The Class EF67 is a class of electric locomotives operated by Japan Freight Railway Company (JR Freight) as dedicated banking locomotives on the steeply-graded "Senohachi" section of the Sanyō 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]

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.[2] 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.[2]

Conversion details[edit]

The EF67-0s were converted as shown below.[3]

Number Former number Built Rebuilt
EF67 1 EF60 104 30 September 1964 31 March 1982
EF67 2 EF60 129 27 October 1964 30 January 1984
EF67 3 EF60 88 9 July 1964 25 December 1986

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.

Conversion details[edit]

The EF67-100s were converted as shown below.[3]
