British Rail Class 67
class of 30 Bo′Bo′ diesel-electric locomotives
The Class 67 locomotives are a class of Bo-Bo diesel-electric locomotives that were built for the English Welsh & Scottish Railway (EWS) between 1999 and 2000 by Alstom at Meinfesa in Valencia, Spain with drive components (engine, generator and traction motors) from General Motors' Electro-Motive Division.
EMD's designation for this locomotive type is JT42HW-HS.
History
Design, testing and introduction
EWS ordered thirty locomotives via leasing company Angel Trains in a £45 million contract split between Alstom and Electro Motive Diesel, for use as Class 47 replacements for hauling high-speed Royal Mail trains and passenger trains. The locomotives were obtained on a 15-year lease from Angel Trains. At the end of the fifteen-year contract, ownership of the locomotives was transferred to DB Cargo UK.
The bodyshell is a monocoque load-bearing Alstom design, the bogies are an "H" frame Alstom design, the engine, traction motors and control electronics are GM-EMD products, and the same as used in the Class 66. Unlike the Class 66, the traction motors are frame mounted rather than axle hung to reduce unsprung mass and the gear ratio is increased allowing higher speeds. The cab design has a central driving position.
The locomotives are able to provide Electric Train Supply for passenger train heating and air-conditioning, and are equipped for both buffers and chain couplers and buckeye couplers, the latter attached by a swing arm mount.
High-speed running tests were undertaken with 67002 starting at Alstom's facility at La Sagra (Toledo, Spain) and running on the standard gauge Madrid-Toledo high-speed rail line. A top speed of 143 miles per hour (230 km/h) was obtained.
The first locomotive to be delivered was 67003, which arrived in October 1999.

Why this record matters
A short description can identify a subject without explaining its stakes. For “British Rail Class 67”, the useful work is to connect “class of 30 Bo′Bo′ diesel-electric locomotives” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 16, 2026. The linked authority identifier is Q2975732. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1999 and 2000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
