Signalling question

[cambsy]

Could a signal show amber aspect but be giving clear on a.w.s?if this happen does the driver work to what aspect show or what a.w.s tell him,and should driver emergency brake if see aspect at amber when a.w.s tells it s clear ahead,

The colour is yellow not amber. The AWS willl give a warning horn for a yellow signal. If the AWS sounds the bell at a restrictive aspect then it is a wrong side failure and must be reported immediately to the signalman.

Would not apply emergency brake but would stop at next signal regardless of aspect and report it. Along with filling out a 3185 form with the details

As the Drivers have stated, it is a 'wrong side failure' and must be reported immediately. it is treated as so serious because it gives a clear indication (or no indication unless it has changed) when a warning indication should be given. Just like when a signal shows a proceed aspect (not a subsidiary aspect) with a train standing ahead of it in the next signal section, or when a track circuit shows 'clear' with a train standing on it.

By the way, the only place you will find an Amber light connected with railways is at certain level crossings to comply with road traffic laws.

Always react/work to what the signal is displaying.

Unless it is a semaphore distant showing clear and AWS horn sounds in which case you treat the signal as being at caution

I guess the general rule would be to work to whichever gives the most restrictive aspect in such a case? At least, logically, as an outsider, this is what makes most sense.

In a situation opposite of what the OP stated, if AWS have a warning and the aspect was clear at the point of passing over (I am aware in some cases, the ramp will probably be passed with the signal it represents out of view) then would this be a stop ASAP and report job or report later? Would it also be a right side failure or not?

Yes this is right side failure and is reported at first convenient opportunity rather than immediately

And at the back of platform starters where the train is sitting in advance?

Some signals may have stencil indicators (OFF/SDG etc) on the back of the head to aid the driver of a train when the cab is ahead of the signal. Some of these may have an amber hue to them, St Pancras before it was rebuilt was a good example. There isn't an aspect shown on the back of the signal (no doubt there may be an exception to this but not that I'm aware of ).

Indeed, I seem to remember someone confirming that they are amber rather than yellow. From looking at them, they certainly seem to be "browner" As shown here and here

Certainly the ones at Dundee repeat the theater indicator, off, and three others that never seem to be illuminated.
