described. We have bays and high speed through platforms. You can tell from a few signals out where you will be routed. The bay's always check down to red at the home signal and the through platforms step up on approach. Its route knowledge that lets you know where your going into.

I speak to Trainees regularly. Most haven't been taught about checking down and route indication because you get 2 yellows. We had someone who took a wrong route because she was driving to the signals and thought she was signalled through the junction. Even the DM's said she was in the wrong because she should have known that she needed 2y on a certain signal to get to her station :/ This knowledge is being lost and trained out of us.

I think we have one (at least what I sign) route where the aproach is at linespeed and you don't get any indication till your 1 signal out. From what I know of. If you were wrong routed here and were driving for the junction speed, you would not be at fault because its a know location where you couldn't stop in time. Of course the professional in me just screams that if you knew that. Then you would come round at caution and prepare to be wrong routed just in case.

Personally, I couldn't care but I've been driving for years. With all the changes etc. 'Contact Signaller' is the best way. That way I can stop and call when I feel I can and there is no risk. I generally stop at the next signal either way.

Technically we can't call you on the move but if I need to and can justify it then I will - rightly or wrongly. Will always send you a 'contact signaller' if you're approaching a red though (not worth the risk) unless it's an emergency in which case I'll do an urgent call.

Funnily enough what used to happen and still does to an extent; is that the road would go back to red and a contact signaller message comes up. You looked over and go yes, I know. Now they leave the route set wrong and still send the contact signaller message. My normal conversation is pretty quick after that. "yes you can set the road back, thanks for letting me know' Its almost like a sorry button. When I have to challenge the route it pust me on the back foot.

Funnily enough a similar thing happened to me last week. Intermittent track circuit fault meant signal reverted from Y and J1 to red, then back up to Y and J1. Stopped short and reported it, and asked if I should pass it as if it were showing danger or accept the proceed aspect. Signaller told me to accept the aspect.

I wasn't particularly happy doing so but followed the instruction. However found out later on that a previous driver had potted the same signal due to the same track circuit fault.

Out of interest did you still drive at caution as if you had passed the red regardless of accepting the proceed aspect? (Obviously above the normal caution level when passing a single yellow)

Yes, more than likely out of habit. Thankfully the next signal is only a short distance away so even travelling at caution it didn't make too much difference to the delay.

It's because of this. I also don't see it as a SOL incident but I can see an interpretation in the rulebook that could push it as competency. I really do see them as much more than what they were previously.
I don't think there's anything in the Rule Book that they could use against you there, but I'm sure they'd have no problem finding something in the PDP or other company instructions. That's the thing, though - it'd have to be pushed as a competency issue, an area requiring development or whatever ("minor [or major] improvement required" on ours), but still surely couldn't be considered a SOL incident.

Our CMS has a separate section for "safety incident history", where a minor competence issue that's been identified on a ride out or other assessment is unlikely to appear. Maybe a wrong route incident would be shown here even if there's no blame attached, I don't know. The only incident (a passenger doing something silly with doors and slightly injuring themselves as a result) on mine is there because I reported it, it's clearly identified as something that I'm not at fault for, and my written report is the only item attached to it.

I think the big thing that's puzzled me is why any manager would go looking at downloads, seemingly trying to pin something on the driver, for a simple wrong route that the signalman is clearly responsible for and the driver correctly stopped and challenged.

Hate to say it but that's a route knowledge issue. Any terminal station, even with through platforms, I need to allow to be stopped at any signal and go permissive. He would also have been checked down to the red. Simply by being checked down, often and indication of route, he should have been braking for the red.

I think you misunderstand the situation. Whether a train is signalled into a through platform or the bay, it'll receive clear signals throughout with the normal aspect sequence up to either the signal at the end of the through platform or the buffer stops in the bay. The first route indication into the bay that the driver would've received would have been at the last signal before the station, which he'd be approaching fairly quickly having had a double yellow at the previous one and therefore certain that the route was set all the way into a platform.

(Obviously it'd be different if the route was set into an occupied platform, but it wasn't)

I agree he should have been informed. With not being able to use the GSMR whilst moving or the Signaller not being allowed to call us on the move (that new rule update weirdness) I can understand how it gets missed.

This happens quite a lot. TBH.
This is where I'm not sure. I don't think I would have done it as a signalman. The train was now planned to terminate there, not to work through, so the correct route had been offered and I'd really expect the traincrew to have been made aware of the change to the plan by their own Control. What if the train had been planned to terminate all along, and it was a diagram error that led the driver to believe that it worked through? I would never object to the driver querying it, but I certainly wouldn't consider it a signalling irregularity as the route set wasn't wrong.

Tom are you a Driver now ?
Yes, I'm afraid that I've (relatively recently) joined you on the dark side.

