Why in the News?

The Union Railways Minister Ashwini Vaishnaw announced the successful breakthrough of the second mountain tunnel of the Mumbai–Ahmedabad High-Speed Rail (MAHSR) project in Palghar, Maharashtra, marking a major milestone in India’s first bullet train corridor. This achievement comes after obtaining the necessary environmental clearances and conducting a thorough environmental impact assessment for the project.

Major Milestone in MAHSR Project

  • The tunnel is 454 metres long and 14.4 metres wide, designed to accommodate both up and down tracks of the bullet train.
  • This breakthrough was achieved within one month of the first tunnel breakthrough on 2 January, reflecting rapid construction progress while adhering to environmental jurisprudence.
  • The development is part of the Mumbai–Ahmedabad High-Speed Rail Project, India’s first high-speed rail corridor, which has undergone rigorous environmental clearance processes.
  • The Minister praised engineers and workers, noting that the project showcases India’s growing technical and execution capabilities while following the precautionary principle in environmental matters.

Technology, Timelines and Regional Impact
