From both ecological and economical perspectives, electric traction is the most favorable type of power supply for railways. Its reliability depends to a large degree on the contact lines, which have to operate safely under all relevant climatic conditions, needing as little maintenance as possible. Particularly extreme demands are made if overhead contact lines are expected to ensure safe power transmission to electric traction vehicles travelling at speeds over 300 km/h. The authors have used their world-wide experience to provide a clear and comprehensive description of the configuration, mechanical and electrical design, installation and operation of contact lines for electric railways on local and long-distance transportation systems. The book provides students and those embarking on a career in this field with a detailed description of the subject, including the electromechanical and structural requirements. Railway company professionals and manufacturers of contact line systems will find practical guidance in the planning and implementation of systems, as well as appropriate specifications and the technical data they will need, including standards and regulations. Since large sections of the book are dedicated to the system aspects, consultant engineers can also use it as a basis for designing systems and interfaces to other subsystems of electric railway engineering.

Electric traction is the most favourable type of power supply for electric railways from both ecological and economic perspectives. Its reliability largely depends on contact lines, which must operate reliably in all climatic conditions with as little maintenance as possible. Extreme demands arise when overhead contact lines are required to provide reliable and safe power transmission to electric traction vehicles travelling at speeds in excess of 300 km/h. The authors have used their world-wide experience to provide comprehensive descriptions of configuration, mechanical and electrical design, installation and operation of contact lines for electric railways on local and long-distance transportation systems, including high-speed lines. The book provides students and those embarking on a career in this field with a detailed presentation of the subject, including the electromechanical and structural requirements. Railway company professionals and manufacturers of contact line systems will find practical guidance in the planning and implementation of systems, as well as appropriate specifications and the technical data they will need, including standards and other regulations.

Pantograph and Contact Line System comprehensively introduces pantographs, contact lines and their interactions in many areas including geometrics, dynamics, materials, and electrics—helpful to understanding the basic theories of interaction between pantographs and contact lines. The book examines application techniques for system design, construction and maintenance, and includes suggestions to keep pantograph and contact lines working in a safe and stable manner over the long term. In railway traction power supply system, the match between pantograph and contact lines is critical for reliable power transfer. The book provides application techniques for system management and parameter selection in design, construction and maintenance. This book is useful for people who are in catenary and pantograph-related areas such as college teachers and students, researchers and other professional and technical personnel in design, manufacture, construction, operation and maintenance. Includes comprehensive coverage of all types of electric-powered trains Presents pantographs and contact lines as a whole system Explores electrical acting between pantograph and contact line systems for the first time Summarizes techniques in geometrics, dynamics, materials and electrics Establishes theories specific to pantograph and contact line systems Applies theories of pantograph, contact lines and other interactions into system management and parameter selection in design, construction and maintenance Provides the techniques applied in measurement and maintenance

Allows the reader to deepen their understanding of various technologies for both fixed power supply installations of railway systems and for railway rolling stock This book explores the electric railway systems that play a crucial role in the mitigation of congestion and pollution caused by road traffic. It is divided into two parts: the first covering fixed power supply systems, and the second concerning the systems for railway rolling stock. In particular, after a historical introduction to the framework of technological solutions in current use, the authors investigate electrification systems for the power supply of rail vehicles, trams, and subways. Electrical Railway Transportation Systems explores the direct current systems used throughout the world for urban and suburban transport, which are also used in various countries for regional transport. It provides a study of alternating current systems, whether for power supply frequency or for special railway frequency, that are used around the world for the electrification of railway lines, long-distance lines, and high-speed lines. In addition, this resource: Analyzes multiple railway systems from a theoretical and realizable vantage point, with particular regard to functionality, electromagnetic compatibility, and interferences with other electrical systems Studies electric traction railway vehicles, presenting various types of drives and auxiliary devices currently in circulation Discusses solutions employed to ensure interoperability of vehicles that run along lines powered by different systems (e.g., DC and AC, at different frequencies) Electrical Railway Transportation Systems is an ideal text for graduate students studying the subject as well as for industry professionals working in the field.

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.
