Fastech 360S

Fastech 360 is the name given to a pair of former experimental high-speed trains 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 (223 mph), the target operational speed for production trains based on the new technologies. Speeds of up to 405 km/h (251 mph) were targeted during performance testing. Results of testing using these trains will be incorporated into the E5 series and E6 series trains which are scheduled to enter revenue service from 2011, eventually operating at 320 km/h (200 mph).
