Abstract

The need for having better signaling system which ensures safety, has gained more demand after the inclusion of electronic systems like track circuits, axle counters etc., into railways. Signaling problem is more severe in India because of its huge population and most of them are relying on railways. To serve the needs of passengers, Indian railways has introduced many electronic signalling systems, but survey shows that there is still scope for improvement of the safety standards which improves reliability of railway networks. This paper presents various signalling methods which includes ETCS,GSM-R,CBTC and their standardizations that were followed in India and new ideas for further improvement of signaling is presented.
