Delhi Metro Rail Corporation Limited (DMRC), a state-owned company with equal equity participation from the Government of India and the Government of Delhi, built and operates the Delhi Metro.

The Delhi Metro is a metro system serving Delhi and its satellite cities of Noida, Gurgaon, Ghaziabad, Faridabad and Bahadurgarh in the National Capital Region of India.

Signalling and Telecommunication

The Delhi Metro uses cab signalling along with a centralised automatic train control system consisting of automatic operation, protection and signalling modules.

A 380 MHz digital trunked TETRA radio communication system from Motorola is used on all lines to carry both voice and data information

For Blue Line Siemens Transportation Systems has supplied the electronic interlocking Sicas, the operation control system Vicos OC 500 and the automation control system LZB 700 M

An integrated system comprising optical fibre cable, on-train radio, CCTV, and a centralised clock and public address system is used for telecommunication during train operations as well as emergencies.

For Red and Yellow lines ALSTOM has supplied signalling system and for Green and Violet lines, Bombardier Transportation has supplied CITYFLO 350 signalling system.

The Airport Express line has introduced WiFi services at all stations along the route on 13 January 2012.

Connectivity inside metro trains travelling on the route is expected in the future. The WiFi service is provided by YOU Broadband and Cable India Limited.

A fully automated, operator less train system has been offered to Delhi Metro by the French defence and civilian technologies major Thales.
