The railway network of India is the biggest in Asia and perhaps the most complicated in all over the World. There are so many different types of trains like local, fast, super-fast, passengers, goods etc. and their so many multiple roots. Although the time table is perfect it is not at all possible to maintain it. And that’s why the train accidents are becoming more and more usual. So in this paper a little kind of intelligence is added to the train engines so that it tries to avoid train accidents. The idea is whenever any engine observes a red signal on its track, it will start decreasing its speed gradually and stops automatically at some distance from the signal pole. After that when it gets green signal the train will automatically gain speed and go on. In the mean time when the train has not stopped yet and a red signal becomes green then it crosses the signal pole with low speed and then the speed will increase gradually.
