The Chūō Shinkansen (中央新幹線) is a planned Japanese maglev line designed to ultimately connect Tokyo, Nagoya, and Osaka.
The line is intended to be built by extending and incorporating the existing Yamanashi test track (see below). An initial extension of the track from its present length of 18.4 km to 42.8 km is currently under construction.[1]
The line is expected to connect Tokyo and Nagoya in the first stage in
40 minutes, and eventually Tokyo and Osaka in an hour, running at a
maximum speed of 505 km/h.[2]
The Chūō Shinkansen is the culmination of Japanese maglev development
since the 1970s, a government-funded project initiated by Japan Airlines and the former Japanese National Railways (JNR). JR Central now operates the facilities and research.
The trainsets themselves are popularly known in Japan as Linear Motor Car (リニアモーターカー rinia mōtā kā), though there have been many technical variations.
Government permission to proceed with construction was granted on May
27, 2011. Construction of the line, which is expected to cost over ¥9 trillion, is expected to commence in 2014.[3]
JR Central aims to begin commercial service between Tokyo and Nagoya in
2027, with the Nagoya-Osaka section to be completed in 2045.[4] JR Central is considering opening up partial maglev service between Kofu, Yamanashi and Sagamihara, Kanagawa around 2020.[5]
