Railway Signalling Made Easy, Part 1

You Shall Not Pass!

This is a signal. Don't worry about the fact that it's got four lamps and a bunch of other gubbins attached to it. The important thing is that big red light, which tells us that this signal is at danger. Technically, the signal would be described as displaying a red aspect.

Passing a signal at danger is very naughty and extremely dangerous, which is why incidents of drivers passing signals at danger are handled with such seriousness. While there are a very few exceptions which we'll cover later on, on the British railway network a single red light - or, in fact, any red light - conveys an absolute requirement to stop at that signal and proceed no further.

Next instalment - the other aspects. Bet you can't wait.

Wow. Thanks for the info. Never would have guessed that Red meant Stop.
