DMRC constructs underground tunnel without disrupting services on Red Line
New Delhi: Delhi Metro Rail Corporation (DMRC) constructed an underground tunnel at Pulbangash below the already operational Red Line of the Delhi Metro network. This tunnel was constructed as part of the upcoming Janakpuri West–RK Ashram Marg corridor, an extension of the Magenta Line. The tunnel was built between the Pulbangash and Sadar Bazar stations, even as trains on the busy Red Line above were not halted for a single day.
“This tunnelling work was challenging as the Tunnel Boring Machine (TBM) carefully constructed the tunnel below the elevated viaduct on which trains were operational.
