Indore Metro to Start Underground Tunnelling With a 1,000-Tonne Tunnel Boring Machine From the Airport
Indore Metro is about to start work on its first underground section using a tunnel boring machine of around 1,000 tonnes, brought in from Thailand. Digging starts near the airport and runs towards Kalani Nagar. The machine has a 6.5 metre cutting head and can dig close to 20 metres of tunnel a day, putting the reinforced concrete lining in place as it goes. Two parallel tunnels will be built, one for trains heading into the city and one for the return. The underground network comes to about 12 km in total, and the full section is expected to take four to five years.
