Originally intended to carry passenger and freight trains by day and night, the Shinkansen lines carry only passenger trains. The system shuts down between midnight and 06:00 every day for maintenance. The few overnight trains that still run in Japan run on the older narrow gauge network that the Shinkansen parallels. Compared with air transport, the Shinkansen has several advantages, including scheduling frequency and flexibility, punctual operation, comfortable seats, and convenient city-centre terminals. Shinkansen fares are generally competitive with domestic air fares. From a speed and convenience perspective, the Shinkansen's market share has surpassed that of air travel for journeys of less than 750 km, while air and rail remain highly competitive with each other in the 800–900 km range and air has a higher market share for journeys of more than 1,000 km.   Railways using Shinkansen technology are not limited to those in Japan. Taiwan High Speed Rail operates 700T Series sets built by Kawasaki Heavy Industries. The China Railways CRH2, built by CSR Sifang Loco & Rolling stocks corporation, with the license purchased from a consortium formed of Kawasaki Heavy Industries, Mitsubishi Electric Corporation, and Hitachi, is based on the E2-1000 series design. Class 395 EMUs were built by Hitachi based on Shinkansen technology for use on high-speed commuter services in Britain on the High Speed 1 line. Class 800 Bi-Mode trains were built by Hitachi for Great Western Railway and London North Eastern Railway. Class 801 EMUs were built by Hitachi for London North Eastern Railway. Class 802 Bi-Mode trains were built by Hitachi for Great Western Railway, TransPennine Express and Hull Trains. In 2014, it was announced that Texas Central Railway would build a ~300-mile (~480 km) long line using the N700 series rolling stock. The trains are proposed to operate at over 320 km/h (200 mph). In December 2015, India and Japan signed an agreement for the construction of India's first high speed rail link connecting Mumbai to Ahmedabad. Funded primarily through Japanese soft loans, the link is expected to cost up to $18.6b and should be operational in about 7 years. This followed India and Japan conducting feasibility studies on high-speed rail and dedicated freight corridors. The Indian Ministry of Railways' white-paper Vision 2020 submitted to Indian Parliament by Railway Minister Mamata Banerjee on 18 December 2009 envisages the implementation of regional high-speed rail projects to provide services at 250–350 km/h.
