Repeater signals are officially yellow. Ans I agree, they would not use red for showing a gap, because then red would become an ambiguous colour - something which it can never be allowed to become. As soon as red means anything other than stop, you're asking for trouble!
As for the "shouty man", a whol generation of people grew up hearing him at Bank (Central Line). Part of urban folklore!

I could remember being in the class at Ashfield House and our trainer saying, "Repeater signals are always X, never Y or Z", but couldn't remember which was which - though I was fairly sure yellow was right.  |

Fair comments rich32. However taking your comment about users whose first language is not English, perhaps a bit of lateral thinking called for? "Mind" and "Gap" are unlikely to be meaningful to foreign language speakers. Whereas, some words are more universally identified such as "Attention" I see your point OPNR, but trust me, from experience, simple, very basic, English gets the message across much better and quicker. |

Being the resident dinosaur, as I have written before elsewhere, any servant of a railway company who refers to the "on" colour of a repeating signal as anything other than yellow should immediately be booked off sick and only allowed to return to duty upon presentation of a certificate which declares that said person has had their brain removed, thoroughly washed and replaced in the correct manner  . |

Yes it's most definitely yellow and is denoted in the railway alphabet as 'H', double yellow as found in 4 aspect signalling is believe or not 'HH'. There is simply no amber on the railway just as there are no bends! |

Whereas, some words are more universally identified such as "Attention", further if the white light bulbs were replaced with red light bulbs in the sub-platform illumination, that might inspire a more universal implication of Danger? The trouble with any red lights on a railway is that they do mean Danger - specifically, "Danger, don't drive your train past this point or else!" This is why repeater signals - the ones that can be seen on some platforms, that 'repeat' the station starter signal so that staff doing platform duties can see when the train has a signal to depart, don't have a red aspect - it's yellow. (Or amber, or orange. I can't remember which one it officially is. *g*) I assume having any red lights lying around would be a big no because of the risk of confusing drivers - either stopping the train early or subtly eroding away at the reaction of red=stop. Might work if they only came on once the train was berthed in the platform. There are probably other ways to spend lots of money though. |

Ha Ive been to one of those at Ashfield (: Okay between you lot and I, I can say Emma Clarkes has NOT been sacked despite what the media says and will still be used for London Underground DVAs hence the recent ones. This is going by an e-mail of mine from London Underground |

However when you are in a multi aspect signalling area, fog repeaters show a white aspect as opposed to a green. |

Actually, and I'm afraid this is completely off-topic... on approach to Cockfosters you have PM2 (protects the points into the platforms) and, a little way before that, all in one place, PM1, RPM2 and a Fog Repeater of PM2 (Is that FPM2? Or FRPM2? I don't know.). Question is: when PM1 is showing a red aspect, both the repeaters show no aspect at all. Is this normal and, if so, why? Is it for safety, 'just one of those things', or is there some other reason?

When PM1 clears, the other signals will show an aspect. That is the same all over the network. |
