The Mumbai–Ahmedabad High-Speed Rail (MAHSR) project has reached a key construction milestone, with 185 kilometres of reinforced concrete (RC) track bed completed, marking steady progress in India’s first bullet train corridor.
According to project authorities, the work is advancing rapidly across multiple construction bases in Gujarat, where large-scale infrastructure development is underway for the 508-km high-speed rail line connecting Mumbai and Ahmedabad.
J-Slab System Introduced for High-Speed Rail
A major feature of the project is the deployment of the Japanese J-Slab ballastless track system, used for the first time in India. This advanced technology, derived from Japan’s Shinkansen network, is designed to support ultra-high-speed train operations.
The system includes a reinforced concrete track bed, pre-cast slabs, and a precision alignment layer using Cement Asphalt Mortar (CAM), ensuring long-term stability and smooth operations at speeds up to 320 km/h.
Manufacturing and Installation Progress
Officials reported that:
- Approximately 188 km of track slabs have been manufactured
- CAM layer installation and slab laying have progressed over 70 km
- Multiple Track Construction Bases (TCBs) are actively supporting rapid execution of works
Mechanised systems, including slab laying machines and advanced welding technology, are being used to improve accuracy and speed in construction.
Key Infrastructure Project for India
The Mumbai–Ahmedabad bullet train corridor is one of India’s most ambitious infrastructure projects, aiming to transform intercity travel by significantly reducing journey time between the two major economic hubs.
Once completed, the project is expected to bring world-class high-speed rail connectivity to India, boosting regional development and modernising the country’s transport infrastructure.
