Rocks posed a hurdle during the drilling operation. However, the machine continued to drill through safely. On average, 3.5 km were covered per day. On some days, even half a kilometer was difficult to drill due to rocks.

The underground route is a part of the new line from Kalenga Agrahara to Nagawara proposed in Phase 2 of the metro project. It consists of 7.5 km of an elevated corridor and 13.76 km of an underground corridor. The corridor has 18 stations and almost 22 km of tunnels. The name of the stations are Kalenga Agrahara, Hulimavu, IIMB, JP Nagar 4th Phase, Jayadeva Hospital, Tavarekere, Dairy Circle, Lakkasandra, Langford Town, National Military School, Mahatma Gandhi Road, Shivaji Nagar, Cantonment, Pottery Town, Tannery Road, Venkateshpura, Kadugundanahalli and Nagawara.
The route of the underground corridor has been divided into four sections. TBM Urja will also be tunnelling a route from the Cantonment station to the New Pottery Town station. This line, which will run through the heart of the city, will ensure complete metro connectivity to the Kempegowda International Airport in Bengaluru after its completion.
