| Work Detail |
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).
The Surat high-speed rail station concourse is 450 m long while its rail level slab is 450 m long. The first slab at Surat HSR station was cast on 22 August 2022.
Mumbai–Ahmedabad high-speed/bullet train project overview
Mumbai–Ahmedabad High-Speed Rail Corridor is a high-speed rail line under construction in India. It connects the South Asian country’s economic hub, Mumbai, with the city of Ahmedabad in Gujarat.
The 508km project is a part of the 650 km-long high-speed rail corridor that was proposed to run from Pune to Ahmedabad through Mumbai. It comprises 460.3 km of viaducts, 25.87 km of tunnels (including a 7km section undersea), 12.9 km of cut and fill, and 9.22 km of bridges.
The line will have a total of 12 stations in Mumbai, Thane, Virar, Boisar, Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand/Nadiad, Ahmedabad, and Sabarmati. The stations will be constructed either above or next to existing railway stations to provide transfer with the Indian Railways network.
Two rail depots will also be built as part of the Mumbai–Ahmedabad High-Speed Rail Corridor project, one each near Thane and Sabarmati Rail Depot.
Shinkansen E5 trains, which are capable of running at a maximum speed of 350 kilometres per hour (220 miles per hour), will run on the line at a speed of 320 kilometres per hour (200 miles per hour).
Upon completion, Mumbai–Ahmedabad High-Speed Rail Corridor is expected to be the first of its kind in India upon completion, the
Mumbai–Ahmedabad High-Speed Rail Corridor Project team
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. |
