  4. Signal Sensar circuit & Breaking Circuit

As per the second cause, in a single track the drivers of both the trains are not in a position to see one another. So the accident takes place.

By using this system, the driver could know the arrival of another train from some kilometers. The train would come to a halt automatically in between one kilometer, even in the absence of the drivers contact.

In every train, there is an automatic F.M. receiver and an F.M. transmitter.

F.M. receiver automatically and clearly observes the F.M. transmitter from the other train and alerts the driver through siren or indicator. The same thing would happen to the other train and alerts the driver through siren or indicator. The same thing would happen to the other train and alert the driver. By this method both the drivers are in a position to know the track, place speed and distance on running, and thereby avoid accidents.

Even if the driver would not notice the indicator, due to the increase in DP range, brake applies automatically with the help of Micro process.

A micro chip is fitted in each train in order to eject the same signal.

This is used to eject the already spoken signal and unnecessary signal at a particular time.

This ensures the functions of the four circuits. This automatic system is advisable to the put off at the cities and the stations.
