Being pedantic, maybe, but the 1972 Rule Book shows 15 reasons for passing a signal at danger with authority, and time interval working was alive and well then - it's covered under the general "passing the section signal at danger because of a block failure" (now incorporated, as far as I can...

In the absence of any other guesses then, I'll have a go. In years gone by, the clearance of a subsidiary signal was considered authority to pass the main signal at danger, and was shown as such in the Rule Book. Is that what you're looking for?

Exactly that situation Paul - except that at some locations (not Picc, as far as I'm aware), the signalling design allows the signal to clear with the front of the train standing in advance of it*, the 'off' indicator being provided for the driver's benefit. Not too common nowadays - I believe...

A rear-facing 'off' indicator (which might have some form of route indication too). I'm not sure if it applies to all such indicators - I was thinking mostly of those provided for trains starting from beyond the platform starter.

That's one! The other is intended for (train) drivers, but doesn't normally face the driver that it's intended for... --- old post above --- --- new post below --- Any other offers? Perhaps it's time to offer a clue to indicate the route to the second required answer. --- old post above --- ---...

In that case (ta) - give two examples of an amber indication in a railway signalling installation.

That it's a lower speed than the 'straight' route - and that's about it, in general terms. Not sure whether it must be the highest speed diverging route, but it generally will be.

I've still got nothing, I'm afraid - will try and find something for the future though!

I've kept out of it as I've no decent photo to share - but 33056's previous photo is Manton Junction. Definitely a Midland box!

Correct on both! Second one is just 'be prepared to find the next stop signal at Danger though' - may be because the train in front is still in section, but could be because the train's not booked to go into the forward section!

No and no! Just to clarify, I'm looking at the general (and current) situation, not any local instructions at a specific location. In Nym's case, I'd expect the signal would be maintained at Danger for quite some time!

I was resisting the temptation to put everyone out of their misery ;) . Next question then: If a semaphore stop signal (let's say it's the home signal at an anonymous signal box) is maintained at Danger until an approaching train is quite or nearly at a stand at it, what two things must the...

When it's in the former Western Region???

I won't post any names as I've had to look them up - but Quail shows three crossings (one MCB outside the box and two CCTV), all supervised by Low Gates?

Had hoped for just a couple more responses at least :) . Can't pick many holes in Zoe's answers though. Just the first one - obviously the Rule Book doesn't lie, but I didn't have your second (SGI 4.13.2) and last (SGI 20) in mind; not sure whether these are a fairly recent addition to this...

I did promise to put something together a little while ago, so here goes. It's handy proof-reading of the wording of a couple of questions if nothing else :) . All questions refer to an Absolute Block in this case. 1. The Signalman at B has accepted a train under AB Reg 3.4 from box A. A...

One or two others then: Upminster - Grays, numerous OTW branches (Romford - Upminster for example), Kensington Olympia, Chesham and Mill Hill East on LUL, Walton-on-the-Naze (is that more than 50 miles from London?), Tonbridge towards Hastings (likewise?) and so on :) .

I don't think any of the above are halfway down the physical platform :) .

I'd suggest that it's entirely down to the level crossing, and the need to position the signal a certain distance in rear of that (for a stopping train, the signal will be at Danger and the barriers on the AHB still raised when the train approaches). At a guess, the platform has only been raised...

Interesting; thanks for providing that snippet. I wonder how many exceptions there are around the network?
