Delhi Metro Update: Track laying work on Mayur Vihar-Trilokpuri Sanjay Lake stretch of Pink Line to be completed by June-end

Following the completion of civil work, now, the track laying and other ancillary works have been commenced on the Delhi Metro’s Pink Line between Mayur Vihar Pocket – 1 and Trilokpuri Sanjay Lake. In addition, Overhead Electrification work is also under progress.

• The track laying work is expected to be completed by the end of June.
• Preliminary trials are expected to start thereafter.
• All efforts are being made to further expedite the progress of work on this particular stretch.
• The section shall be operational immediately after receiving the mandatory clearances from all concerned authorities.

Unique construction method:

• To expedite work on the Trilokpuri section of Pink Line, the Delhi Metro adopted a unique construction method by using steel girders instead of the conventional concrete ones.
• Construction of concrete girders would have required the establishment of a casting yard and it would not have been feasible to set up a casting yard for such a small stretch within a short duration of time.
• Therefore, steel girders were installed on this stretch.
• A total of 40 steel girders have been placed on 10 spans for the 290 metre-long section.
• These steel girders have been fabricated and brought from a workshop at Ambala in Haryana.
• This has not only saved time but also there was no need to create a separate casting yard for the concrete casting of the girders.
• The length of these girders varies from 16 to 38 metres.
• The height of the viaduct stands at about 8 to 9.5 metres.
• A curved span of radius 200 metres is also a part of this stretch.
• Earlier, for the construction of the Chattarpur Metro station also, DMRC had adopted a similar method of using steel structures because the construction of that station was also delayed due to land acquisition issues.
• The work on installing these steel girders and casting of deck slab was completed in April just before the second surge of the Covid pandemic.
• This was a significant achievement because the civil construction on this stretch was started in early 2020 and was repeatedly hampered by the pandemic induced lockdowns and issues such as non-availability of workforce.

Connectivity:

• Once completed, this section will connect the two ends of Pink Line and will provide seamless connectivity to a long range of localities in the National Capital Region.
• Important transport hubs such as Nizamuddin Railway Station, Sarai Kale Khan ISBT, Anand Vihar Railway Station, Anand Vihar ISBT, Delhi Cantt. Railway Station, and prominent markets like Dilli Haat – INA, Sarojini Nagar and Lajpat Nagar will get direct connectivity through this corridor.

Longest single Metro corridor:

• This corridor will further be extended from Majlis Park to Maujpur in Phase – IV, making it the longest single Metro corridor in India at approximately 70 kilometers.
• After completion of the Phase – IV, the Pink Line will also become the only Ring Corridor of Metro in the country.

Additional Details:

• DMRC is also developing an internal road below the viaduct at Trilokpuri which will connect the Vasundhara Road and Trilokpuri Road.
• The road will be 140 metres in length.
• This will help in decongesting the area and will ease the traffic scenario.
• While the presently operational sections of the Pink Line were made functional in 2019, this small stretch got delayed due to the unavailability of encumbrance free land.
• After following the due process of law, the land was acquired and R&R (Rehabilitation and Resettlement) of Project Affected Persons was done for commencement and completion of construction work.
