Representatives from Afcons Infrastructure Ltd., Sam India Consortium, Uttar Pradesh Metro Rail Corporation (UPMRC) and TERRATEC have celebrated a significant milestone on India’s Agra Metro project. The 6.61m diameter EPBM S115 has completed its final breakthrough on a 2.2km up-line tunnel section.
Originally employed as a 7.51m diameter EPBM for India’s first Regional Rapid Transit System Project spanning 82km to connect Delhi, Ghaziabad, and Meerut, TBM S115 has been refurbished and converted into a 6.61m diameter EPBM. It now plays a crucial role in constructing this 2.2 km up-line tunnel from RBS College Ramp to Agra College Interchange Station. TBM S115 has been successfully re-engineered for the Agra project, where it tackles challenging clayey silt, sandy silt, and silty sand conditions, completing the 1942m drive in under a year.
The project utilises TERRATEC’s 275mm thick x 1400mm long reinforced concrete Universal-style pre-cast lining rings, efficient muck removal via rolling stock, and three 45t battery locomotives, further demonstrating TERRATEC’s commitment to integrated project delivery.
The Agra Metro Phase 1 project encompasses a 14.25km Line-1 route from Sikandra to Taj East Gate. This milestone marks S115’s third successful completion and contributes to the seventh breakthrough on the Agra Metro Line-1’s underground section, outside the operational Priority Corridor, between RBS Ramp and Mankameshwar Mandir Station. TBM S115 will be later redeployed for Jaipur Metro project.
