Central Japan Railway Co. (JR Tokai) plans to raise the 270 kph speed limit on the Tokaido Shinkansen Line, President Yoshiomi Yamada said.

The railway plans to let its new N700A bullet train run faster than 270 kph by spring 2015, but Yamada said Thursday that a new speed limit hasn’t been set yet.

The fastest line in Japan now is the Tohoku Shinkansen Line run by East Japan Railway Co. (JR East), which has a maximum speed of 320 kph, followed by the Sanyo Shinkansen Line run by West Japan Railway Co. (JR West), which tops out at a speed of 300 kph.

JR Tokai, which hasn’t raised the speed limit on its line since 1992, can whisk commuters between Tokyo and Shin-Osaka stations in two hours, 25 minutes.

That’s about to shrink, Yamada said.

“We would like to shorten the time as much as possible and improve our train service,” he said.

JR Tokai plans to ask the transport ministry to approve the speed hike next year.

The N700A debuted in February with an advanced braking system. The N700 series is currently being upgraded to install the new systems.
