THIS standard treatise on mechanical railway signalling by Leonard Lewis was written at the turn of the twentieth century. Originally published in 1910 as Railway Signal Engineering (Mechanical), a second edition followed in 1912. A third edition, revised and enlarged by J. H. Fraser, appeared in 1932. Since its original publication, now more than 100 years ago, much if not all of the mechanisms and practices described and illustrated have disappeared from the modern high-speed railways of Britain and the rest of the world. In his preface to the first edition, Lewis wrote that he intended the book to be '... suitable for men who are engaged in railway work, but not necessarily in connection with the Signalling Engineer's Department.' Today, such men no longer have any professional interest in what to them is now archaic and superseded. However, with the popular growth of preserved heritage railways, and the dedicated reconstruction and re-creation of many railway artefacts by enthusiasts, it is no longer possible to state categorically that any particular mechanism or operating procedure described in the book is extinct. Although they may have disappeared from modern railways in the electronic and computer controlled age, original or replica items or otherwise obsolete methods of working may well be in regular use on preserved branch line railways or be on display in railway museums. Herein lies the main inspiration for this new edition at the start of the twenty first century. Lewis's book, once describing the very cutting edge of railway technology, has become with the passage of time a valuable work of history. Nevertheless, its contents may still be very relevant and of inestimable value to those responsible for the maintenance and operation of precious and irreplaceable signalling equipment on preserved steam and diesel railways, wheresoever those lines might be. Again, the ever growing band of collectors and restorers of old signalling equipment will find the technical material in these pages of more than passing interest. Likewise, enthusiasts viewing the artefacts on display in railway museums might find that this volume can usefully supplement the information provided in simplified guide books and explanatory leaflets. Railway Signal Engineering (Mechanical) is long out of print. The present derivative work is based on the 1932 edition and non of Lewis's original text, nor that later added by Fraser, has been omitted from this reprint. It is in every word as the original, except for a few minor corrections and one important detail. That is, the captions to some of the drawings have been amended to more accurately reflect the intent of the illustration, than did Lewis's original captions. Also note that no illustrations have been omitted, although a few have been added. However, as the most cursory glance through the book pages will show, all the illustrations have been redrawn, in many cases substituting more realistic depictions of signals and mechanisms for the sometimes rather crude sketches in the original. Most notably, colour has been used, not only to provide a more visually appealing book for the enthusiast and the historian, but also in the hope that it adds somewhat to the understanding of technical descriptions and of the illustrations themselves.

This book presents a thorough survey of electric railway development from the earliest days of the London Underground to modern electrified main line trains. Coverage includes chapters on signaling and communications, power supplies, and a detailed survey about traction systems, both AC and DC. The introduction, first of mercury arc rectifiers, and later of power semiconductor controls, is also discussed in detail. The author has a long standing interest in engineering history and has written many papers on aspects of railway technology. This book will be of particular interest to scientists and historians interested in the development of electric railways.

This richly illustrated history chronicles one of the most revolutionary developments in freight railroading during the twentieth century: intermodal shipping, or the use of containers to move cargo between trains, trucks, and oceangoing vessels. It was a development that transformed the movement of freight around the world, with an almost incalculable impact on American industry. Intermodal railroading in North America begins tentatively, with attempts at piggybacking in the 1930s, before moving on to more serious developments in the period from World War II through the 1960s, notably by Canadian Pacific and the New Haven and Southern Pacific railroads. After looking at early intermodal technology and traffic, particularly the formation of pioneering equipment manufacturer and provider TTX, author Brian Solomon turns to the contemporary period. His account of mighty changes in North American shipping ranges from the implications of deregulation and various railroad mergers, to the emergence of partnerships between railroads and trucking and shipping firms. In addition to railroads like Conrail, BNSF, and CSX, this comprehensive history features trucking, freight delivery, and forwarding firms such as J. B. Hunt, Sea-Land, Maersk, and K-Line. It also considers the importance of specialized modern rolling stock, motive power, loading equipment, and intermodal hubs including South Kearney, Seattle, Long Beach, Oakland, and Houston.
