The JNR Class ED10 is a Japanese DC electric locomotive operated by the Japanese National Railways from 1922 to May 1960.
History[]
The ED10 is an early electric locomotive used on Japan's rail network. The locomotives were intended for use on the Tōkaidō Main Line in anticipation of its electrification.
Two locomotives were built in 1922; the locomotives's mechanical equipment was built by the Baldwin Locomotive Works while their electrical equipment was built by Westinghouse. They were originally classified as the Class 1000 and numbered 1000 and 1001, but were reclassified to Class ED10 when a rule regarding the standardization of locomotive names was enacted in 1928. Initially taking 600 or 1,200 V DC power from overhead, the locomotives were used on the Yamanote Line and Chūō Main Line; when their voltage was boosted to 1,500 V DC they were used on the Tōkaidõ Main Line and Yokosuka Line. ED10 1 was withdrawn from service in July 1959 and ED10 2 was withdrawn in May 1960. ED10 2 was resold to the Seibu Railway and reclassified as the Class E71, numbered E71; it was withdrawn in 1986 with the introduction of the Class E31 locomotives.
ED10 2, located at Seibu's Yokose Depot, is the only preserved ED10. It has been restored back to its original appearance as ED10 2 from E71.
Design[]
The ED10s featured large box-shaped bodies with large top-mounted headlights.
Specifications[]
The ED10s used a nose suspension drive system. MT5 traction motors were used on the locomotives.