As signallers we are led into traps all the time with regards to wrong routes - headcodes are the primary problem (i.e every 2Exx goes this way but once in the evening peak it goes another way).
Going off on a bit of a tangent, but the TOCs' planners really don't help by failing to understand and ignoring the long-established conventions. We all knew that our 1Lxx trains were going to the former Anglia region because that's what it's always (well, nearly always at least) meant, so it doesn't help when they throw in an STP working that's running as 1Lxx (and in the same numeric range as one of the WTT workings!) to a different destination for no reason other than that the name of its destination began with 'L'...

Seems like the driver was led into a trap by the signalling - it's not a signalling irregularity (as long as the signalling is working as designed and there aren't any wrong side design faults in the system). Do you mean he struggled to stop at the signal to question the route? If so it's a difficult one, if the speed is the same regardless they'd be no need for approach control/a PRI but this makes your lives more difficult/risky as drivers in terms of wrong routes. If he'd have been wrong routed into the terminal platform and he couldn't stop in time would this be classed as the driver taking the route even though he put the anchors on? (Which would be absurd...)
Yes, he struggled to stop at the signal to question the route - that's it exactly. No need for approach control to any unoccupied platform there. I can think of plenty of other examples of similar issues at much higher speed junctions, including one which (if I'm not mistaken) is 125mph on the approach and through the junction on both routes, no approach control or other advance warning for either route, and one of the routes isn't electrified. Big potential oops there? The driver couldn't carry any responsibility there, although they might look at downloads I suppose to see whether he did absolutely everything he could to stop in time once it became apparent that a wrong route had been offered.

Absolutely. It's our job to allow for such routing. Every red we get is preceded by cautions. So you have to be doing 20mph 200m away. That's plenty of time to stop. Approaching a terminal platform generally comes with some kind of checking down. My home station is exactly as described. We have bays and high speed through platforms. You can tell from a few signals out where you will be routed. The bay's always check down to red at the home signal and the through platforms step up on approach.

Not here! (as established in my comments above by now)

I speak to Trainees regularly. Most haven't been taught about checking down and route indication because you get 2 yellows. We had someone who took a wrong route because she was driving to the signals and thought she was signalled through the junction. Even the DM's said she was in the wrong because she should have known that she needed 2y on a certain signal to get to her station :/ This knowledge is being lost and trained out of us.
That was exactly my first thought when I first found out that trainees weren't being taught anything about how approach control worked. How else would you know that a green where you should expect double yellow means that you've been wrong routed at the junction?

I think we have one (at least what I sign) route where the aproach is at linespeed and you don't get any indication till your 1 signal out. From what I know of. If you were wrong routed here and were driving for the junction speed, you would not be at fault because its a know location where you couldn't stop in time. Of course the professional in me just screams that if you knew that. Then you would come round at caution and prepare to be wrong routed just in case.
Similar to my example above, then, I suppose, albeit with a little bit more warning. The signalling sequence presented should always, by design, give you chance to get down to the right speed for the diverging route even if you were expecting the straight route, and sometimes (for medium speed divergences) holding the junction signal at yellow and the signal in rear at double yellow ("approach release from yellow") is sufficient to achieve that.
Funnily enough a similar thing happened to me last week. Intermittent track circuit fault meant signal reverted from Y and J1 to red, then back up to Y and J1. Stopped short and reported it, and asked if I should pass it as if it were showing danger or accept the proceed aspect. Signaller told me to accept the aspect.

I wasn't particularly happy doing so but followed the instruction. However found out later on that a previous driver had potted the same signal due to the same track circuit fault.
Was the signal approach released from red for the diverging route? I've heard of something like that happening at (presumably) another junction signal, during leaf-fall season where the unit wasn't reliably dropping the track circuit in rear of the signal (which was one of the conditions for the signal to clear for the diverging route). The signal only cleared when the unit came to a stand, making better contact with the rails. As soon as it started moving in response, it lost that better contact and the signal reverted to danger as a result. When it stopped, the signal cleared - and so on...

If it was clear why the signal had reverted, though, and it was unlikely to reoccur, then my instruction to the driver would simply have been (after an apology and a brief explanation!) to "obey the signal please".

If I may go on with the OT - I thought that once an approach controlled signal has cleared it will stay clear until the train is passed. Seems logical enough to me, since a train usually won't disappear.

I don't know whether more modern interlockings, SSI and that, work like that, but I'm sure that relay interlockings generally don't (at least not in my experience of working with them!). If the conditions are satisfied for the signal to clear (with the route set), it will do. If one of those conditions is then un-satisfied, it'll go back to danger. I suppose it'd cost more to make the relevant relays 'stick' (sorry, not an S&T man), and indeed would probably need extra relays, for no real benefit.

