New Delhi/Mumbai: India’s first high-speed rail corridor — the Mumbai–Ahmedabad High-Speed Rail (MAHSR) project — has recorded strong construction progress as of December 9, 2025, with major civil engineering, tunneling, and system installation activities advancing rapidly across Maharashtra and Gujarat.
The National High Speed Rail Corporation Limited (NHSRCL) has reported significant traction across multiple work fronts, signalling that India’s debut bullet train corridor is entering a decisive stage of implementation.
First Bullet Train Corridor: Massive Progress in Viaduct and Pier Construction
Civil works continue to form the backbone of the project, with rapid progress visible across the 508-km alignment:
- 330 km of viaduct completed, forming a large share of the elevated track structure
- 408 km of piers finished, enabling faster segmental construction of spans
- The viaduct structure is crucial to maintaining the highly precise geometry required for Shinkansen-style operations at 320 kmph.
Bridge Works Hit Major Milestones
NHSRCL’s update highlights considerable advancement in large-span bridges:
- 17 river bridges completed
- 11 steel bridges installed
- 5 pre-stressed concrete bridges finished
- The first 130-metre span of a planned 230-metre steel bridge has been erected, marking one of the corridor’s most demanding long-span engineering feats.
These bridges, spread across varied terrain, are essential to seamless high-speed operations.
Noise Barriers Installed Across 235 km Stretch
To meet global Shinkansen noise standards, the project has intensified noise mitigation efforts. As of now:
- Over 4.7 lakh noise barriers have been installed
- Covering 235 km across the route
These structures are designed to reduce noise impact in urban, suburban and sensitive zones along the corridor.
Track Bed and Electrification Work Picks Up Speed
The track infrastructure is witnessing steady progress:
- 260 track km (130 route km) of Reinforced Concrete (RC) track bed completed
- 3,700 OHE masts installed
- Electrification works cover approximately 85 route km
This forms the foundation for the slab track system, a signature feature of high-speed rail that ensures vibration-free, maintenance-efficient tracks.
First Bullet Train Corridor: Tunneling Advances in Palghar and Undersea Corridor
The tunneling component — among the most complex parts of MAHSR — continues to move forward:
- Mountain Tunnels (Palghar District)
- Excavation underway for seven tunnels
- Geological and technical challenges managed with advanced tunneling methods
- BKC–Shilphata Underground Tunnel
- 21 km total length, including India’s first undersea tunnel
- 5 km excavated using the New Austrian Tunnelling Method (NATM)
This section includes high-end engineering and the deepest underground station of the project at BKC.
First Bullet Train Corridor: Rolling Stock Depots in Surat & Ahmedabad Taking Shape
Key operational facilities required for the Shinkansen E5-type bullet trains are progressing:
- Depots at Surat and Ahmedabad witnessing construction activity
- These facilities will handle maintenance, stabling, inspection and readiness of high-speed train sets
- Stations Progressing at Fast Pace Across Both States
Gujarat
All high-speed stations are in advanced superstructure stages
- Likely to be ready ahead of the Maharashtra stretch
Maharashtra
- Construction initiated for all three elevated stations
- BKC underground station progressing with base slab casting underway
- BKC will serve as the originating terminal and is the most complex station in the network
First Bullet Train Corridor Project Momentum Strong After Early Hurdles
The project faced early delays due to land acquisition and environmental clearances, particularly in Maharashtra. However, since 2023:
- All major clearances have been secured
- Land acquisition in Maharashtra is nearly complete
- Works have accelerated significantly on both ends
With civil works, system installations, tunneling and station building progressing simultaneously, the MAHSR project is on track to position India among nations with full-fledged high-speed rail operations.
First Bullet Train Corridor: A Transformational Project for Western India
Once operational, the Mumbai–Ahmedabad Bullet Train will:
- Cut travel time to around two hours
- Boost industrial, economic and tourism growth between Maharashtra and Gujarat
- Enhance regional connectivity
- Usher India into the era of true high-speed rail
