DMRC sets new deadline for Delhi Metro Phase 4 Corridors

New Delhi, India (Metro Rail Today): The Delhi Metro Rail Corporation Limited (DMRC) has extended deadline for commissioning of under construction corridors of Delhi Metro Phase 4. 

According to new deadline, the Janakpuri West - R K Ashram Marg corridor, which is an extension of the Magenta Line, is expected to be operational only by March 2026, a delay from its earlier September 2025 deadline. The Tughlakabad-Aerocity corridor (Silver Line) is likely to be completed by March 2025, as against the previous deadline of September 2025; the Majlis Park-Maujpur corridor (Extension of Pink Line) of Phase IV expected to be completed by March 2025, as against an initial deadline of November 2024.

DMRC said that work on 4 km elevated viaduct, which was recently completed, is now being offered to system contractors for track laying and traction work such as erection of over-head electrification (OHE) masts.

“The structural work for the viaduct will soon be completed till Haiderpur Badli, as just a crossing over a railway track is left there. This is an important achievement for DMRC’s engineers since the work on this corridor had started amidst the Coronavirus crisis and had to face intermittent delays due to the pandemic, and issues pertaining to tree-cutting clearances,” said Anuj Dayal, principal executive director, corporate communications, DMRC. The work on this section was completed without causing any major disruption to the flow of traffic below, he added.

So far, around 2.2km of underground tunnel work has been completed between Janakpuri West and Krishna Park Extension. On Friday, another tunnel boring machine (TBM) was lowered for tunnelling work between Derawal Nagar to Pulbangash.

“This TBM drive will achieve depth up to 25.9m near the Najafgarh drain. The movement of the TBMs are being monitored round the clock digitally by DMRC since there are a lot of old buildings above,” he further said.

Under its Phase 4, DMRC is constructing a total of three corrdiors with total network of 65.2 kilometres and 46 stations. Out of two are extension of existing lines and one is new line known as Silver Line. This expansion includes the Janakpuri West-RK Ashram Marg, Majlis Park-Maujpur, and Tughalakabad-Aerocity corridors. A total of 11 new interchange stations will also come up as part of this new expansion.
