Performance Improvement of Indian Railway Signaling: Recent Advances and Development

Abstract

The cab signaling is inevitable for fast trains. And search towards cab signaling is about for more than a century. This chapter is about wireless cab signaling which is economic and reliable.

The current method of signalling in Indian railways is through traditional land post light signals controlled from the station, and the light signals regulate train operation. It is often difficult to drive the train at a steady pace due to poor visibility caused by climatic conditions [mist and heavy rain], fast blind turns, up and downs, and blinding sunshine, and it is necessary to apply brakes, which causes pain and wastes energy and time. We can provide cab signals to the loco pilot instantly to improve the output of the train service without any interruption due to the above cause. With the aid of traditional land post light signal control, I present a method for providing cab light signal by electromagnetic waves (EMW). To improve the efficiency of the Indian railway signalling system, the proposed system is a preliminary implementation of cab signalling that is linked and combined with the existing automatic block signalling system.
