Operations
Class DF50 locomotives were intended for use on both passenger and freight services, and included a steam generator for train heating.[3] They operated on the following lines, including use hauling "Blue Train" sleeping car services.[2]
In later years, operations were restricted to Kyushu and Shikoku, with the remaining locomotives withdrawn in 1983, except for DF50 1, which later passed into JR Shikoku ownership.[1]

The locomotives were initially painted in all-over maroon with stainless steel bands, but were subsequently repainted into the standard JNR diesel locomotive livery of vermillion and grey.[2]
