Class C52

1925 - 1947

Imported for research purposes as a three-cylinder large Tender-Engine.

Six of the three-cylinder model class C52s (it was named 8200 and was later changed to C52) were imported from US ALCO (American Locomotive Co.) in 1925. These were imported for the purpose of research in regard to three-cylinder type engines and other new technology.
An engine was imported, and the tender was made in a Japanese factory. Six engines represented a very low number and was not good business from ALCO's standpoint. ALCO expected more orders, but, only six engines were made. C52 not only had three-cylinders, but other new technology as well. These were helpful in regard to future domestic product engine design.

After their appearance, they went into service on the Tokaido main line as express trains. C52s increased their pulling capacity by 20% from the domestic model C51. But the domestic three-cylinder model C53 later appeared, and since there were only six C52s, the importation of foreign parts represented problems. Another problem was, C52's driving wheel diameter of 1,600mm was not satisfactory for Japanese passenger trains or even freight trains.

Afterward, all the C52s were moved to Seno depot on the Sanyo line, for assisting at Seno-Hachi Pass. And lastly, they were moved to yard work at Shimonoseki yard during WW2. C52s were not used after the war, and after Jun 25 1947, all C52s were scrapped.
