The Class ED15 (ED15形) was an electric locomotive formerly operated in Japan from 1924 until 1960.[1] The Class ED15 was the first mainline electric locomotive type to be built domestically in Japan.[1]

History

Founder Namihei Odaira and other engineers from Hitachi visited the Omiya Works of the Japanese Governmental Railways in 1922 and saw imported electric locomotives. They decided to build one by themselves soon afterwards, and the first example, ED15 1 was completed in 1924.[2] Two more locomotives of the class were built in 1926.[1] Initially designated Class 1070 under the original Japanese Government Railways (JGR) numbering scheme, the locomotives became Class ED15 from 1928.[1]

The locomotives were initially used on Tokaido Main Line freight services, and were later employed on the Chuo Main Line.[1]

The locomotives were withdrawn from service between 1959 and 1960.[1]

Preservation

ED15 1 is preserved at the Hitachi Mito Factory in Hitachinaka, Ibaraki.[1]
