JNR Class DD51

Locos numbered from DD51 501 to 799 and from 1001 to 1186 were equipped to operate in multiple, and locos numbered DD51 800 to 899 and 1801 to 1805 were built without steam generators for train heating. ==Liveries==

All locomotives numbered from DD51 2 onwards were finished in the standard diesel livery of orange/red with grey upper surfaces separated by a white stripe. Re-engined locos operated by JR Freight in Hokkaido sport a livery based on the Class DF200 colour scheme, with no white stripe. These locomotives were used in pairs double-heading freight trains. JR Hokkaido locos were all finished in the "Hokutosei" livery of blue with a gold stripe and shooting star logo. These were used in pairs for hauling sleeper trains (Hokutosei, Cassiopeia, and Twilight Express) between Hakodate and Sapporo.