Because we still have a responsibility to drive accordingly. OTMR's are easily accessed nowadays and ours can be done remotely. In the OP's case it may have been that he reported the train movement and that gave them a reason to download the unit.

I think you misunderstand the situation.

No doubt you have more context than me.

Whether a train is signalled into a through platform or the bay, it'll receive clear signals throughout with the normal aspect sequence up to either the signal at the end of the through platform or the buffer stops in the bay.

So are you saying the sequence is 2Y 1Y Bay or 2Y 1Y R on the through platform starter ? So no matter what route the Driver is given he will always see 2Y 1Y+Route Indicator ?

The first route indication into the bay that the driver would've received would have been at the last signal before the station, which he'd be approaching fairly quickly having had a double yellow at the previous one and therefore certain that the route was set all the way into a platform.

I still disagree. May I ask the speed on the approach to the station ? If the speed through ALL the points into any of the platforms is 15mph then he should have been doing 15mph regardless.

Possibly I can see the issue where the signal with the indicator is a fair distance from the station and the points further than usual. Which means he could have been aiming for 30(approx) for the single yellow expecting to pass that into the through platform with a reduction enough to hit the points for 15mph

It sounds like an odd situation where you are signalled the same for a through route as you are for a platform. I still say that this is a route knowledge issue because you would have to allow for that. My other concern is if he has received a 2y 1y sequence and was expecting a red, then how fast was he passing the single yellow.

Is it a case where the through route will step up as you approach the single yellow ? Because if that is the case then I would say he is then driving to an expectation of route clearance. Very habitual but potentially a competency issue.

Route knowledge should determine how you approach such a signal sequence. Is this a common problem here or do other Drivers approach differently. One of the tests a Manager will do is 'would I have driven the same' If that answer was no then I think they may be justified in making an issue of it.

From your description of the approach to the station and getting the same indication for either platform I really don't believe I would drive it at any kind of speed and I'd always be braking with enough time to stop at the single yellow.

My big one with a high speed approach is 70mph onto a 20mph set of points, into a terminal platform or into a through platform, or through a 25mph set of points into a different through platform. All from the same signal. However, all indications on approach are different and they all check you down. I'm stunned you can be signalled into a bay platform from a high speed approach G-2Y-1Y-Buffers. It sounds like an accident waiting to happen.

That was exactly my first thought when I first found out that trainees weren't being taught anything about how approach control worked. How else would you know that a green where you should expect double yellow means that you've been wrong routed at the junction?

Not great isn't it :( As I say we are learning the signals from very different perspectives. Signals behave differently from what we are taught. Even the rule book says nothing about 2y as route indication.


On topic, I did find in the rule book where it states that if you receive a wrong route you must stop and contact the Signaller. I think if you stopped, then drew forward it becomes a a little grey.

If you stopped then you knew what the indication was showing, why then pull forward ? If I was a Manager then that would be something I asked. It would also trigger me to download the OTMR for a more accurate picture of what happened.

Who reported what ? Did the Driver report pulling forward after stopping or did the Signaller report the Driver for moving their unit. The rule says stop, report. Not stop, move, stop, report. Its a strange one but I would simply chalk it up as a learning experience.


Welcome to you new life. :)

Part of the route knowledge I'm being taught is where to expect the first of two yellows for a given route during the check down and that if the signal in question is showing green, slow down to a two yellows speed anyway and pay particular attention to the subsequent lunar.

There are some locations where the signal sections are rather short and it is sensible to drive quite a bit slower than the PSR, especially if one is expecting a diverging route.

I speak to Trainees regularly. Most haven't been taught about checking down and route indication because you get 2 yellows.

Not only are they not taught about it, they are actively lied to and flatly told that approach control doesn't exist. Being lied to about this issue was the point on my rules course where I realised it was being taught simply to tick a box rather than to actually create knowledgeable railwaymen.*

I get the point they're making - don't drive towards any red signal expecting it to come off - but why not credit people with enough intelligence to understand this, but also be aware of approach controlled signals as a concept.

*I reckon I learned more about signalling from a friendly NR signalman (I shall not name the location - absolute block box) who let me and another trainee into his box for a chat, a cup of tea and the chance to signal a few trains (under his close direction), than I did from my rules course.

Wouldn't the industry work better if both drivers and signallers were taught a bit more about each others' jobs during their respective training programmes!? That'll never happen, of course, due to cost and lack of initiative on behalf of training departments.

Needless to say this visit was arranged through a contact rather than through the training department of my TOC.

EDIT: my TOC used to include a visit to a ROC as part of the training, but this was cancelled for my course because our (very old school) trainer said he didn't see the point of watching people in a ROC "playing space invaders". Says it all, really, about the attitude the railway industry has to training, in some quarters at least.

