JNR Class EB10

The JNR Class EB10 is a Japanese DC electric locomotive operated by the Japanese National Railways from 1927 to 1971.
==History==
The EB10 is an early electric locomotive used on Japan's rail network. The locomotives were intended for use on the a small portion of the Tōkaidō Main Line, known as the Suga Line, for switching purposes.
Two locomotives were built in 1927, initially as battery-electric locomotives; the locomotives's mechanical equipment was built by Kisha Seizō, their electrical equipment was built by Shibaura Seisakushō (now Toshiba) and their batteries were built by Yuasa Seisakushō (now GS Yuasa). They were originally classified as the Class 10 and numbered 10 and 11, but were reclassified to Class AB10 when a rule regarding the standardization of locomotive names was enacted in 1928. When introduced into service, the locomotives were based at Tabata Rolling Stock Depot, with the locomotives going back and forth on the short stretch of line; one locomotive would be active at a time, while the other remained in a shed adjacent to the line.
With the electrification of the Suga Line, the two AB10s were rebuilt in 1931 to Class EB10 locomotives, their most noticeable change being that they now take power from overhead lines. The locomotives were lent to the Tokyu Corporation in January 1946 for use on the Inokashira Line (now owned by Keio Corporation) due to a locomotive shortage, with the intent of using the locomotives in a push-pull formation; this idea was quickly abandoned when locomotive limits were found to have been breached. Another test run was conducted on what is now the Sotetsu Main Line but this was not pursued and the locomotives returned to JNR in June 1946. The locomotives were withdrawn in 1971 with the closure of the Suga Line.
EB10 1, located at Kyodonomori Park in Fuchū, Tokyo, is the only preserved EB10.
==Design==
The EB10s featured large box-shaped bodies with large top-mounted headlights.
==Specifications==
The EB10s used a nose suspension drive system. MT22A traction motors were used on the locomotives.
