Circuits For Colour Light Signalling

Despite modern appearances, colour light signalling has been around since the 1920s and is just as full of subtle details and variations as 'traditional' semaphore signalling. The inclusion of a working signalling system within a model railway layout is technically challenging but adds realism and 'wow' factor. This new book contains a brief history of the development and deployment of colour light signalling in the UK; a basic explanation of how track design influences signalling design; an overview of the different types of point motor and, finally, descriptions of the different components that make up a signalling system and how these components are used and controlled. It is an extensive guide to developing and adding realistic colour light signalling to a model railway layout.

For over 150 years Britain's railways have relied on a system of semaphore signalling, but by 2020, all semaphore signals and lineside signal boxes will be gone. A Contemporary Perspective on GWR Signalling provides a unique record of the last operational mechanical signalling and infrastructure on Britain's railway network, as it applied to the former Great Western Railway (and lines owned jointly with other companies). It also includes a comprehensive explanation of what mechanical signalling is and how it works. Beautifully illustrated with over 400 contemporary images and with detailed information from a 2003-2014 survery, this is an essential resource for anyone with an interest in the traditional signalling systems of railways in Britain. The book covers: lineside signalling equipment - semaphore signals, brackets and gantries, and other variations; ways of working, from Absolute Block to Track Circuit Block (TCB); detailed coverage of the signal boxes and infrastructure on Network Rail, including routes through Shrewsbury, Hereford, Worcester, Cornwall, Chester and North Warwickshire; and diagrams of the major routes.

For over 150 years Britain's railways have relied on a system of semaphore signalling, but by 2020, all semaphore signals and lineside signal boxes will be gone. In his previous book, author Allen Jackson covered the GWR lines; here, he continues his journey by providing a pictorial record of the last operational signalling and infrastructure on Britain's railway network, as it applied to the former London, Midland and Scottish Railway (and lines owned jointly with other companies). This second volume covers the routes of the London and North Western Railway, the Caledonian Railway and the Highland Railway. Beautifully illustrated with over 400 contemporary colour photographs and with detailed information from a 2003-2014 survey, this is an essential resource for railway enthusiasts, rail historians, railway modellers and anyone interested in this aspect of Britain's heritage.

Electrical Engineer's Reference Book, Fourteenth Edition focuses on electrical engineering. The book first discusses units, mathematics, and physical quantities, including the international unit system, physical properties, and electricity. The text also looks at network and control systems analysis. The book examines materials used in electrical engineering. Topics include conducting materials, superconductors, silicon, insulating materials, electrical steels, and soft irons and relay steels. The text underscores electrical metrology and instrumentation, steam-generating plants, turbines and diesel plants, and nuclear reactor plants. The book also discusses alternative energy sources. Concerns include wind, geothermal, wave, ocean thermal, solar, and tidal energy. The text then looks at alternating-current generators. Stator windings, insulation, output equation, armature reaction, and reactants and time-constraints are described. The book also examines overhead lines, cables, power transformers, switchgears and protection, supply and control of reactive power, and power systems operation and control. The text is a vital source of reference for readers interested in electrical engineering.

Automation and Control in Transport reviews the significant advances in transport automation and control. All the present and future foreseeable modes of transport, particularly railways, are treated mathematically. Topics range from dynamic systems to route capacity, vehicle spacing, traffic congestion and regulation, and traffic surveillance and control. Vehicle detection and identification, sorting and marshalling, control of acceleration and power, steering, and control of braking are also given consideration. This volume consists of 16 chapters and begins with a discussion of the dynamic behavior of a system (that is, how it responds to changing situations) from the point of view of control engineering. Open-loop systems, closed-loop systems, and the use of a phase-plane diagram to represent the response of a control system are described. The chapters that follow focus on the capacity of a transport system based on the laws for vehicle following, signaling as a means of controlling vehicle spacing in railways, and traffic regulation to address problems of congestion. The reader is also introduced to the use of computers to aid in traffic surveillance and control, means for detecting and identifying the presence of a vehicle, and communication of control signals to moving vehicles. The book concludes by assessing future prospects for transport automation and control. This book will be of interest to traffic engineers as well as students and practitioners of mechanical engineering.
