Radars are secure in the railway trajectory 1. Ultrasonic Sensor 2. IR Sensor. Ultrasonic sensor is used to detect cracks or snags in the track. IR sensor calculate the distance between train and the place where the crack is occur. The sensed datum send to the vile class using data transmit. The sordid rank information is also sending to the waitron and data base. The admin will access the material which is server. The base station evidence is send to the auto play back record. This is present in the train next to the driver and also sends to LCD display. Then the train will get slow. And also generate power by dynamic energy.
