Distant signal - signalling equipment used to inform the driver about the aspect that the next signal is displaying, so that he can adjust train speed or stop the train before the signal. Distant signals are used in advance of entry signals to the station, except on SBL equipped lines. They are also used before Semi - automatic signals on the intermediate signal box. Distant signals are placed at least in braking distance in advance of the signal.
Light type Distant Signal
Distant signals look like normal signals, but their mast is of a grey colour. On top of the mast there is a head with one or two lights mounted in vertical line. The light can in one of the two arrangements: single yellow or green light on the top and yellow on the bottom . If distant signal only has yellow light mounted on it, that means the signal in advance can display either a stop or proceed at reduced speed aspect.
