More Details:

Patna Metro Rail Project achieved a significant milestone on Wednesday, 20th March 2024 as the 450-t EPB TBM -01 achieved its first tunnel breakthrough. The Tunnel Boring Machine (TBM), reached the Patna University metro station, marking the first tunnel breakthrough for the city-shaping Patna Metro. The breakthrough was initiated by Advisor (Special Works) Shri Daljeet Singh.

The TBMs work till date in this Project:

  • The TBM was commissioned in the month of May 2023 at Moin Ul Haq stadium, which constructed a 1.5 km long tunnel between MUH and Patna university.
  • TBM-1 has worked around the clock to build a 1.5 km of fully lined tunnel, which completes the first drive of its 1.5 km journey towards the Gandhi Maidan.

  • Being a densely populated and old building structure, this stretch was one of the most challenging stretches of the Patna metro tunnelling.


As the Patna Metro Rail Project continues to forge ahead, the successful tunnel breakthrough by TBM-01 at Patna University metro station stands as a beacon of progress and innovation. It heralds a new era of urban mobility in Patna, promising a future where the city’s transport infrastructure is aligned with the needs and aspirations of its people.
