Chennai Metro to deploy made in India tunnel boring machines for Phase II project

Chennai Metro Rail Ltd. is all set to deploy made in India tunnel boring machines for its Phase II project. According to CMRL officials, of the 23 TBMs to be used in the project, 12 would be from Tamil Nadu, five from China, one from Germany and one from Pune respectively. The status of four TBMs is not known yet because the contract for the stretch between Kolathur and Nathamuni in the Corridor 5 of Phase 2 project has not been awarded yet. “These 19 TBMs will be commissioned for the Phase II project one after the other between October and June next year,” the official said.