I guess the logic behind that is: would a driver -who knows nothing about approach control- have a SPAD because he failed to prepare to stop at a signal that he thought was going to clear on approach? The answer is no, and probably that's all that matters to those that have to decide what to teach to trainees.

Whilst I agree with that logic and understand why its been removed from teaching it does create other issues. Stopping at the Red is very much the priority.

Firstly and on topic, it creates wrong route information. Getting a 2y indication IS an indication of route and the Driver then must drive for the route ahead. We have had a few wrong routes because that information hasn't been passed to the Trainee.

Secondly it creates a lack of understanding and that often brings frustration. So many Driver will complain about always getting a red at X. That frustration and lack of understanding affects the way you drive.

It creates delays. We drive so defensively now that at the 2y indication you start to bring your unit down. Yes that the purpose of Approach Control but it doesn't appear to be timetabled for and you can often be late because of the signalling indications. Especially where the newer Drivers are very defensive. We had one where it got so bad they had to issue a notice explaining the restricted overlap at the station.

It contributes to unconscious competency. If you approach a signal on a daily basis and it clears at exactly the same point over and over again, you begin to accept it. When you were told specifically to prepare to stop for the red as BB and your good self state you would understand the system now you generate unconscious competency because it becomes habitual. I know some where I can count the seconds where the red clears :/

I think the issue with training is that as the generation passes the information gets lost.

I still drive to my PDP and drive defensively but knowing what the system is doing makes my life easier and stops my frustration at various places where I get checked down.

I'm sure that's true. However that same driver will also cause delays by refusing to move towards an approach controlled signal when requested to. I'm fully aware that approach controlled signals exist and I know where quite a few are located. Having this knowledge doesn't mean I treat them differently to any other kind of signal (in any case, if I'm caught doing more than 20mph over the AWS magnet towards a red on a download, I'll be given a talking to about it, approach controlled or not).

I think unfortuntely the railway has a tendancy to infantalise its employees and assume they are all stupid. The rules course was extremely restricted in scope. The minute you asked a (relevant) question that wasn't answered on the slide being presented the trainer would refuse to answer or say "you don't need to know". I realise they need to keep the course on topic, but often I suspected they took this approach to cover gaps in their own knowledge.

Anecdotally it seems that, in comparison to drivers, signallers are treated far more like grown-ups and are trusted to use their discretion a lot more.

Another related thought - if you're running on greens/yellows do you mind if I call you directly or do you prefer me to press the 'contact signaller' button? (for non urgent stuff).

Technically we can't call you on the move but if I need to and can justify it then I will - rightly or wrongly. Will always send you a 'contact signaller' if you're approaching a red though (not worth the risk) unless it's an emergency in which case I'll do an urgent call.

Interesting question.

I respect ComUtorR's answer - but he has donkey's years on me :lol:.

As a relatively new driver I'd rather you used "contact signaller" if not urgent. If I get a call I tend to wait until I have stopped until I answer unless I'm running on greens in a long gap between stops (rare for me given the intensive metro nature of my work - I stop about every two minutes).

Signallers tend to be pretty sensible about this in my experience and tend to use "contact signaller" unless they know I'm at a station or stopped at a red.

Because we still have a responsibility to drive accordingly. OTMR's are easily accessed nowadays and ours can be done remotely. In the OP's case it may have been that he reported the train movement and that gave them a reason to download the unit.
I'm sure that makes a difference (ours can't be downloaded remotely), but I still find it incredible that they'd do that when there's been absolutely no suggestion of wrongdoing on the driver's part.



So are you saying the sequence is 2Y 1Y Bay or 2Y 1Y R on the through platform starter ? So no matter what route the Driver is given he will always see 2Y 1Y+Route Indicator ?
Yes, unless he's going into an occupied platform or being held outside for another movement of course.

I still disagree. May I ask the speed on the approach to the station ? If the speed through ALL the points into any of the platforms is 15mph then he should have been doing 15mph regardless.
Certainly! I'm not sure which line he was approaching on, but on the Down Fast it's 80mph until around a quarter of a mile from the last signal before the station, reducing to 50mph until a little way past that signal, then 25mph (all lines) and finally 15mph (all lines) shortly before the platform ends.

Possibly I can see the issue where the signal with the indicator is a fair distance from the station and the points further than usual. Which means he could have been aiming for 30(approx) for the single yellow expecting to pass that into the through platform with a reduction enough to hit the points for 15mph
The signal with the route indicator is quite a way out. He'd have been braking for the 25mph speed just beyond the signal, and would (as above) need to be down to 15mph before the platform ends whether going into the bay or into a through platform. There's no need to worry about either the buffer stops or the signal at the end of the through platform at that point - there's still loads of room in either case.

It sounds like an odd situation where you are signalled the same for a through route as you are for a platform. I still say that this is a route knowledge issue because you would have to allow for that. My other concern is if he has received a 2y 1y sequence and was expecting a red, then how fast was he passing the single yellow.

