The first tunnel boring machine (TBM) for Indore Metro's underground section, named 'Narmada', has been successfully launched into the airport shaft, marking a significant step forward in the city's metro construction.
The Madhya Pradesh Metro Rail Corporation has successfully deployed its first tunnel boring machine, 'Narmada', into the airport shaft at Indore, a milestone that is expected to accelerate the underground construction of the city’s metro line.
Weighing 410 tonnes, the TBM was launched from a dedicated shaft near the airport, where it will begin excavating the tunnel that will carry the metro through the heart of Indore. The machine’s arrival marks the first use of this technology in the state’s metro projects.
Officials say the launch is a key step toward meeting the project’s timeline, with the TBM expected to start boring within weeks. The deployment also demonstrates the growing use of advanced tunneling equipment in India’s rapidly expanding urban rail networks.
