Abstract: Indian Railways is one of the largest networks in the country. Major transportation is done by the railways in the country. Indian Railways is the fourth largest network in the world. Many people believe Railways is one of the cheapest and safest transport, but there are certain accidents occur in the railways. Out of them 60% of the accidents occur due to the failure of the track or crack formation in the track or the absence of the track in the railway line. Now, in this project we designed the prototype of to detect the railway track crack and absence of the track in the railway line by using sensors like LED(light emitting device), LDR(light dependent resistor) and components like micro controller, max232,LCD and circuits. In this project railway track cracks are detected by placing photo diode, LDR (light dependent resistor) on either side of the track which are connected to the regulator. The regulator sends the logic of either 0 or 1 to the micro controller of 8051 family. From the micro controller it sends the logic of either 0 or 1 to the LCD in which the status of the railway track will be display on the screen, the display statements will be defined in the C program. From the micro controller it sends the logic to the motor and GSM modem. From the GSM MODEM the SMS will be send to the concerned authority of the nearest station, if the track is detected with error or crack formation or absence of track.