Is it a case where the through route will step up as you approach the single yellow ? Because if that is the case then I would say he is then driving to an expectation of route clearance. Very habitual but potentially a competency issue.
Unusual, maybe. There's no (signalling design) need for anything different, though. At other locations, where the route into the bay *is* approach controlled, it'll be because either there's a lower speed divergence into the bay or a much shorter distance, maybe insufficient, from the signal to the buffer stops.

Route knowledge should determine how you approach such a signal sequence. Is this a common problem here or do other Drivers approach differently. One of the tests a Manager will do is 'would I have driven the same' If that answer was no then I think they may be justified in making an issue of it.
I don't think it's a common problem, mostly because it's uncommon for trains to be wrong-routed there (and indeed this one wasn't actually being wrong-routed). I don't see why anyone would or should expect to have approached the station any differently though.

From your description of the approach to the station and getting the same indication for either platform I really don't believe I would drive it at any kind of speed and I'd always be braking with enough time to stop at the single yellow.
But, given the relatively high speeds both on the approach and through some of the pointwork, there's a risk of picking up delays. Who would the delays then stick to?

My big one with a high speed approach is 70mph onto a 20mph set of points, into a terminal platform or into a through platform, or through a 25mph set of points into a different through platform. All from the same signal. However, all indications on approach are different and they all check you down. I'm stunned you can be signalled into a bay platform from a high speed approach G-2Y-1Y-Buffers. It sounds like an accident waiting to happen.
Is there a through route that's much higher speed than the others, with no approach control? In this case, everything's down to 15mph running into the station (and this is a fairly recent installation too, pretty much from scratch in the last five years), so I'd say that the risk is minimal.



On topic, I did find in the rule book where it states that if you receive a wrong route you must stop and contact the Signaller. I think if you stopped, then drew forward it becomes a a little grey.
Maybe you could argue something along those lines. It seems an odd thing to pull someone up on, though. The signal's still cleared, albeit for a wrong route, so there's really no risk in drawing up to the signal after stopping short for whatever reason. What if (okay, pre-GSMR) there's a station some way in rear of a junction signal, from where you can clearly see that a wrong route has been set but have no way of contacting the box?

If you stopped then you knew what the indication was showing, why then pull forward ? If I was a Manager then that would be something I asked. It would also trigger me to download the OTMR for a more accurate picture of what happened.

Who reported what ? Did the Driver report pulling forward after stopping or did the Signaller report the Driver for moving their unit. The rule says stop, report. Not stop, move, stop, report. Its a strange one but I would simply chalk it up as a learning experience.
It does seem a little bizarre, I must admit. Why stop short of the signal, unless it's whacking the brake to emergency if approaching a little quickly? Having stopped short, because a wrong route has been set, why then draw forward to it? If you can't clearly see that a wrong route has been set from there, then you wouldn't have stopped in the first place, surely?

Welcome to you new life. :)
Ta!

Anecdotally it seems that, in comparison to drivers, signallers are treated far more like grown-ups and are trusted to use their discretion a lot more.
Yes! Very much so, in my personal experience. As a Signalman, I was pretty much left to get on with it and make my own decisions. There was still a thorough continual assessment process, with my manager carrying out regular box visits and all that. We were trusted to use our discretion in different ways, maybe 'push' a train (offering it early to the next box) by a couple of minutes, work with COSSs to tweak line blockage limits even where everything was meant to be pre-planned and inflexible, be a little brave in making our own regulating decisions even when that might mean a train running early. They weren't really bothered if we used mobile phones for personal calls on the operating floor if we needed to, as long as we were sensible and didn't let it distract us (i.e. choosing a quiet moment!). The same applied to visitors, official and otherwise, really. If something did go a little bit wrong, especially if the only consequence was a slight delay, we wouldn't be beaten up too much about it. Even more serious stuff, which thankfully I didn't experience personally, it all seemed to be sorted much quicker and without what almost seems a culture of fear in the TOC world.

Whilst I'm only looking on with a bit of general interest, and Tomnick has given a detailed explanation of the particular circumstances, I'm interested as to why you seem to be a bit unclear about this. I guess it seems to me that the location is just another place where you can be wrong routed without any advance warning, with the fact that the wrong route is into a terminal platform being incidental, since the line speeds involved don't make this risky. There must be other places where you can be put into a terminal platform with the same signal sequence as a through platform and there are certainly plenty of places where more than one route has the same signal sequence on approach. An obvious example, which certainly needs your route knowledge to be good, is a terminal station with platforms of different lengths; that's in addition to all the junctions with the same (or similar) speed to more than one route.

The OTMR can make an unclear situation much much clearer. It can exonerate you if you have done nothing wrong. Therefore it is just a tool to see what happened. Nothing more, nothing less.

