New Delhi: The metro network to be expanded in Delhi and National Capital Region (NCR) under Phase-III will mostly be built underground and there will be more metro stations as compared to Phase I and II.

The major challenge for Delhi Metro Rail Corporation (DMRC) will be three locations where tunnels will be constructed underneath another tunnel. Thus far, there are 31 underground metro stations under the Phase I and II. Under Phase III, 28  underground stations will be constructed on different networks at a stretch of 41.04 km tunnel line.

DMRC spokesperson Anuj Dayal said the decision for building more underground stations under Phase III was made so that common man did not face any problem due to construction work.

“The decision was taken to avoid any damage to flyovers, foot over bridges and under pass falling in the passage of elevated metro line,” he said.

The section from IGI Airport to Kalkaji on the Janakpuri West-Kalindi Kunj corridor will be 17.288km long. The Mukundpur-Yamuna Vihar corridor will have underground lines of 14.386km and the Central Secretariat-Kashmere Gate corridor will have a total of 9.370km underground lines.

DMRC chief E Sreedharan said CISF personnel should also provide services to physically challenged people other than handling security of metro.”
