Mumbai Metro gets its first Tunnel Boring Machine
The Mumbai Metro Rail Corporation Limited has received its first Tunnel Boring Machine (TBM), which will be used to drill twin tunnels for the 33.5-km Colaba-Bandra-SEEPZ Metro-3 line. MMRC will receive 16 more TBMs over the next two years. The TBM operator will reportedly sit in an air-conditioned cubicle within the machine, which also has its own sanitation system.
