Smart Railcar Immobilizer and Accident Alert System

This paper is newly invented for the solution of prevention of consecutive accidents happening in Railways. The embedded project ensures a fully automated system that provides unauthorized access of trains and running away from stable rake is immobilized by the train immobilizer. This Train Immobilizer consists of three levels of security- RFID detection, Biometric Sensing and typing password. The consecutive accidents are prevented by the accident alerter that protects the accident spot in case of any train accident by sending out a RF message to 2 kilometer radius which is sensed by the approaching train and reduces the speed thus avoiding the collision between the trains. Further the speed of the approaching train is reduced automatically thus providing successive collisions. TIAA (TRAIN IMMOBILIZER AND ACCIDENT ALERTER) reduces the human dependency thus enabling a safe and secure system. With the help of GPS and GSM module, Railcar is tracked and detected for any emergency purpose.
