In 1957 the Western Region of BR identified a need for 400 Type 1 diesel locomotives for short-haul freight duties but it was 1964 before the first was introduced. General-purpose Type 1s were being delivered elsewhere but WR management regarded these as too expensive for their requirements. After completion of design work on the Western' locomotives, Swindon turned to creating a cheap no-frills' Type 1\. At 65% of the cost of the Bo-Bo alternative, the Swindon 0-6-0 represented a better fit' for the trip-freight niche. Since 1957 the privatised road-haulage industry had decimated BR's wagon-load sector; whilst the 1962 Transport Act released BR from its financially-debilitating public-service obligations, the damage had been done, and the 1963 Beeching Plan focused on closing unprofitable routes and associated services. By 1963 the original requirement for 400 Type 1s had been massively reduced. Fifty-six locomotives were constructed in 1964/65\. Continuing traffic losses resulted in the whole class becoming redundant by 1969\. Fortuitously, a demand for high-powered diesels on the larger industrial railway systems saw the bulk of the locomotives finding useful employment for a further twenty years. This book covers the life of these locomotives on British Railways; a companion volume will provide an extensive appraisal of "Their Life in Industry" for the forty-eight locomotives which made the successful transition after withdrawal from BR

This book provides an in-depth history of the Metropolitan-Vickers diesel-electric Type 2 locomotives, more frequently known collectively as the Co-Bo's due to their unusual wheel arrangement. Twenty locomotives were constructed during the late-1950s for use on the London Midland Region of British Railways. The fleet was fraught with difficulties from the start, most notably due to problems with their Crossley engines, this necessitating the need for extensive rehabilitation work during the early-1960s. Matters barely improved and the option to completely re-engine the locomotives with English Electric units was debated at length, but a downturn in traffic levels ultimately resulted in their demise by the end of 1968 prior to any further major rebuilding work being carried out. Significant quantities of new archive and personal sighting information, supported by over 180 photographs and diagrams, have been brought together to allow dramatic new insights into this enigmatic class of locomotives, including the whole debate surrounding potential re-engining, their works histories, the extended periods in storage, together with in-depth reviews of the various detail differences and liveries.

The 'Claytons' were originally conceived as the British Railways "standard" Type 1 diesel-electric locomotive, superseding other Type 1 classes delivered as part of the 'Pilot Scheme' fleet. The early classes suffered from poor driver visibility, and the plan from 1962 was for subsequent trip-freight and local yard shunting locomotives to be centre-cab machines with low bonnets to dramatically improve visibility. To this extent the Claytons were highly successful and popular with operating crews. However, the largely untested high-speed, flat Paxman engines proved to be highly problematical, resulting in deliveries being curtailed after 117 locomotives. Further requirements for Type 1 locomotives after 1965 were met by reverting to one of the original 'Pilot' designs! Deteriorating traffic levels ultimately led to the Claytons being withdrawn from BR service by December 1971. Considerable amounts of archive material have been unearthed to enable the issues surrounding the rise and fall of the 'Standard Type 1' locomotives to be fully explored. Further sources provide insights into the effort and money expended on the Claytons in a desperate attempt to improve their reliability. Individual locomotive record cards, together with personal sighting information, allow histories of each class member to be developed including allocations, works visits, liveries and disposal details. Supported by over 280 photographs and diagrams, dramatic new insights into this troubled class have been assembled for both historians and modellers alike.
