RF Based Trains Accident Security

To Prevent Accidents for trains using a smart vehicle. It is necessary to have an intelligent system which identifies the accident before it happens and informs a driver to be alert or to regulate the speed of the vehicle.  The present paper addresses the topic of fault location in railway networks. The Smart vehicle is said to be moved in front of the train. The Smart vehicle will have sensors fixed on it. On encountering of a alert signal from the sensors, the unit transmits the signals to the train using a wireless RF Link also providing a live video about the status to the oncoming train so that the train can the stopped before the accident.
