Gulermak – Sam India Builtwell on Monday commissioned tunnel boring machine S92 at Bada Chauraha Station for constructing the first 3.619 km underground section of the 32.4 km Kanpur Metro Phase 1 project.

Nicknamed Tatya after Tatya Tope, this refurbished 6.52m diameter & 120m long Terratec Earth Pressure Balance (EPB) machine had previously bored and built a portion of Lucknow Metro’s Line-1. Gulermak – SAM began lowering its parts into the station’s launch shaft in early July.

Per the tunneling plan, this machine on the down-line along with new TBM S93, nicknamed Nana, on the upline will be deployed on Package KNPCC-05 for a total of 4 drives each:

• Bada Chauraha to Nayaganj: 989.5m
