Signaling systems in the Railway network, designed to convey information to drivers in order to control train movement, has evolved over several decades. Railways use different signaling schemes with different types of signals placed at different locations so as to enable train movement in a safe manner. It is possible that station tracks are occupied and it is critical that train stops rather than moves on the station and causes collision. It is also appropriate to point out that the trains do not stop at most stations and the stations are largely supposed to be in a run-through situation. However, the signaling schemes play an important role in determining the actions of a train driver in terms of slowing down the trains. This slowing down, when not required, has a significant impact on the run time of the train and also on the throughput of the railway system. The station is approximately one hundred meters and the approach to the station (where slowing up of trains could start referring to station area) is about 3 km. On the other hand, mostly inter-station is about 7-10 km on a trunk and 10-12 km on a subsidiary route. Therefore, the movement of the trains in between the stations and in stations is critical to the run time of the trains andtherefore, the throughput (number of trains that can pass in the track section in a day) of the trains . In section 2 we examine the Railway Signaling System. Section 3 deals with the problems associated with the present system of block working, signaling system construction and maintenance. Section 4 summaries the research done on railway signaling. We propose a system of railway signaling in section 5 using Wireless Sensor Network which can enhance line capacity by 3 to 4 times, increases accuracy without sacrificing safety. Section 6 concludes the paper.
