London Bridge signals question
In article , G
writes I've seen RA indicators at Manchester Victoria, where there are no single manned trains. Are they serving the same purpose? And, while I'm in obvious (but not to me) question mode, above the signals are larger ones that occasionally display U B in two boxes. Why? They are telling the driver which route he's going to take (so he knows which speed restrictions apply and which is the next signal to obey). Normally I would suggest it's short for "Up Bolton", but Quail tells me that all directions from Man Vic are Down, and there's no Bolton line leaving the station. ["U" is normally "Up". Going "wrong road" is normally shown with an "X".] -- Clive D.W.
