Abstract: Indian Railways is the fourth largest railway network in the world. Although there is a tremendous growth in Indian Railways, this system is still plagued by a number of problems which require immediate attention. In this paper we are considering the major problems that lead to accidents. Major problems include obstacles entry on to the track and cracks on the tracks. To overcome this have proposed a testing train which uses ultrasonic sensor with a range of 100cms and delay is 30 cm. Based on the distance between obstacle and the train, the train slows down. When the train is at a distance of 20cm we increase the delay in order to slow down the train and finally when it reaches to a distance of 15cm the train automatically stops. During summer and winter seasons the tracks may expand and contract due to which cracks may occur. The LED and photodiode setup is placed to testing train to detect cracks. Here we are using arduino microcontroller. After crack detection the testing train stops and the longitudinal and latitudinal positions are sent via SMS to GSM and GPS.