Yes, unless he's going into an occupied platform or being held outside for another movement of course.

Cheers. I've got a final answer for you then :)

The need to worry is the potential for a wrong route <D


Unusual, maybe. There's no (signalling design) need for anything different, though.

Its a case of two different perspectives. From a signalling design one there is no issue. From a driving one there is a need.

I don't think it's a common problem, mostly because it's uncommon for trains to be wrong-routed there (and indeed this one wasn't actually being wrong-routed). I don't see why anyone would or should expect to have approached the station any differently though.

Its because there is a potential wrong route that you approach differently. I have no expectation for me to be wrong routed and I expect everything to go right. However, I must act professionally and I must be aware of potential risk. I'm on the same page for the sequence and the driving expectation now thanks to your added clarity but I had the same situation tonight...

3 Aspects
40mph, 60mph, 20mph diverging route in both directions.

As you say there is no need for the sequence to show anything different and my visual approach will always be Green, Single Yellow+ Route Indicator

Therefore I am in the same situation as you describe. I could absolutely hold my speed and brake exactly the same for both directions but one means I can't get back to the depot as I need the lunars to get me over. Do I (A) brake normally or (B) come round a little defensive and target fix the junction signal first ? Tonight, as always, I came round defensive, checked my junction then pulled it back to a decent speed once I confirmed the aspect and route. (B) is the more professional way.

Hate to say it but I see it as a route knowledge issue. I very much doubt the Driver will approach that signal the same way again.

But, given the relatively high speeds both on the approach and through some of the pointwork, there's a risk of picking up delays. Who would the delays then stick to?

You would have to ask the attribution guys. I believe it goes to Network Rail as the signals caused a delay. It also comes back to what I said earlier. Is this type of thing accounted for in the planning rules. Is approach control etc accounted for ? Potentially if it is then is the PDP causing the delay and the Drivers too defensive ? Attribution must have a hell of a time.


What if (okay, pre-GSMR) there's a station some way in rear of a junction signal, from where you can clearly see that a wrong route has been set but have no way of contacting the box?

Tricky barsteward ! I guess if its not considered the platform starter then you would have to pull down. If you have no contact then you are going to need the SPT. In that situation I see less of an issue as you are also dealing with a CSR problem (out of contact) I would however think about my route knowledge and use an alternative phone or decide if moving would trip a spider or not.

It does seem a little bizarre, I must admit. Why stop short of the signal, unless it's whacking the brake to emergency if approaching a little quickly? Having stopped short, because a wrong route has been set, why then draw forward to it? If you can't clearly see that a wrong route has been set from there, then you wouldn't have stopped in the first place, surely?


I think that's the crux of the matter. It seems odd and my spider sense is tingling and think there is more to the story. If I was a DM then I would download to see what happened. When I'm wrong routed I try and stop at the signal rather than hit the anchors and then need to pull down.

I'm interested as to why you seem to be a bit unclear about this.

Because the railway isn't the same everywhere and there are various exceptions to everything and standards have changed so much over the years that new installations differ greatly. Tom is also an ex Signaller so knows what can and can't happen as well as what does and doesn't happen. As BB and I state; this stuff isn't taught and isn't in the rulebook.

I guess it seems to me that the location is just another place where you can be wrong routed without any advance warning,

Which I totally understand. We have them too.

There must be other places where you can be put into a terminal platform with the same signal sequence as a through platform and there are certainly plenty of places where more than one route has the same signal sequence on approach.

Not really. No doubt there are many many places but almost everything I drive has a different indication on approach. The whole 'checking down' is common across the network. We also have PRI's nowadays which help mitigate against a slow approach to a diverging route because of this exact scenario. We have new 3 stage banners that help too.

I checked the standards a while back for route indications (different reasons) and they say that a Driver needs to see an indication for route that makes sense. having a signal with multiple route all of the same speed isn't that common and having a signal with the same sequence for multiple routes can be confusing. The risk is being wrong routed.

An obvious example, which certainly needs your route knowledge to be good, is a terminal station with platforms of different lengths; that's in addition to all the junctions with the same (or similar) speed to more than one route.

Yes very true. Hence the need to drive accordingly <D

A different scenario, then. This time, approaching Colton Junction (south of York) on the Up, which I've already referred to albeit not by name. Well off my patch, but quite well known in signalling circles at least. There's another example much closer to home, but not quite as extreme. Both routes through the junction at Colton are 125mph. There was (not sure whether it's changed now, perhaps with a newfangled preliminary route indicator) no advance warning of the route set. The aspect sequence was the same for each of the two routes - greens all the way. There's the additional risk of an electric train running off the wires if wrong routed. How can a driver manage this wrong route risk?!

