Train derailment in curves and bends Sensor sense continuously. µc doesn’t get value. µc sends signal to µc in train side Using zigbee transceiver section Power supply will cutoff Train will be stopped.

Automatic railway gate control Sensor sense vibration 3 km away. Output given to µc µc give instruction to close the gate Gate is closed automatically using servomotor. Gate is opened after the train is passing

OVER ALL WORKING The proposed model makes use of ZigBee protocol as a medium of transferring information

Result and Discussion The sensors sense the input and sends to the microcontroller, where it responds and gives command to the particular component with predefined algorithm. The time parameters are crucial which can be easily changed and modified using Micro-controllers. Thus, this device would work in coherence would help to reduce the train collisions. Train safety

CONCLUSION In this project, an anti-collision system for trains have been designed, simulated and tested. The simulation has been done using proteus electronic simulation package Train collisions , de railing & rail road accidents are avoided. Hence it is expected that, major train mishaps can be prevented and human life saved if this system is implemented.
