TRAIN COLLISION AVOIDANCE
The different blocks used to avoid the Collisions:1.Gap Detector2.Vibration Sensor3.Proximity LASER Detector4.LED lighting or Fog penetrating Lights5.FSK Modulator and FSK Demodulator ( Power Line Communication) .A Microcontroller for entireControl. The Microcontroller is interfaced with the input sensing devices such as vibration sensor, Gap Detector andproximity LASER Detector.

TRAIN COLLISION AVOIDANCE
1.Vibration Detector - Train arrival Microcontroller Control Room Power off Stopping of TrainThis vibration detector helps to prevent head on collisions as well as train derailment and during mist conditions.2.Proximity LASER Detector -Standing Train Detector –Micro Controller Jamming the Brakes or Sending info toControl Room Power off Stopping of TrainThis operation helps to prevent the collision of running train over the Standing train3.Gap Detector Gaps in Bends or Curves Info about Trains path –•. Correct Path No problem •. Wrong Path.Microcontroller Jamming the brakes or Sending info to Control Room Gap Correction or Power off Stopping ofTrain

TRAIN COLLISION AVOIDANCE
Result and Discussion
The sensors sense the input and sends to the microcontroller, where it responds and givescommand to the particular component with predefined algorithm. The time parameters are crucialwhich can be easily changed and modified using Micro-controllers. Thus, this device would work incoherence would help to reduce the train collisions.
