An experimental shinkansen, or bullet train, in Japan was tested on Tuesday by the East Japan Railway Co. (JR East). This was ALFA-X's, as the shinkansen is called, first test ride since it was done in May 2019, per the Japan Times.
The Advanced Labs for Frontline Activity in rail eXperimentation, or ALFA-X, can reach a maximum speed of 248 mph (400 km/h), and on Tuesday it hit 237 mph (382 km/h).
Tuesday's successful test run happened on JR East's Tohoku Shinkansen line, which links Tokyo and Aomori Prefecture. It went from Sendai and Morioka stations in around 40 minutes, a trip that usually takes an hour and 15 minutes.
