      <Abstract>The main problem is about railway track crack detection at the earliest to avoid accidents. Therefore it is essential that such problems must be communicated immediately to the concerned authorities by using GSM technology for appropriate action.&#13;
This project uses a microcontroller  family. The primary objective of this paper  is to detect the crack in the railway track and alert the nearby station through effective and highly reliable communication mode. To demonstrate this paper, two rails forming the part of the track are made using a pair of wire which is wired with a detachable jumper in between each wire/track. Removing the detachable jumper creates a fault in the respective track; otherwise it is generally shorted by the jumper wire to simulate healthy track condition.&#13;
Removing the jumpers result in driving transistors delivering a different logic to the controller. The program thereafter takes over to send an SMS through GSM modem interfaced through MAX232 level shifter IC to the microcontroller. An LCD is also interfaced with the MC to display the status of GSM and track condition. Thus the proposed model is designed to recognize the cracks in the railway tracks and provides instant information to the concerned railway authorities.</Abstract>
