The Class 951 (951形?) was an experimental Japanese Shinkansen train built to test the technology for future high-speed trains operating at speeds of up to 250 km/h (155 mph) following the opening of the Tokaido Shinkansen in 1964.[1][2]

The train was unveiled to the press on 26 March 1969, with formal test running commencing on the Tōkaidō Shinkansen from 2 July 1969.[3]

On 24 February 1972, the Class 951 recorded a world speed record of 286 km/h (178 mph) on the Sanyo Shinkansen between Himeji and Nishi-Akashi, breaking the previous record of 256 km/h (159 mph) set by the Class 1000 Shinkansen.[1]

The train was formally withdrawn in April 1980, and transferred to the Railway Technical Research Institute in Kokubunji, Tokyo, where it was used for roller rig testing. Car 951-1 was donated to the nearby Hikari Plaza Community Centre in 1994, where it is open to the public.[4] Car 951-2 is stored out of use inside the Railway Technical Research Institute.[1]
