The Class ED74 (ED74形) was a Bo-Bo wheel arrangement AC electric locomotive type operated by Japanese National Railways (JNR) in Japan between 1962 and the 1980s.^[1]

Design

The Class ED74 was developed as a four-axle version of the six-axle (

Class EF70 electric locomotives introduced a year earlier on the Hokuriku Main Line, and was intended for use on services north of Fukui where the gradients were easier.^[2]

History

A total of six locomotives were built by Mitsubishi in 1962, coinciding with the electrification of the Hokuriku Main Line between Fukui and Kanazawa.^[1]^[3] The six locomotives were delivered to Tsuruga Depot.^[3]

Displaced by the arrival of

Oita, as well as on overnight sleeping car services that did not require a separate heating supply from the locomotive.^[2] Despite electrification south to Miyazaki in 1974, the Class EF74 locomotives were not allowed south of Oita due to their axle load, and were subsequently replaced by an additional build of Class ED76 locomotives.^[2] The entire class was withdrawn by 1982.^[2]

Classification

The ED74 classification for this locomotive type is explained below.

E: Electric locomotive
D: Four driving axles
7x: AC locomotive with maximum speed exceeding 85 km/h (55 mph)
