The Class 961 (961形) was a 6-car experimental Japanese Shinkansen train built in 1973.[1]
Contents |
The Class 961 train was developed to test new technology and design features to be incorporated in future high-speed trains for use on the planned Tōhoku Shinkansen and Jōetsu Shinkansen routes in the north-east of Japan. It featured motors in all six cars and was designed to cope with operations in the cold and snowy conditions of north-eastern Japan.
A number of interior accommodation configurations were tested, including a restaurant car, compartments, and sleeping berths.
The set, designated "S3", was formed as follows.[3]

The train was unveiled on 9 July 1973.[1]
From 17 July 1973, test running commenced on the Sanyō Shinkansen between Shin-Osaka and Himeji as a 4-car set.[4] Test running as a 6-car formation commenced on 1 August 1973 on the Tōkaidō Shinkansen between Hamamatsu and Nagoya.[4]
From 16 September 1974, the train was tested on the unopened section of the Sanyō Shinkansen between Okayama and Fukuyama, but the maximum speed was limited to 210 km/h (130 mph) due to opposition from lineside residents related to noise levels. The train was put into storage following the opening of the Sanyō Shinkansen extension in March 1975.[1]
On 11 May 1979, the Class 961 was transferred from storage at Ōi Depot in Tokyo (now JR Central's Tokyo No. 2 Shinkansen Depot) by road to the shinkansen depot at Oyama in Tochigi Prefecture for use on the "Oyama Test Track" section of the Tōhoku Shinkansen then under construction. Test running started on 5 June 1979, and the lettering "高速試験車" (High-Speed Test Train) was added to the nose section of the train from 9 June.[1]
On 7 December 1979, the Class 961 recorded a world speed record of 319 km/h (198 mph) on the Oyama Test Track, breaking the previous world record of 286 km/h (178 mph) set by the Class 951 Shinkansen in 1972.[5]
Following the opening of the Tōhoku Shinkansen in 1981, the Class 961's role as a test train ended, and it was stored at Sendai Shinkansen Depot. It was officially withdrawn on 10 August 1990.[3]
End cars 961-1 and 961-6 are preserved outdoors at Sendai Shinkansen Depot. These cars have been repainted into "Tōhoku Shinkansen" ivory and green livery.[6] A brass plaque commemorating the world speed record of 319 km/h (198 mph) set by this train in 1979 is displayed inside car 951-1 at Kokubunji in Tokyo.
