Design
Manufacture of the train was shared among four different manufacturers, with a number of different body construction methods used. The two ends cars employed differing nose designs, and a number of pantograph shroud designs were tested over the lifetime of the trainset.[2]

History
"300X" trainset on a daytime testrun at Maibara Station, July 1999The train was unveiled on 22 December 1994[4]
Test-running on the Tōkaidō Shinkansen was delayed by track damage caused by the Great Hanshin earthquake in January 1995, but full-scale test-running commenced on 25 May 1995, between Maibara and Kyoto.[4]
On 21 September 1995, the Class 955 train recorded a maximum speed of 354.1 km/h (220.0 mph) on the Tōkaidō 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 by JR East's Class 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 Tōkaidō Shinkansen between Maibara and Kyoto.[3] This record still stands as of May 2011.
The Class 955 trainset was officially withdrawn on 1 February 2001.[6]
Preservation
Car 955-1 preserved at Maibara, July 2006End car 955-1 is preserved outdoors at the RTRI large-scale wind tunnel test facility in Maibara, Shiga.[7] End car 955-6 was initially preserved inside JR Central's Hamamatsu Works, and was moved to the new SCMaglev and Railway Park in 2010.[8]
