The Mumbai-Ahmedabad high-speed rail corridor is an under-construction high-speed rail line connecting the cities of Ahmedabad, Gujarat and India's economic hub Mumbai, Maharashtra. It will be India's first high-speed rail line.
The construction of the corridor began on 14 September 2017 as scheduled and end by August 2022. The bullet train is scheduled to leave for its first run on 15 August, 2022.
Most of the corridor will be elevated, except for a 21 km underground tunnel between Thane and Virar, of which 7 km will be undersea.[24] The undersea tunnel was chosen to avoid damaging the thick vegetation present in the area.[25] The corridor will begin at the underground station in the Bandra-Kurla Complex in Mumbai, and then traverse 21 km underground before emerging above ground at Thane.
The line will have 12 stations. Proposed stations are Mumbai, Thane, Virar, Boisar, Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand and Ahmedabad, Sabarmati.[50] High speed rail stations will be constructed either above or next to existing railway stations to provide transfer with the Indian Railways network. The Director of the Railway Bureau of Japan's Ministry of Land, Infrastructure, Transportation and Tourism stated that "this makes construction extremely difficult".
