The North London Line from Richmond to Broad Street, and later, to Stratford was the capital's Cinderella railway for many years. An official report in 2006 called it 'shabby, unsafe, unreliable and overcrowded.' It was threatened with closure under the Beeching Axe in the 1960s and again in the 1970s, escaping on both occasions due to organised and effective protest groups. Today it thrives as a key part of Transport for London's Overground network, and the story of how it survived closure threats and lack of investment is essential to an understanding of the politics of public transport in London over the past half century

Much writing about 19th-century East Africa has been distorted by the legacy of post-Enlightenment thought as well as by more insidious racist ideologies. Humanitarian lobbies throughout Western Europe, strongly influenced by positivist ideas, and campaigning to highlight the ravages of the slave trade, condemned Africa in their writings and propaganda to the periphery, outside universal history. Africa was reduced to a continent of slavery, in which the market, entrepreneurship and free wage labour could not exist. These ideas penetrated scholarly works and still survive in some guises. The consequence is that a variety of initiatives and forms of labour organization associated with the long distance trades in ivory and imported cloth have been overlooked by scholars, while the slave paradigm received widespread attention. Utilizing the conceptual tool of crew culture, Rockel documents a large-scale African migrant labour system. Nyamwezi caravan porters from the interior, as well as coastal Zanzibaris and Waungwana, forged a unique way of life in which market values and experience of wage labour and the caravan safari combined with customary standards and notions of honour derived from innovative reconceptualizations of tradition. The safari experience, commercial change, and interactions with peasant and pastoral communities along the trade routes, all contributed to the emergence of a unique East Africa modernity. This book can be read on a variety of levels It is a journey, a labour history, a story of African initiative and adaptation to modernity, and a contribution to a history of Tanzania and East Africa that gives due attention to intersocietal linkages, and networks.

Rockel utilizes a variety of methodologies and theoretical approaches derived from neo-Marxist and postcolonial perspectives, as well as Africanist innovations in oral historiography and labour and gender studies. Drawing on such insights, "Carriers of Culture" develops and expands our understanding of the way workers invent new and unique cultures to make sense of and control the labour process, create support networks including collective leisure activities, maximize and protect economic interests, and manage the labour market. The book is clearly written, and is illustrated with late-19th-century photographs and artwork.

Concern about the reduced availability and the increased cost of petroleum fuels prompted great efforts in recent years to reduce the fuel consumption of auto mobiles. The ongoing efforts to reduce fuel consumption have addressed many relevant factors, including increased engine performance, reduced friction, use of lightweight materials, and reduced aerodynamic drag. The results of the investigations assessing the various factors affecting fuel economy have been published in journals, conference proceedings, and in company and government reports. This proliferation of technical information makes it difficult for workers to keep abreast of aU developments. The material presented in this book brings together in a single volume much of the relevant materials, summarizes many of the state-of-the-art theories and data, and provides extensive lists of references. Thus, it is hoped that this book will be a useful reference for specialists and practicing engineers interested in the fuel economy of automobiles. J. C. HILLIARD o. S. SPRINGER vii CONTENTS 1.

This book deals with the golden age of the British motorcycle, featuring 100 machines shown in over 200 photographs. It offers a chronological survey of British motorcycles from the pioneers of 1900 through to the end of the 20th century. It features all the famous marques, such as AJS, Brough, BSA, Douglas, Greeves, Norton, Panther, Royal Enfield, Rudge, Scott, Sunbeam, Triumph, Velocette, Vincent and Zenith. Each entry includes information about the history of the bike, with specification panels detailing years in production, engine type, bore and stroke, capacity, gearbox, brakes, transmission, power, weight and top speed. From the beginning of the 20th century, the British motorcycle rapidly gained in reliability and sophistication. It began as a plaything of the leisured classes, until the war forced it into a utilitarian role. When peace returned in the 1920s, it was poised to fill a demand for mass transport, ushering in a golden age. Divided into four sections - The Pioneers, Vintage Days, The Classic Era, and Endings and Beginnings - this book profiles 100 of the best-loved machines that shaped a century of motorcycle design.It includes all the famous marques, each one illustrated with identification photographs, making it a book every bike enthusiast will want to own.

There are more than 400 miniature railways in Britain. Some are hidden away and privately owned, others are parkland attractions, and some - such as the Romney, Hythe and Dymchurch - are large commercial enterprises. They come in an array of gauges (from 5 inches up to 15 inches and sometimes beyond), but their most definitive characteristic is that they can carry passengers, whether sitting astride the rolling stock or inside enclosed carriages. In this colourfully illustrated guide, David Henshaw offers a concise history of miniature railways from the nineteenth century to the modern day, including a whistle-stop tour of the most notable examples open to the public - including the Ravenglass & Eskdale and Eastleigh Lakeside railways - exploring their layouts, engineering and rolling stock.

This volume contains the proceedings of a workshop held in Melbourne, Australia, entitled "Coupling of Fluids, Structures and Waves in Aeronautics". The 22 papers deal with new computational methods for multi-disciplinary design in aeronautics. They are grouped into chapters on fluids, structures, electromagnetics, optimisation, mathematical methods and tools, and aircraft design. Several papers treat coupling of these themes in a multi-physics setting. Included is a 17-page report of a Round Table discussion entitled "Future Tools for Design and Manufacture of Innovative Products in the Aeronautics Industry", together with a summary of important themes and issues. This research promotes the advanced technologies necessary for continued development of efficient and environmentally sustainable transport systems.
