First TBM Arrives in Pune, Swargate-Katraj Underground Metro Tunnelling Set to Begin in January

05 Nov 2026

 

The first of four tunnel boring machines for the Swargate-Katraj Metro extension has arrived in Pune, and tunnelling is expected to begin in January. The machine will be assembled and lowered underground to start excavation as soon as the launching shaft at Swargate is ready. Work on the shafts is already underway, and excavation of the shaft at Market Yard station has begun. These shafts will be used to lower machinery and equipment for tunnelling and other underground construction work.

The 5.46 km stretch will be entirely underground. Tunnelling will be done from both ends at the same time, with two TBMs working from Swargate and two from Katraj, and all four machines meeting at Padmavati. Because of the rocky ground along the route, MahaMetro has set a target of about 10 metres of tunnel per day for each machine, based on its experience from the first phase of the Metro project. The TBMs will work at a depth of around 28 metres below ground level. Once complete, the extension will take Metro service directly to Katraj, benefiting commuters from Katraj, Market Yard and Padmavati, and easing traffic congestion in south Pune. For a part of the city that has waited a long time for this line, January is the date to watch.
