It was based on the 4100 type design imported from the Kingdom of Bavaria in 1912 (Meiji 45, Taisho era) and followed the same format in terms of basic function.
Five members of the class were converted to standard gauge and sent to Korea, Empire of Japan in 1939, four to the Pyeongbuk Railway and one to the Danpung Railway.[1] After the partition of Korea in 1945, these five were taken over by the Korean State Railway of North Korea. Their subsequent fate is unknown, but it was assumed they were scrapped between 1969 and 1976. Some 4110s were sent to Taiwan during the occupation period. In 1945, all were reclassified as EK900 by the Taiwan Railways. All of the EK900’s were scrapped between 1975 and 1980.
