The train was unveiled on 22 December 1994.[4]
Test-running on theTōkaidō Shinkansenwas delayed by track damage caused by theGreat Hanshin earthquakein January 1995, but full-scale test-running commenced on 25 May 1995, betweenMaibaraandKyoto.[4]
On 21 September 1995, the Class 955 train recorded a maximum speed of 354.1 km/h (220.0 mph) on the Tokaido Shinkansen between Maibara and Kyoto.[5]
On 11 July 1996, the train recorded a maximum speed of 426.6 km/h (265.1 mph), exceeding the previous national speed record of 425.0 km/h (264.1 mph) set in December 1993 byJR East'sClass 952/953 "STAR21"experimental train.[5]
On 26 July 1996, the train recorded a Japanese national speed record of 443.0 km/h (275.3 mph) on the Tokaido Shinkansen between Maibara and Kyoto.[3]This record still stands.
The Class 955 trainset was officially withdrawn on 1 February 2002.[6]
Preservation
[edit]End car 955-1 is preserved outdoors at the RTRI large-scale wind tunnel test facility inMaibara, Shiga.[7]End car 955-6 was initially preserved inside JR Central's Hamamatsu Works, and was moved to the newSCMaglev and Railway Parkin 2010.[8]
