Fastech 360
Fastech 360 is the name given to a pair of former experimental high-speed EMU trainsets developed by East Japan Railway Company (JR East) to test technology for the next-generation Shinkansen rolling stock. The name is a portmanteau of Fast, Technology, and 360 km/h (360 km/h or 225 mph), the target operational speed for production trains based on the new technologies.
