The Class EF60 (EF60形?) was the first Japanese second-generation DC electric locomotive type with six driven axles (classes EF60 to EF67), and the first versions used the same MT49 390 kW traction motors as the ED60 and ED61 designs. A total of 143 locomotives were built between 1960 and 1964 by Kawasaki, Tōshiba, Tōyō & Kisha, and Mitsubishi. The class was split between 129 freight locomotives (classified EF60-0) designed to supersede the mammoth EH10s on Tōkaidō and Sanyō Main Line freight, and 14 passenger locomotives (EF60-500) to replace EF58s on sleeping car trains on the Tōkaidō and Sanyō Mainlines.
The third-batch build of locos (EF60 84 to 129 and EF60 512 to 514) had up-rated traction motors and differed slightly in having twin headlamps (like the EF65 and other later types) rather than the single large headlamp on earlier versions. Unlike the ED60s, these locos were designed to operate singly rather than in pairs, and so cab-end gangway doors were not included. The EF60-0s initially appeared in the standard all-over brown livery, but were repainted into blue from 1965 onward.
The role of the EF60-500s at the head of the premier Blue Trains was short-lived, however, with the arrival of more powerful EF65s in 1965, and they too found themselves transferred to freight duties. From the late 1970s, EF60s were to be seen on the Chūō, Takasa
