In the railway system, what exactly is a signal failure and why on earth do signals fail so often?

Davar Ahmed, Kingston Upon Thames UK

• In Indian Railways as in other countries signaling system operates on interlocking route relay mechanism consisting of two components,distant signal and home signal in between any two stations. Signal failure may be caused by breakdown in computer network or human error on the part of cabinmen or failure on the part of the driver to follow the signal.
