Application of railway signals : ウィキペディア英語版 | Application of railway signals
The application of railway signals on a rail layout is determined by various factors, principally the location of points of potential conflict, as well as the speed and frequency of trains and the movements they require to make. == Non-provision of signals ==
Before discussing the application of signals, it is useful to highlight some situations where signals are ''not'' required: *Sidings generally need not be signalled, as all movements within them are made cautiously at low speed. *Tram lines frequently employ "running on sight" without any signals (similar to road traffic). *Where movement authorities are passed to drivers exclusively by means other than fixed signals, e.g. by written or verbal authority, token, or cab signalling.
