Powered by twin 1,650bhp engines, the Deltic was Britain's first truly reliable diesel main line locomotive.

Andrew Fowler is a well known writer of railway history, with a regular feature in Railway Herald Magazine. The Deltic class 55 Locomotives were some of the most successful, first generation diesels introduced to British Railways, being constructed from 1960-1962 and numbering twenty two, in the production class. The prototype machine was constructed in 1956 and was tested extensively on express trains on the London Midland and Eastern Regions of B R, until 1960. The interest and enthusiasm, for the class is reflected in the fact, that six examples of the class are preserved, including the 1956 prototype. The Baby Deltics, were a derivative Locomotive design, using one rather then two engines, for use on outer suburban and short main line semi fast services. Only ten Baby Deltics were constructed between 1961-1962, for use on services out of London Kings Cross. The Baby Deltics were all withdrawn within a decade, as they were not very successful in main line service.

A wonderful collection of photographs showing the last years of the Deltics, their retirement from service and preservation.

The Royal Navy invented the fast motor torpedo boat during the First World War, and used it and other small coastal craft to great effect during the Second. This book tells the dramatic story of British coastal forces, both offensive and defensive, in both World Wars and beyond. In the Second World War, British coastal forces fought a desperate battle to control the narrow seas, particularly the Channel and the North Sea, and took the war to the coasts of German-occupied Europe, fighting where larger warships could not be risked. They also made a significant contribution to victory in the Mediterranean, but it was primarily warfare in home waters that shaped wartime British Coastal Forces and left lessons for postwar development. In this book, Norman Friedman uniquely connects the technical story of the coastal craft and their weapons and other innovations with the way they fought. In both world wars much of the technology was at the edge of what was feasible at the time. Boats incorporated considerable British innovation and also benefited from important US contributions, particularly in supplying high-powered engines during World War II. In contrast with larger warships, British coastal forces craft were essentially shaped by a few builders, and their part in the story is given full credit. They also built a large number of broadly similar craft for air-sea rescue, and for completeness these are described in an appendix. This fascinating, dramatic story is also relevant to modern naval thinkers concerned with gaining or denying access to hostile shores. The technology has changed but the underlying realities have not. This book includes an extensive account of how coastal forces supported the biggest European example of seizing a defended shore, the Normandy invasion. That was by far the largest single British coastal forces operation, demanding a wide range of innovations to make it possible. Like other books in this series, this one is based very heavily on contemporary official material, much of which has not been used previously – like the extensive reports of US naval observers, who were allowed wide access to the Royal Navy as early as 1940. Combined with published memoirs, these sources offer a much more complete picture than has previously appeared of how Coastal Forces fought and of the way in which various pressures, both operational and industrial, shaped them.

A pocket guide to 60 of the most iconic British locomotives of the last two centuries, which will have wide appeal as a handy yet detailed reference book on British locomotives. Since the 1800s locomotives have steamed, chugged and sparked their way into the nation's affections. These powerful engines were the drivers of the Industrial Revolution, and to the present day carry passengers and freight to every corner of Britain. But do you know your Locomotion from your Rocket, or your Gresley Class A4 from your Princess Coronation Class? How heavy is the Flying Scotsman? And who designed the Britannia Class? The Loco Spotter's Guide answers all of these questions, with first-class illustrations portraying more than 60 of the most important steam, diesel and electric designs, including all-important specifications and technical details to aid any would-be loco spotter.

Advances in Hydroscience, Volume 1 considers the physical theories and mathematical analyses of a broad spectrum of specialized subjects in various branches of hydroscience, including hydrodynamics, hydrology, hydrochemistry, hydrophysics, hydrobiology, hydrometeorology, oceanology, hydrogeology, naval science, and water resources. This book contains five chapters, and begins with a presentation of scientific and engineering advances in the field of sonar and hydroelasticity. The following chapter deals with the fundamental principles and concepts of statistical hydrodynamics in porous media and their significance in various engineering applications. These topics are followed by a discussion on the concepts of theoretical incompressible fluid dynamics, with a special emphasis on the field of hydroballistics. The last chapter provides first a brief introduction to the basic principles and fundamental equations of well hydraulics, followed by a survey of its importance to water economy in arid and semiarid regions of the world. This book will be of great value to research workers and practitioners in the interdisciplinary field of hydroscience.
