"WIN350" was the name given to the 500-900 series (500系900番代?) 6-car experimental high-speed Shinkansen train developed in 1992 by the West Japan Railway Company (JR West) in Japan to test technology to be incorporated in next-generation shinkansen trains expected to operate at speeds of 350 km/h (217 mph) from 1994.[2] Initially given the designation "500X", the name "WIN350" stood for "West Japan's Innovation for operation at 350 km/h".[3]


Cars 500-901 to 500-903 were built by Kawasaki Heavy Industries in Hyogo Prefecture. Cars 500-904 to 500-906 were built by Hitachi in Yamaguchi Prefecture.[4]

The front-end designs of the two driving vehicles (500-901 and 500-906) were slightly different, with 500-906 featuring a "cockpit" style arrangement.[3] The external livery was purple and light grey, with darker purple lining.

All axles were motored, using 300 kW three-phase motors, and cars were equipped with tilting and active suspension.[3]

Internally, only car 4 was fitted with passenger seats, with 10 rows of 3+2 standard-class seating and 5 rows of 2+2 Green class (first class) seating.[5]


The 6-car set, designated "W0", was formed as follows.[6]

Car No. 1 2 3 4 5 6
Designation M'1c M'1p M1 M2 M'2p M2c
Numbering 500-901 500-902 500-903 500-904 500-905 500-906

Initially, cars 1, 2, and 5 were fitted with pantographs.[5]


The WIN350 train was delivered to Hakata Shinkansen Depot in April 1992.[4]

On 6 August 1992, the train recorded a Japanese national speed record of 345.8 km/h on the Sanyo Shinkansen.[3] Two days later, on 8 August 1992, the train recorded a Japanese national speed record of 350.4 km/h on the Sanyo Shinkansen between Ogōri (now Shin-Yamaguchi) and Shin-Shimonoseki.[2]

The WIN350 trainset was withdrawn on 31 May 1996, and a special farewell ceremony was held at Hakata Shinkansen Depot.[2][3]


End car 500-901 is preserved outdoors at the RTRI large-scale wind tunnel test facility in Maibara, Shiga. Initially expected to be moved to the Modern Transportation Museum in Osaka,[3] car 500-906 is preserved at Hakata Shinkansen Depot.[7]
