Network Rail have tweeted that they plan to reopen tomorrow morning:
A mile of track, signalling equipment and the level crossing have been repaired. Good work by all concerned.
You can get a broadband connection down a telephone line these days, so multiplexing a control circuit onto the line shouldn't be difficult. Indeed, it's basically the same principle as an entryphone.It's far simpler to install a telephone circuit than it is to install a control circuit.
The issue is making it sufficiently robust to meet the requirements for a safety critical circuit.You can get a broadband connection down a telephone line these days, so multiplexing a control circuit onto the line shouldn't be difficult. Indeed, it's basically the same principle as an entryphone.
Excellent. I read on local facebook groups that 1700 concrete sleepers have had to be replaced, not sure how true it is, would that equate to a mile of track?
On the Norwich / Lowestoft / Yarmouth resig, where there are umpteen UWC's they used the GSM network for the Crossing phones, whether that's a good idea or not, time will tell !You can get a broadband connection down a telephone line these days, so multiplexing a control circuit onto the line shouldn't be difficult.

Yes. Surely a simple bit of technology could be included to disable the gate open button until the system or signaller is satisfied a call has been made. Also would help if the gate being open affected the railway signal aspect.Question - If there is a circuit between the phone at the crossing and the signaller, then there is probably a similar circuit in reverse.
Couldn't the 'gates open' button be dependant on the phone being off hook (call being made) - or better - since the signaller has now been 'disturbed' - couldn't he/she release the green button remotely.
i don't buy (in this day and age) that this can't be done reasonably effectively and at modest cost - may not be 'belt and braces 'ideal' - but means that the green button can't be pressed without the telephone being used.
If the rule is that the green button mustn't be used before the telephone has been - then interlock them so that it can't be?
Probably about as much as the normal/regular car driving test and lessons is based on motorways - very little.As a matter of interest, how much of UK HGV (or tractor) training and testing is specifically related to POGO crossings?
Yes, we should always be looking at reasonable steps to avoid risks for those around us.I must admit I find myself puzzled that members of an industry that, rightly, prides itself on it's safety record are so keen to simply blame the driver of the tractor rather than consider whether the railway could do something better to ensure that future incident are even less likely. By all means if you read all the instructions the correct way to use the crossing is clear. But by having a numbered list, which does not include the most important instruction to phone the signaller, would appear to be opening up the signs to misunderstanding. Indeed the RAIB in the Frognal Farm report went to great lengths on this subject:
Before going onto recommend:
Now in this case it may very well be that the tractor driver was intimately familiar with how the crossing is supposed to be used and didn't use it properly. But clearly it has been identified in previous incidents that the crossing signs are not as clear as they could be. Not having item one on the numbered list as "Call the signaller to check it is clear to cross" seems like a huge oversight to me. So rather than simply dismiss this incident as being a case of a driver being impatient or to stupid to be allowed on the road surely we should be thinking to ourselves that even if those are true actually it has shown up a problem with the signage which could be corrected so that the chance of an accident is further reduced?
I'd have thought the same until I realised what I'd done when I first saw the sign in question - read "Stop", then went straight to the numbered list of instructions, having assumed the remainder of the red-background text was the boilerplate warning I've already seen on red-backgrounded signs all over the network.
Thus I'm inclined to agree with the RAIB in saying that it's a weakness, regardless of the extent to which it was or wasn't involved in this incident.
The above two amplify my point that it is easy to ignore the white on red writing. We all scan read to a greater or lesser extent and identify the important bits we need. Try reading duel language road signs. In Wales it takes me an age to understand the road signs I often spend too long trying to read the Welsh language part before realising it does not make sense - that leaves me no time to read the English part. I would say it takes more than twice as long to understand a dual language sign even though you only need to read half of it. Different coloured backgrounds would help in the case of bi-lingual signs BUT my point is the use of different fonts / colours is counter productive in the cases where the whole sign should be read.Looking at it as a whole, I find that I see the large "STOP" message, and then my attention is drawn to the numbered list. I'm looking for instructions, and we're accustomed to seeing instructions in ordered lists. If you've ever used a recipe (especially online) there's a title, a blurb that waffles at great length, and then an ordered list. It's what we're used to.
What we aren't used to is the main important thing being item 0 in the list of things to do.
I agree with that - we must think outside the box. The box being our railway world.There was a thread here a few months ago about what if somebody was deaf and wanted to use one of these crossings what would happen? Food for thought..
Everybody in here has an interest in the railway so you’re looking at crossings from a different viewpoint. The average person doesn’t have these same viewpoints and I think people here forge that.
If the signaller is that busy with crossings then perhaps the signaller needs to be more than one. I find myself wondering whether closing all those crossing keeper boxes was a false economy - probably an over economy !.No I haven't that is why I said it was a question.
But - again from a point of not knowing I would ask:-
1) Should pedestrian access be via a separate small gate from the one with the green button for the cattle/vehicular access?
2) If the signaller is being telephoned regarding opening the main gates he already has to have his attention on the matter, otherwise what's the point in ringing him.
If he thinks the way is clear he could press a release button with a 30 second timer that allows the green button to open the gates.
3) Relying on the local idiot to a) read and b) use a telephone before crossing is not good enough - obviously - it risks endangering the driver and passengers, never mind the idiot.
Yes, this is a conflict of types regardless of which is thought best.I do not think I missed it: why is the gate control not locked by the signalling? Does it at least warn someone somewhere that the line is obstructed?
Based on what I have seen locally (and this crossing is not far from me), it is probably misuse but those signs are still poor. I was told years ago not to use small areas of white on red text next to black on white because many people find it difficult to read (but equally many do not) and that was only an advertising/information leafket not a safety critical sign. How can the railway not know this?
The railway ought to do whatever it can to easily/cheaply avert blame or excuse makers.Whereas I am equally puzzled that people seem so keen to find any possible avenue to blame the railway. Whatever the outcome of the investigation there is no doubt in my mind that the employer of the tractor driver should have ensured that they were fully aware of the crossing and its method of operation before allowing them out, given that this is a private road and not a public highway. Surely the crossing has been used on countless occasions in the past without an accident occurring ?
Even if, as i suspect, the tractor driver is completelt to blame surely it makes sense to reduce the isk and excuses made as much as reasonably possible.I think those are trying to remove reasons for other people to blame the railway and perhaps make it that a fool in a hurry (or whatever the phease in English law is) is less likely to miss an important instruction.
But it only has to be more robust that the current non-system.The issue is making it sufficiently robust to meet the requirements for a safety critical circuit.

