JNR D60 Class Steam Locomotive
The type D60 was made from the type D50, which had limited areas it could be used because of its heavy body, by changing the single-axle bogie to a two-axle, and the axle arrangement from 2-8-2 to 2-8-4. This lightened its axle weight, and as a result, it was able to enter lower grade lines. It was created by converting a total of 78 D50s at the Japan National Railways (JNR) Nagano, Hamamatsu, and Tsuchizaki factories between 1951 and 1956. They were used for freight on regional lines in various locations, and were last used in Kyushu until 1973. Currently, 4 of them are in static preservation.
