Central Japan Railway Co. (JR Tokai) will locate stations for a magnetic-levitation line in Tokyo's Shinagawa area and near Nagoya's bullet train station.

The railway also plans maglev stops in Sagamihara, Kanagawa Prefecture, near Kofu, Yamanashi Prefecture, and near Nakatsugawa, Gifu Prefecture, along the 286-km route, Atsushi Honda, a planning manager, said Tuesday in Tokyo.

JR Tokai aims to spend ¥5.1 trillion to build a line that slashes travel time between Tokyo and Nagoya to as little as 40 minutes, less than half that of current bullet trains. The maglev line will run as fast as 500 kph, said Shin Kaneko, an executive director at the company.

The environmental assessment for the line will take about three years and work on the line will begin in the year starting in April 2014, Kaneko said. The railway is already extending an existing maglev test track in Yamanashi Prefecture to 42.8 km, which will become part of the line.
