The Class EF500 (EF500形) was a prototype Bo-Bo-Bo wheel arrangement multi-voltage AC/DC electric locomotive formerly operated by JR Freight in Japan.[1]
Intended as a prototype for a new fleet of high-power electric locomotives to haul freight trains northward from Tokyo to Hokkaido, the sole member of the class, EF500-901, was built jointly by Kawasaki Heavy Industries and Mitsubishi Electric, and delivered to Shin-Tsurumi Depot in August 1990.[2] The design was broadly based on the Class EF200 locomotives built for Tokaido Main Line freight duties west of Tokyo.[2] Following initial test-running, the locomotive underwent long-term feasibility testing on freight services on the Tohoku Main Line.[2] However, the locomotive fell foul of newly introduced government guidelines covering high-frequency electromagnetic noise emissions, and so fleet production was deemed unfeasible.[2] JR Freight instead opted for the Class EH500 and Class EF510 locomotive designs.[2]
EF500-901 was transferred to Sendai Depot in 1996, but subsequently saw little use.[2] It was formally withdrawn on 29 March 2002.[3] The locomotive is stored at JR Freight's Hiroshima Depot.[4]
