The Class DF50 (DF50形) is a class of Bo-Bo-Bo wheel arrangement diesel-electric locomotives operated by Japanese National Railways (JNR) in Japan from 1957 until 1983. [1]
The first batch of 65 locomotives was built between 1957 and 1962 with Sulzer 8-cylinder 8LDA25A 1,060 hp diesel engines. [1] [2] Production was shared between Kisha Seizō, Mitsubishi, and Nippon Sharyō. [2]
A later batch of 73 locomotives was built between 1958 and 1963 with MAN V6-cylinder V22/30 1,200 hp diesel engines. [1] [2] Production was shared between Hitachi, Kawasaki, and Toshiba. [2]
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In later years, operations were restricted to Kyushu and Shikoku, with the remaining locomotives withdrawn in 1983, except for DF50 1, which later passed into JR Shikoku ownership.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]
Three Class DF50 locomotives were preserved. [3]
The DF50 classification for this locomotive type is explained below.
