The over 4.2 km-long Grey Line of the Delhi Metro, which will connect urban village area of Najafgarh to the rapid transit network, was inaugurated on Friday, 4 October.
Union Housing and Urban Affairs minister Hardeep Singh Puri and Chief Minister Arvind Kejriwal flagged off a train on the corridor.
Passenger services will commence from the evening.
Puri said with the opening of this corridor, the Delhi Metro has covered 377 kilometres in Delhi-NCR.
Kejriwal said people of Najafgarh had been demanding this for a long time. People residing in the rural areas will be benefitted by the corridor, he said.
The corridor consists of three stations-- Dwarka (interchange with Blue Line), Nangli and Najafgarh.
Dwarka Metro Station As Interchange Facility
"The Grey Line is a standard-gauge section and out of the 4.295 km, 2.57 km is elevated and 1.5 km underground. With the opening of this section, the Dwarka metro station is all set to emerge as an interchange facility that will connect the sub-city with the locality of Najafgarh," Dayal had earlier said.
Commissioner of Metro Rail Safety (CMRS) Janak Kumar Garg had accorded the mandatory approval for starting passenger operations after inspecting the corridor for safety on Wednesday.
Dayal said a peak hour frequency of 7 minutes and 30 seconds shall be maintained on this stretch.
The total travel time on this section shall be 6 minutes and 20 seconds and three trains shall ply on this section and a fourth train has been planned, he said, adding that at present, the DMRC runs 376 trains, spanning 2,206 coaches and 4,778 trips per day.
Trial runs on the section had begun in July.
The Delhi Metro Rail Corporation had earlier said the corridor is being extended by another 1.18 km till Dhansa Stand, which is slated for completion by December 2020.
An 80 metre passageway connects the old Dwarka station of the Dwarka Sector 21 - Noida Electronic City/ Vaishali corridor or the Blue Line with the new station on the Grey Line, which has come up as part of the extension to Najafgarh.
There will be concourse to concourse connectivity through the paid area.