I think the point that I'm working up to is that, in my view at least, it's reasonable to expect a driver to identify a wrong route set if the clues are there on the approach, or if the permissible speed on the approach is sufficiently low to enable a train travelling at that speed when the route indication comes into view to stop at the junction signal. I think, on the other hand, that it's not reasonable for the driver to do so in any other case, as relatively unusual as that'd be, nor should the driver carry any of the blame - and indeed that view seems to be reflected in how delays so arising are attributed (50/50 if the wrong route is taken and there was advance warning of the wrong route, 100% on the signalman otherwise).

Interesting stuff. Approach control should be accounted for in the planning rules. What isn't accounted for is a driver approaching a signal more slowly than the signalling is designed for, just in case a wrong route has been set. It can't be easy for the attribution folk, certainly. Who takes the delay if the driver (reasonably) stops to question the route? The driver's done nothing wrong, but then neither has the signalman.

A spider?

Looking at it from a signalman's point of view, I just don't recognise the risk associated with the movement towards a signal that a wrong route has been set from. There would (depending on the location in question, of course!) be no problem with drawing forward from the station stop to a signal at danger. This is certainly no worse than a signal at danger - there's a route set from it, even if it's the wrong route, so no immediate risk from slipping past it. Obviously I understand that it'd make life more difficult in the medium term, that it'd shift some blame for the incident onto the driver and that there are risks associated with setting back behind the signal. It just seems that there's nothing wrong with approaching the signal, even if it's as cautiously as you'd approach a signal at danger.

I think that's the crux of the matter. It seems odd and my spider sense is tingling and think there is more to the story. If I was a DM then I would download to see what happened. When I'm wrong routed I try and stop at the signal rather than hit the anchors and then need to pull down.
Indeed, I'm sure there was a little more to it!

That's an interesting one. I'd assume the TOC, in the event the correct route is set.

Thankfully I've yet to be wrong routed. I've stopped to query unusual routes a couple of times (one location in particular where the route I had been given would require me to be crossed back across at a later junction which is very rarely used). Indeed on one occasion the signaller thanked me for checking!

If I got a delay report request through I'd have absolutely no qualms about explaining what I'd done.

Agreed on that much. Incidentally, does your shiny remote-access OTMR flag up when an emergency brake application is made? That might have been enough to justify a closer look, I suppose.

It is alleged too. (but not the OTMR) I've heard mixed messages from both Managers and Drivers. I do know for 100% certainty that they were specifically checking every single unit on a daily basis if they had an emergency brake application. The OTMR is the basic data recorder but we also have XDM (remind you of anyone...) Which is like the OTMR but much much more. That flags up pretty much everything and that is supposed to send messages back to the server and they get a system message about any emergency brake application. It is also supposed to flag up if a unit goes over its max speed too. Our shiny XDM system can also be accessed remotely and they have an interface where they can see exactly what a Driver is doing in real time. Tracks its location too :/

I think the point that I'm working up to is that, in my view at least, it's reasonable to expect a driver to identify a wrong route set if the clues are there on the approach, or if the permissible speed on the approach is sufficiently low to enable a train travelling at that speed when the route indication comes into view to stop at the junction signal.

I agree. As I mentioned earlier, we do have places where you are stuck and may not be able to stop in time for a wrong route. I haven't heard of any Driver on our patch being penalised for such a situation. I think as we get more and more PRI's introduced and the signalling standards change over time there will be less and less of such places existing. Annoyingly the PRI's we have feel pointless. They are at locations where you are checked down ! I know they speed up the approach on restrictive but I certainly see a benefit of where your new scenario could seriously benefit from a PRI.


Who takes the delay if the driver (reasonably) stops to question the route? The driver's done nothing wrong, but then neither has the signalman.

Been there that's for sure. I'd also love to know :)

A spider?

Track Circuit Spider. The spider like wiry thing in the track. If you know you need to trip the spider before the route will time out and step up then us old school folk tended to deliberately trip the spider. Knowing how close you need to be to a signal is another lost bit of knowledge. All the newbies stop 1 coach length away. We had one infamous signal where it happened all the time. You needed to get bloody close and some Drivers refused to take power. Others, like me, knew where to stop.

Looking at it from a signalman's point of view, I just don't recognise the risk associated with the movement towards a signal that a wrong route has been set from.

Now you have seen the training and how risk is treated from both sides you will probably change you mind as you develop your driving career. Every single movement towards a signal is looked at as being a risk. Drawing forward on a red particularly so. Wail till leaf-fall and the Signaller stops you on a red just to tell you its slippery !! ! !! ! ! ! Leaf fall is also a time where you tend to stop further back and it causes such issues where you may be asked to draw forwards. Not something I do lightly in the leaf-fall.

