Signalling

The signaling requirements for Delhi Metro have been worked out keeping in mind the smaller headway of train operation and consequent safety requirement for effective, smooth and safe operation. The strain on driver is reduced by deploying the built in safety feature of speed regulation, braking and fast flow of information.

Delhi Metro shall use ATP/ATS system of CATC for rail corridor whereas on the Metro corridor full CATC (i.e. ATP + ATS + ATO) shall be used.
