British Rail Class 67 diesel‑electric locomotives
Overview of the British Rail Class 67: a late‑1990s diesel‑electric Bo‑Bo locomotive type built by Alstom under subcontract, its characteristics, history, roles and notable facts.
Overview
The British Rail Class 67 is a family of high‑speed diesel‑electric locomotives introduced at the turn of the 21st century. Manufactured in Spain under subcontract to a North American company, they were intended to provide faster, more reliable traction for a mix of mail, parcel, passenger and charter work across the UK rail network. The type is noted for its relatively modern bodywork and higher gearing for sustained higher speeds than many conventional freight locomotives.

Design and characteristics
Class 67s are four‑axle (Bo‑Bo) diesel‑electric locomotives. Their basic layout pairs a diesel engine driving an electrical generator with individual traction motors on each axle. Key practical characteristics include improved suspension and bogie design to support higher speed running, provision of electric train heating or head‑end power for passenger trains, and cab features aimed at driver visibility and comfort.
- Wheel arrangement: Bo‑Bo (four axles, two bogies)
- Powertrain: diesel engine coupled to electrical traction motors
- Equipment: designed for both passenger and fast freight roles
History and development
The series was built between 1999 and 2000 by Alstom's works in Valencia under subcontract from a Canadian manufacturer. The order arose from a need in the late 1990s to renew motive power used on express freight and passenger duties and to give operators a locomotive able to sustain higher line speeds with heavy trains. Since their introduction, individual locomotives have been operated by several UK freight and passenger companies; some have spent time on charter and special train work.
Service roles and examples
Class 67 locomotives have been used in a variety of duties where speed and reliability matter. Typical uses include:
- Express mail and parcel services, where fast transit times are required.
- Passenger charter trains and rescue duties for failed sets.
- Occasional scheduled passenger workings where diesel traction is required.
Notable facts and references
Construction of the Class 67 fleet illustrates a late‑1990s pattern of international subcontracting in locomotive manufacture. For manufacturer and build information see the manufacturer page: Alstom / builder details, and for additional production records consult the builder's subcontractor listing: production and subcontract information. Over time the class has become a familiar sight on specialist and operationally important workings across the UK rail network.
