In early days the mode of transportation is very slow as the time passes world made progress and the different revolution takes place which demands the fast mode of transportation. The new generation of fast transportation are the railways, airplanes, cars etc. The railway transportation is very important for any nation. Railways is very fast service and hence there is a possibility of accidents like collisions, derailment and accident due to weather condition.
The project is based on how to avoid these collisions by makeing a device which sense if there is an obstacle in path of the train or any another is coming on the same track from another side. The project deal with the condition of collision between two trains and try to find out the method to avoid the collision in normal and abnormal condition.
