Passenger services on the 4.29-km Dwarka-Najafgarh section of the Delhi Metro are expected to begin by September, officials said. Over 90% of construction work on the stretch has been completed. The work on the Najafgarh-Dhansa Stand section using a Tunnel Boring Machine (TBM) also started on Thursday.

More Information:

  • The TBM will bore a 700 m-long tunnel in the 1.2 km-segment.
  • The Najafgarh-Dhansa Stand section is an extension of the Dwarka-Najafgarh segment.
  • The DMRC said in a statement,”The work for the Dwarka-Najafgarh section was formally awarded in late 2017 and the target date for completion is December 2020. On this section, over 90% of the construction work has been completed and passenger services are expected to start by September.”
  • The TBM first used on the up line will be subsequently used for tunnelling on the down line between the same stations, a DMRC spokesperson said.
  • He said that the entire tunnelling work on both the up and down lines will be completed by September this year.
  • The Najafgarh-Dhansa Stand stretch is entirely underground.
  • The DMRC said, while 700 m of it will be constructed using the TBM, the rest will be done using ‘cut and cover’ technology in which excavation is done for underground construction and then the area is covered again.
  • As part of its phase-3 of expansion, the DMRC said it has constructed close to 54 km of underground sections, which is more than the span of such sections constructed in its first and second phases.
  • The statement said,”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.”
  • TBMs were introduced for the first time by the DMRC during the phase-1 of metro construction work.
  • 14 TBMs were used in Phase-2, while in Phase-3, the number of such machines used was 30, it added.
  • Currently, the Delhi Metro operates a network of 327 km with 236 metro stations.
  • It said, this network includes over a 100 km of underground lines spread across the national capital.
