The US$17.15bn project is being implemented by Rail Vikas Nigam and the National High-Speed Rail Corporation (NHSRC).

The Japan International Cooperation Agency (JICA) agreed to fund 81% of the total project cost through a 50-year loan at an interest rate of 0.1% with a moratorium on repayments up to 15 years. The remaining cost will be borne by the state governments of Maharashtra and Gujarat.

Other key players in the project include the Ministry of Railways, the Government of India / HSRC, and a joint venture (JV) comprising Japan International Consultants for Transportation (JIC), NIPPON KOEI, and Oriental Consultants Global.

This is in addition to the General Counsel, Taru Leading Edge, French National Railway (SNCF), and the French Ministry of Finance among others.

Mumbai–Ahmedabad High-Speed Rail Corridor project timeline


In September 2017, India’s Prime Minister Narendra Modi and Japan’s Prime Minister Shinzo Abe broke ground for the start of the construction works that the NHSRCL divided into 27 packages for which it would award contracts separately.


In April, the NHSCRL floated tenders for the construction of the undersea tunnel, and in August of this same year, another tender for works between Vadodara and Ahmedabad was advertised.


In January, the NHSRCL invited final bids for the construction of the Mumbai terminal.

In July of this same year, NHSRCL announced that it had cast the first full-height pier for the Mumbai–Ahmedabad High-Speed Rail Corridor project near Vapi, Gujarat.

In August the agency floated tenders for the construction of the Sabarmati depot.

In September, a Full Span Launching Equipment-Straddle Carrier and Girder Transporter were deployed for use in the project. The equipment, 30 of such will be used in the construction of the project, was indigenously designed and manufactured at Larsen and Toubro’s manufacturing facility in Kanchipuram, Tamil Nadu.

In early October, the first segment for the Mumbai- Ahmedabad HSR corridor was cast at a casting yard near Navsari. These segments are 11.90 to 12.4m in length and 2.1 to 2.5 m in width with a depth of 3.40 m & weighing approx. 60 MT. 19 such segments will make a span of 45m.

In late October, NHSRCL invited bids for the construction of a 21-km long single-tube twin-track tunnel, with a diameter of 13.1 m, between the underground station at Bandra-Kurla Complex and Shilphata in the Thane district of Maharashtra.

15.42 km of tunneling will be carried out with three TBMs and the remaining 4.96 km will be built using NATM.

In early November, the casting of a full-span pre-stressed concrete (PSC) box girder to be used for the project was launched. This was the second PSC box girder developed for the project according to NHSRCL.

All permissions granted for the Mumbai–Ahmedabad rail project

The Mumbai–Ahmedabad high-speed/bullet train project implementation is set to take off. This is after the Maharashtra government through the CM (Eknath Shinde) granted all permissions required for the project.

This move brings to life the project which was stuck due to a lack of the necessary clearances from the government. The permissions included land acquisition, especially at Bandra-Kurla Complex (BKC) and Vikhroli in Mumbai. Reportedly paperwork for acquiring 74% of the total land (433.82 Ha) required in Maharashtra for the project has been completed so far.

However, the National High-Speed Rail Corporation Limited (NHSRCL) had had physical possession of only 39% (168 Ha) of land. The remaining had been pending since 2019 when the MVA government was formed.

Directive to sort out the land acquisition issues

Maharashtra Chief Secretary Manukumar Shrivastava undertook a review of the bullet train project. He told the collector of Mumbai Suburbs, Nidhi Chaudhari, the collector of Thane, Rajesh Narvekar, and the collector of Palghar, Manik Gursal, to sort out the land acquisition issues.

Furthermore, Shrivastava asked the Mumbai Metropolitan Region Development Authority (MMRDA) to hand over the Bandra plot to the NHSRCL and shift the petrol pump and fire station at Bandra-Kurla Complex (BKC) and Vikhroli in Mumbai soon.

Other clearances hindering the start of the project

Apart from the land acquisition, forest clearance in the state was also pending.

Speaking on the project an official close to it said, “Shifting of Maharashtra State Electricity Transmission Corporation Limited (MSETCL) lines and Forest Clearance Stage-I for 29.32 ha forest land for shifting of EHV lines pertaining to PGCIL and MSETCL in Palghar and Thane districts and shifting of DC Earthing Station, for rolling stock depot, to an alternate location by MSETCL in Thane district was also pending.”

Construction of a track system begun in Surat

The construction of a track system for the Mumbai-Ahmedabad High-Speed Rail corridor track system has begun in Surat, India.

This track system is a one of kind in the country. It is not a traditional or ballasted track system that comprises rail fixed to sleepers supported by crushed stones. Instead, it is a ballastless track system like the one used in Japan’s high-speed rail system, the Shinkansen.

The system comprises a pre-cast track slab over which fastening devices and rails are fitted. The slab rests on a reinforced concrete (RC) track bed which has a thickness of approximately 300mm and a width of 2,420 mm.

RC anchors which are 520 mm in diameter and 260 mm tall are fixed to help avoid any longitudinal and lateral restraint to the track slab. These anchors are constructed at approximately 5 m from centre to centre.

Concourse and rail level slab construction complete at Surat high-speed rail station

Late last month, Surat high-speed rail station became the first station on the Mumbai-Ahmedabad high-speed rail corridor to complete the construction of the concourse and rail level slab. This was revealed by the Nation High-Speed Rail Corporation Limited (NHSRCL).
