The Class EF67 is a retired class of electric locomotives operated by Japan Freight Railway Company (JR Freight) as dedicated banking locomotives on the steeply-graded "Senohachi" section of the Sanyo Main Line between Seno and Hachihonmatsu. The class is subdivided into three EF67-0 locomotives converted between 1982 and 1984 from former Class EF60 locomotives, and five EF67-100 locomotives converted in 1990 from former Class EF65 locomotives.[1]

With the introduction of the Class EF210-300 from 2013, the Class EF67 fleet was gradually withdrawn, with the last unit, EF67 105, being withdrawn from regular service in February 2022.[2]

EF67-0

[edit]

Three EF67-0s were built from former 4th-batch Class EF60 locomotives from 1982 for use banking freight trains over 1,000 tonnes, for which the former EF61-200 banking locomotives were unsuitable. The No. 1 end was modified with a gangway door and access platform.[1] The locomotives were painted in an all-over orange livery (officially "Red No. 11") with yellow strips below the cab windows.[3] These three locomotives are fitted with PS22D scissors-type pantographs.[1]

The EF67-0s were equipped with an automatic uncoupling mechanism at the No. 1 end to enable the banking locomotives to be uncoupled on the fly, but uncoupling while in motion was discontinued from the start of the 22 March 2002 timetable revision.[3]

Following the introduction of the Class EF210-300 in 2013, EF67 2 and 3 were withdrawn, with EF67 1 following in 2014. As of April 2022, EF67 1 is preserved at Hiroshima Depot.[2]

EF67-100

[edit]

Five EF67-100s were built from former 6th-batch Class EF65-0 locomotives from 1990 to replace the ageing EF61-200 banking locomotives. The EF67-100 fleet was refurbished between 2003 and 2004, and repainted into a revised livery with grey and white lines along the lower body side.[1] These locomotives were originally fitted with PS22B scissors-type pantographs, which were replaced with single-arm pantographs on refurbishment, but these were subsequently returned to PS22B scissors-type pantographs.

EF67 103 and 104 were scrapped in 2016, and 101 and 102 were scrapped in 2020.[2]: 3  The last EF67 in operation, EF67 105, was withdrawn from regular service in February 2022,[5] and operated a commemorative final-run service on 29 March of that year.[6]
