GSM based railway track crack detection using ultrasonic and infrared sensor. In this paper, we will discuss about the IoT Based System and its application in Indian Railways, as it is the problem of Indian railway system. Indain railways being one of the world’s largest railway network comprising of 115,000 km(71,000 mi) of track length over a route of 67,312km (41,826 mi) this means that if the Indian railway tracks are laid out, they would circle the earth almost 1.5 times. The recent trend that is used by the Indian railway system is manual inspection which requires much manpower and time. Our project has its main application here. The vehicle would move on the railway tracks inspecting the track and find faults if any. Our main motive is to introduce such an automated vehicle and try and reduce the human efforts, save time and provide a much precise output. In our paper, railway track sensing is done using different sensor modules mounted on the moving train.
