As shared earlier:

  1. The scope of the package includes tunnels up to the existing Sarita Vihar depot, which will be extended to stabilize and maintain Silver Line train-sets,
  2. DMRC will require AFCONs to use at least 5 Tunnel Boring Machines (TBMs).
  3. The distance from Sangam Vihar station to Maa Anandmayi Marg is 3.014 kms for a walk around Tughlakabad Fort and other important monuments/mausoleums scattered in the area. The Twin Tunnel here will be the longest tunnel between adjacent stations on the entire network.
