The last Tunnel Boring Machine (TBM) of Delhi Metro Rail Corporation's current phase of construction on Thursday bore a 700-metre long tunnel between Najafgarh and Dhansa Stand on the up line, thus signalling the commencing of the Dwarka – Najafgarh – Dhansa Stand corridor. DMRC officials said that the same machine will be subsequently used for tunnelling on the down line between the same stations.

The entire tunnelling work on both the up and down lines will be completed by September later this year.

The total distance between Najafgarh and Dhansa Stand is 1.2 kilometres, all of which is underground. "While 700 metres will be constructed using TBM, the rest will be done by the cut and cover technology in which excavation is done for underground construction and then the area is covered again," a senior official from the rail body said.

This section is an extension of the 4.295 kilometre long Dwarka – Najafgarh Metro corridor. The work for this section was formally awarded in late 2017 and the DMRC is targeting to complete it by December, 2020. Over 90 per cent of construction work is complete on the Dwarka – Najafgarh section, and passenger services are expected to start by September this year.

As part of its third phase of expansion, DMRC has constructed close to 54 kilometres of underground sections, which is more than the underground corridors constructed in its first and second phases. About 30 TBMs were put into use for carrying out such massive underground tunnelling work. It was a tremendous engineering challenge since Delhi is an extremely crowded city and tunnelling had to be done beneath centuries old buildings and congested localities.
