The Class 951 train was a two-car unit formed of cars numbered 951-1 and 951-2. Car 951-1 was built by Kawasaki Sharyo (present-day Kawasaki Heavy Industries), and had a seating capacity of 40 with seats arranged 3+2 abreast. Car 951-2 was built by Nippon Sharyo, and had a seating capacity of 50, also with seats arranged 3+2 abreast.[1]
Both cars were fitted with a cross-arm type pantograph at the inner end.[1] Both were based on the PS200 type used on the 0 Series Shinkansen trains, but the pantograph on car 951-1 was designated PS9010K, and that on car 951-2 was designated PS-1010A.[1] Normally, only the pantograph on car 951-2 was used.[1]
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The train was formally withdrawn on 11 April 1980.[4] Car 951-2 was transferred to the Railway Technical Research Institute in Kokubunji, Tokyo, where it was used for roller rig testing.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.[5] Car 951-2 was subsequently stored out of use inside the Railway Technical Research Institute,[1] and was cut up in 2008.[4]