A brave new world indeed! That's progress, I suppose. I do think that it's a slightly worrying move, albeit maybe only a small one, away from OTMR's primary purposes thus far, to support investigation post-incident and to form a part of the competence management regime, and towards just spying on drivers' every move. Still, I already work on the basis that my every move is being intently watched...

Agreed. A PRI would certainly greatly reduce the probability of a wrong route being taken, and the risk arising (largely indirectly) as a result. Everyone benefits from that. It does shift a chunk of the responsibility onto the driver if a wrong route is still taken though!

Been there that's for sure. I'd also love to know :)
I read through a few such delay incidents on TRUST when I was still in the box, and the inevitable disputes made for interesting reading. Generally, I think they tried to stick it to the driver. In those cases, though, it was perhaps slightly harder to argue that the driver was justified in querying the route (not that, as a signalman, I'd ever object of course). Ultimately, though, it has to be stuck somewhere and I doubt that anyone would lose too much sleep over it.

You needed to get bloody close and some Drivers refused to take power. Others, like me, knew where to stop.
A new one on me! I've certainly never come across anywhere where you'd need to get that close to the signal to drop the track circuit in rear of that signal. The track circuit controlling the approach release has always been much longer, anywhere that I've seen it, with a timer if necessary to delay the clearance of the signal. The ones that I've heard about causing problems are where drivers have stopped a really, really long way back, or where the train has to be clear of another track circuit further in rear to prove that it's short enough to fit into wherever it's been signalled. Maybe it's something unique to the Southern Region's tramways (where, in fairness, I know everything's a lot more congested!) ;) .



Now you have seen the training and how risk is treated from both sides you will probably change you mind as you develop your driving career. Every single movement towards a signal is looked at as being a risk. Drawing forward on a red particularly so. Wail till leaf-fall and the Signaller stops you on a red just to tell you its slippery !! ! !! ! ! ! Leaf fall is also a time where you tend to stop further back and it causes such issues where you may be asked to draw forwards. Not something I do lightly in the leaf-fall.
Agreed again, definitely. I've been there, cautioning drivers for low rail adhesion. The first one had a bit of a scare when he put the brake in for my distant, but managed to stop well short (with a tunnel in between!) and declined to move any further until it came off. There wasn't any need to move any closer, though, so he just sat back there for a while. The second driver told me that he'd had a load of problems stopping at the signal in rear when I held him there to be cautioned (and subsequently had a nice three mile slide in the section). Thankfully, going back yet another signal to caution the third train, all was relatively well after that!

Leaf-fall aside, though, I certainly wouldn't consider the risk associated with drawing up to a signal from which a wrong route has been set to be comparable to the risk associated with drawing up to a signal at danger, though?

If you are stopped, brake 3, neutral. There is pretty much ZERO risk of anything happening. The train isn't moving. The Signaller can rest the route and you can deal with the passengers. Job done. The second you release the brake you are introducing risk, and for no reason. I don't think they see it as Red/Not red. Its more to do with train movements that don't need to happen.

Release the brake, roll backwards.
Take power, wrong power notch and the unit dives forward.
Take power and creep forward, drift past the signal.
Release brake, draw forward, stop again... Passcomm

Etc etc.

It's also a generic rule for all traction types. I sign 4 different units and they are all pretty modern. One is a pain in the ass to pull forward (even when coupling up) Its a jumpy bugger. I also don't see a problem but I must accept and allow for the risk.

Over the last few years the rulebook has changed. One of the reasons why is because not all rules can be applied to all traction and not all rules can be applied to all regions. Give us a generic rulebook for everyone and then PDP, local instructions and TOC appendix rule books apply the rest. The rule I checked simply said, stop and contact the Signaller. The rest is all policy and procedures.

I think that's probably getting close to the core of the issue here. If you've stopped because a wrong route has been set, don't move until it's sorted unless there's a good reason to (and I have to say that our lot seem to take a pretty sensible approach to that sort of thing, as long as you can justify what you've done even if it does slightly deviate from the highly prescriptive PDP).

Was the signal approach released from red for the diverging route? I've heard of something like that happening at (presumably) another junction signal, during leaf-fall season where the unit wasn't reliably dropping the track circuit in rear of the signal (which was one of the conditions for the signal to clear for the diverging route). The signal only cleared when the unit came to a stand, making better contact with the rails. As soon as it started moving in response, it lost that better contact and the signal reverted to danger as a result. When it stopped, the signal cleared - and so on...

Only just got around to replying to this, apologies for that.

It is the last signal in a sequence of flashing yellows, plus that section is straight for a good few miles so you can see if the correct route has been set up or not. Leaving the previous station the signal was at red, which I've only seen a handful of times when I've been following something very closely or when there has been a track circuit fault, so I knew something was up straightaway. However the normal sequence then started so thought the train in front must have been delayed. Sure enough track circuit fault when it dropped back to red approaching it.
