The final breakthrough on a 2.2km upline of India’s Agra Metro project, has been celebrated by Terratec, Afcons Infrastructure, Sam India Consortium and Uttar Pradesh Metro Rail Corporation.
A Terratec 6.61m-diameter EPBM broke through on the tunnel from RBS College Ramp to Agra College Interchange Station in November 2024.
As a 7.51m-diameter EPBM, TBM S115 originally was employed for India’s first regional rapid transit system project spanning 82km to link Delhi, Ghaziabad, and Meerut, and currently has been refurbished and converted into a 6.61m-diameter machine. In order to advancing the Agra project It has been re-engineered and has tackled challenging clayey silt, sandy silt, and silty sand conditions. It completed the 1.942km drive in less than a year.
Also the Terratec’s 275mm-thick x 1400mm-long reinforced concrete Universal-style pre-cast lining rings, efficient muck removal via rolling stock, as well as three 45-tonne battery locomotives, are being used in this project.
Stretching from Sikandra to Taj East Gate, the Agra Metro Phase 1 project is a 14.25km Line-1 route and this latest breakthrough marks S115’s third completion and is the seventh breakthrough on Line-1’s underground section, outside the operational Priority Corridor, between RBS Ramp and Mankameshwar Mandir Station.
TBM S115 will later be redeployed for the Jaipur Metro project.
