Automatic Block signaling system is one of the efficient train handling system.
It is used in many countries including India.
In India we can see this system in Mumbai,Kolkata,Chennai,Vizag etc.
In this, Train acts as self blocking system.It occupies block and release Previous block.
Keeping one block Isolation,Following block again gets ready to accept new train with Yellow signal.If Next train is not running immediately then signal follows sequence like Yellow,Double Yellow and green.
When next train enters,Respective signal becomes RED and Process repeats.
In case of Failure all signals goes to Default state i.e RED ( Danger).
