Book Description
When British Railways initiated its Modernization Plan in 1955, its Western Region elected to trial locomotive designs with hydraulic transmission whilst BR encouraged designs with electric transmission. The Western Region felt that the lighter weight of 78 tons for a diesel hydraulic locomotive producing 2000 hp, compared to an equivalent weight of 132 tons for a diesel electric locomotive producing 2000 hp, would better meet BR's requirement for a modern locomotive. BR's failure to follow up with its declared policy of having all freight vehicles fitted with brakes saw operators preferring the heavier diesel electric designs which proved more able to operate trains without through brakes at higher speed. The greatest concern was with operating costs whereby the Western Region policy of replacing components at the depot then transferring them to Swindon for repair incurred heavy costs that were reflected in the maintenance cost per locomotive. Given the smaller number of diesel hydraulic locomotives and the larger number of diesel electric locomotives it was little surprise that by the mid-1960s a cost comparison showed that the build and operation of diesel electric locomotives was increasingly cheaper over the long term. Furthermore the increased availability of diesel electric locomotives released by a combination of factors provided an opportunity to replace the diesel hydraulic fleet, which was withdrawn from service during the 1970s. The preservation of redundant locomotives was slow but once it was confirmed, by the preservation of 'Hymek' Class 35 D7017 in 1975, that public appeals could quickly fund the preservation of withdrawn examples further public appeals followed. In a short space of time 31 locomotives from a mixed fleet of 358 locomotives entered preservation to remind both enthusiasts and the public of a concept (i.e. hydraulic transmission) that had had much to offer but had been dismissed on questionable financial grounds.

Book Description
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

British Diesel Locomotives of the 1950s and ‘60s

British Diesel Locomotives of the 1950s and ‘60s PDF Author: Greg Morse

Pages : 64

Book Description
After the Second World War, the drive for the modernization of Britain's railways ushered in a new breed of locomotive: the Diesel. Diesel-powered trains had been around for some time, but faced with a coal crisis and the Clean Air Act in the 1950s, it was seen as a part of the solution for British Rail. This beautifully illustrated book, written by an expert on rail history, charts the rise and decline of Britain's diesel-powered locomotives. It covers a period of great change and experimentation, where the iconic steam engines that had dominated for a century were replaced by a series of modern diesels including the ill-fated 'Westerns' and the more successful 'Deltics'--iconic trains of the era.

Technology, Politics, And Society In China

Technology, Politics, And Society In China PDF Author: Rudi Volti
Publisher: Routledge
ISBN: 1000314251
Category : Political Science
Languages : en
Pages : 255

Book Description
This study is the first to summarize the major technological policies implemented in China since 1949 and to place them in their social and historical context. Dr. Volti looks at technological change in China as part of a broader process of economic, political, cultural, and organizational change, focusing primarily on four key areas—agriculture, energy, ground transportation, and medicine and public health. He emphasizes how technological change has been shaped by political and ideological structures, notes how China’s unique cultural heritage has affected adoption of technologies developed outside China, and assesses China’s success in developing technologies appropriate to its specific needs as an economically and politically developing nation. He draws on interviews with technicians engaged in the transfer of technology to China as well as extensive primary source materials.
