The JGR Class 6400 (originally the JGR Class D12) was a 4-4-0 American-type steam locomotive operated by the Japanese Government Railways from 1902 to 1931.

History

The Class 6400 was an early steam locomotive operated in Japan. The type was ordered by the JGR, with eighteen locomotives manufactured at the American Locomotive Company in 1902. These were classified as the Class D12 locomotives and numbered 660 through 689.

The locomotives were reclassified as the Class 6400 in 1909 when a formal rule regarding standardized classification of locomotives was enacted; the locomotives were thus renumbered 6400 through 6429. The locomotives were mainly used in the Hamamatsu region but they were also used on the Tōkaidō Main Line hauling special express trains between Numazu and Nagoya; the locomotives were moved to the Kinki region in their later lives, serving the Kansai and San'in regions among others. Retirements began in 1930 and all were retired by 1931, with none sold to private railroads. No Class 6400s have been preserved.
