Safety in railways is a crucial aspect of rail operation management all over the world. Malfunctioning of railway systems at level crossings results in accidents and usually get media coverage even when the railways is not at fault, therefore damages the image of railways among the uninformed public. Currently Global Positioning Satellite (GPS) communication system is the most advanced technique to locate the presence of different means of transport and is also very useful in detection of trains as well. The advantage of using GPS for train control functions is that it is more economical. However, the system does have some shortcomings, the most significant of which is that for certain applications it contributes error certainly excessive for locating trains in relation to level crossings. Considerably more accurate navigational information is desirable at minimal cost. For that purpose authors have proposed a train detection system based on the measurement of acoustic signal produced due to the interaction of train wheels with the rails of track. This paper is aimed to provide a comparison between both the techniques and a solution for railways to make level crossings more safe and reliable by detecting train well before in time.
