Extensions to Delhi’s metro network opened for operational service
New train for Delhi's Metro Lines 7 and 8
Operational service has started on the extended Lines 7 and 8 on the Metro system in India’s capital, Delhi.
The new trains for the Metro extensions were constructed by Alstom, as well as the design and installation of the signalling system. Line 7 is called the Pink line, and the extension provides connections with three other Delhi Metro lines: the Yellow, Red, and Pink Lines, and runs from Majlis Park to Maujpur.
It will eventually be a circular route around Delhi, and will be India’s longest metro line capable of unattended train operation.
Alstom’s Urbalis Flo signalling system, a Communications-Based Train Control (CBTC) system designed to operate trains with Grade of Automation (GOA) 4, driverless features, will control the trains for the Line 7 extension.
Line 8, the Magenta line, has been extended from Majlis Park to Deepali Chowk, with plans in place for a future extension to RK Ashram and Janakpuri.
Alstom also has a €312 million contract to supply 312 cars for Phase IV of the Delhi Metro.
These are all being built by Alstom at its state-of-the-art facility in Sricity, Andhra Pradesh, and are designed for driverless operation, with a maximum speed of 95 kph and a normal operating speed of 85 kph.
They will supplement more than 800 metro cars that Alstom has already supplied to the Delhi Metro network in partnership with the Delhi Metro Rail Corporation (DMRC)
Alstom has also recently secured a 10-year maintenance contract for Delhi Metro Lines 1 and 2 at DMRC’s Badli depot.
This includes comprehensive annual maintenance of the trains, machinery, plant systems, and housekeeping.
Elsewhere in Delhi, the company provided train control and signalling systems for the Red, Yellow, Green, Violet and Pink Lines during Phases I, II and II of the Metro rollout.
“We are honoured and proud to be a long-standing partner of DMRC through its journey of becoming one of the world’s largest metro networks today. Together, we are committed to providing a safe, efficient, and environmentally friendly travel experience to commuters and the Magenta and Pink line extension will truly enhance DMRC’s neural metro network connectivity in the region”.
