An anti-collision systems for railways: Part-1

The project idea is to create a system to prevent the trains from colliding with each other i.e to prevent the accident of trains. Now for simple  idea of projects :
Each train has some IR(very intense and highly collimated beam) transmitter as well as receiver at the front and at the back of trains .Now total  the system consists of IR Transceiver and Microcontroller. Now each train has some unique ID (Train Number) that is there inside the microcontroller ROM. Now When two trains will come nearly face to face  i mean consider the situation when two trains coming head on –on  a single line, now when ever they are at a distance between the range of IR transmitters then both train will  receive a transmitted signal form each other  microcontroller will give proper signal so that the  actuator/relay may be able to stop the trains before they collide.
But for this situation to occur following important things need to be considered and tested accordingly.
What are the ranges of the train’s IR transceivers ? Is that range is sufficient to stop the trains at that distance before they collide. As each train will take some distance or move a considerable amount of distance after is breaks are pressed or activated and trying to stop .Also at what velocity the trains are approaching to each other: So those  information are required to know, what IR range and transceivers we are going to choose .for example if the trains for which this system is going to be implemented the maximum possible speed say 200 Km/Hr, and say when the  trains are running at their maximum speed, then it need to be tested that within  how much distance the trains will be stopped after it the breaks are pressed.
Now another things are needed to be considered -are the tracks are linear because the IR sensor etc will work only for linear tracks( i.e. straight line).
So these things are to be taken care off when doing or creating the design according to this methodology.

NOW part 2 will have another approach for anti-collision system design.
