The is a high-speed maglev train that the Central Japan Railway Company (JR Central) is developing and testing. JR Central plans to use the L0 series on the Chūō Shinkansen railway line between Tokyo and Osaka, which is under construction. The L0 series uses the Japanese-designed SCMaglev system. Mitsubishi Heavy Industries and Nippon Sharyo, a subsidiary of JR Central, are building fourteen pre-production vehicles. A seven-car train set a land speed record for rail vehicles of on 21 April 2015. The trains are planned to run at a maximum speed of , offering journey times of 40 minutes between Tokyo (Shinagawa Station) and , and 1 hour 7 minutes between Tokyo and Osaka. Specifications The end cars of L0 series trainsets are long and carry 24 passengers. The nose extends for better aerodynamics and reduced noise in tunnels. Intermediate cars are long and carry 68 passengers each, which totals a long and 728 passengers train. Each row is four seats wide, one less than JR Central shinkansen trains. The cars are more box-shaped than earlier models to allow for more interior space. Cars are painted white and blue. During normal operation, the train is expected to operate at a maximum speed of . The train does not require a driver, but does have a camera at the front of both end cars in order to allow for remote operation, in case the automated systems fail. The camera is more apparent on the revised end cars, introduced in 2020. It is moved to a higher position, and increased in size. The superconducting magnets in the bogies are built by Toshiba and Mitsubishi Electric. The cars are built by Nippon Sharyo, with Mitsubishi Heavy Industries also having built some in the past. Mitsubishi Heavy Industries stopped producing cars in 2017 after car manufacturing cost disagreements with JR central and the Mitsubishi SpaceJet's spiralling development costs. The bogies are arranged in a Jacobs bogie configuration. Planned operations Chuo Shinkansen Construction on the Chuo Shinkansen line on which the train is intended to run began in December 2014. The first section to Nagoya is expected to be completed in 2027. That section will be approximately 85% tunnels with an estimated cost of ¥5.5trillion (US$46.5billion). The relatively high cost is in large part due to the many tunnels. The complete line to Osaka is estimated to cost ¥9trillion ($74.7billion), and was expected to be completed