This was on the Ely-peterborough line, not the Fen line.Oh nice!! So at least one stretch of the Fen line will ride nice and smoothly then.![]()

One way of making sure user worked crossings are used properly would be to change the law.
If there were more then 3 incidents of misuse by the land owner or his authorised users in x years the crossing would be closed permanently.
Warnings would be issued after the first & second incident.
If it is the only access to a field, tough, the owner’s staff should have been properly instructed & watched at work.
Genghis Khan & Judge Jefferies would have been much tougher
Unless, of course, the railway is found negligent in which case he will have a new tractor and trailer, plus compensation for the lost crop and business.Yes I know precisely where it happened.
As for penalties for the farmer; well in this instance I think he's already been penalised. He's had a trailer and it's load written off and presumably the towing vehicle has been damaged too requiring repair or replacement. None of this stuff comes cheap. He's also had one of his accesses blocked for the best part of a week which will no doubt have affected his ability to run his business as usual at what is the busiest time of year for the farming community.
One thing that strikes me about the signage is that there is no indication that the gates are not interlocked with the signalling.
With a manual gate it's pretty obvious, but with user-worked power gates it's much less so.
If it is easy to attribute all the incidents to one farm or business it would make sense to eventually remove the risk.One way of making sure user worked crossings are used properly would be to change the law.

This prompts me to think. If a tractor driver is using the same crossing repeatedly they are going to end up getting a bit lazy/complacent - getting off and on the tractor all the time. I also wonder how quickly the phone gets answered if the signaller is busy.Another point about the signage is that the last sentence on the white on red bit could be read to imply that you only need to call the signalbox if your vehicle is large or slow-moving (which is the case at automatic half barrier crossings). And unlike AHBs, the notice does not even define "large or slow moving" bin any case a subjective. Although on the open road tractors are relatively slow, and tractor/trailer combinations relatively long, they are fairly typical of the type of vehicle that might be expected to use a farm crossing.
"Always telephone" in the previous sentence is clear enough, though.Another point about the signage is that the last sentence on the white on red bit could be read to imply that you only need to call the signalbox if your vehicle is large or slow-moving (which is the case at automatic half barrier crossings).

The Frognall report was very interesting, thank you for the link.
The signage is appalling. This stuff is supposed to be as fool-proof (and therefore safe) as it possibly can be. Glaring deficiencies in the signage and unworkable assumptions of “people being briefed by authorised users” have already been pointed out by Frognall. What’s changed? Who’s asleep at the wheel?
Maybe the tractor got stuck ?. Or what happened to me was the trailers I was towing got unhitched, first I knew was when the trailers overtook me on a downhill stretch !. There was always the risk of the pin getting dislodged or damaged going over a bump - like a railway crossing. I used to check it every trip and re-affix the wire if needs be. But in my case it was a new improved safer pin - the farm ceased using that design after that. Point is driving over fields and tracks was a good way of introducing faults and a level crossing would be a bad time for the fault to rear its ugly head.May be the tractor driver did see the train "O its only a goods train they only go about 20mph they lots of time to cross"

I would like to think that signallers and train drivers have had more training and profiling. Certainly the tractor drivers I knew consisted of casual labour like me and the experienced farm hands. The casual labour drivers were predominantly English in those days made up of some who were students (like me) and the rest were unemployed, some for er various reasons.Surely the above comment could apply to signallers, engine drivers, and more or less anybody doing a job...

That - or something similar - seems much more sensible to me."Always telephone" in the previous sentence is clear enough, though.
Looking again at the signage, I wonder if part of the problem is catering for pedestrians/cyclists and vehicles/animals on one sign? Perhaps the focus should be on the latter? Something like:
"STOP
Phone signaller to check if you can cross safely.
Tell them if you need extra time to cross.
Only cross if the signaller gives permission.
Pedestrians/cyclists/riders - look both ways and cross quickly if the line is clear.
OPERATING THE GATES (1.2.3.) - make this a separate sign.....
POGO crossings have a STOP sign fitted, as well as the instructions for use. I was reading about these types of crossing this morning, having fielded a request to cross at one.@LAX54 Where was that picture taken? Someone else will surely be able to answer, but I’m not sure that STOP signs are normally provided at UWCs by Nitwit Rail. Could it be that someone else has put that up thereby causing confusion with the official signage?
