JNR C10 Class Steam Locomotive

C10 8 preserved steam locomotive at Oigawa Railway
C10 8 — 1976, Rasa Industry Miyako works

23 of these locomotives were manufactured in 1930 by Kisha Seizo and Kawasaki to modernize transportation through replacing aging locomotives of miscellaneous types that had been used in urban and suburban sections. However, as suburban areas were gradually electrified, the locomotives were moved to regional lines. Due to the heavy weight of the locomotive body, it was gradually replaced by the new type C11, and was used until 1963 for shunting (moving locomotives inside stations and train yards). Later, the C10 8 (pictured above) was sold off to the Rasa Industries Miyako works, and was used to transport raw materials and products within the factory until 1979, becoming the last steam locomotive of the National Railways type to remain in active service. Today this locomotive is being preserved dynamically (refers to locomotives that have been preserved in a ready-to-operate state, and/or are still running today) at Oigawa Railways.
