The JNR Class EF14 was a Japanese DC electric locomotive operated by the Japanese National Railways from 1931 to 1974.
History[]
The EF14 was spawned from the EF52 locomotives that were manufactured as one of Japan's first domestic passenger electric locomotives produced in volume. Initially constructed in 1931 as EF52 8 and EF52 9, the locomotives featured similar performance to the EF53 introduced the next year and can be considered their forerunners.
As their performance was significantly higher than the EF52s, they were reclassified as the Class EF54 in 1932. Initially used to pull fast passenger trains on the Tōkaidō Main Line, they were rebuilt to pull freight trains with the onset of the Pacific War to cope with the increasing demand for freight transport. Both locomotives were rebuilt at Hamamatsu Works; EF54 1 was rebuilt in 1944 and EF54 2 in 1945 to become EF14 1 and 2. Assigned to the Chūō Main Line, the EF14s were used to pull freight trains, although its traction was lower than other locomotives. From 1960, they became switching locomotives at Osaka Station until they were withdrawn in 1974.
No EF14s have been preserved.
Design[]
The EF14s featured large box-shaped bodies with large top-mounted headlights.
Specifications[]
The EF14s used a nose suspension drive system. MT17 traction motors were used on the locomotives. Compared to the EF52s they were based on they featured different traction motors with lower gear ratios.
