Delhi Metro Phase 4 TBM 367 and 372 pass factory acceptance test

Robbins, the tunnel boring machine manufacturer for the 65.1 km Delhi Metro Phase 4 project, has completed factory acceptance testing (FAT) on TBM 367 and TBM 372.

The restored 6.5 m diameter Earth Pressure Balance (EPB) devices will be used by Afcons Infrastructure. They were initially used to construct the Singapore MRT before being transferred to Robbins' yard in Gurgaon's Sector 74.

Afcons will deploy TBM 367 and three additional Robbins machines to operate on Package DC-05 of the Delhi Metro Magenta Line's 28.92 km Janakpuri West-RK Ashram extension.

The 7.46 km subterranean stretch connects a ramp north of Derawal Nagar to RK Ashram via six stations: Derawal Nagar, Ghanta Ghar, Pulbangash (interchange with Red Line), Sadar Bazar, Nabi Karim, and Ramakrishna Ashram Marg.

Afcons was awarded a Rs 24.81 billion contract by the Delhi Metro Rail Corporation (DMRC) for Package DC-05 in January 2022, with a 42-month timetable.

Afcons will send TBM 372, another Robbins machine, and two Herrenknecht machines to work on Package DC-07 of the Delhi Metro's 23.622 km Silver Line, which connects 16 stations from Aerocity to Tughalakabad.

Package DC-07 will connect the eastern terminus of Sangam Vihar Station to Sarita Vihar Depot via three stations at Maa Anandmayee Marg, Tughlakabad Railway Colony, and Tughlakabad, where it would connect to the Violet Line station built in Phase 2.

Package DC-07 was granted a Rs 16.69 billion contract in January 2022, with a 42-month completion period.
