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 an ecological and an economic perspective. In the case of urban mass transit and high-speed trains it is the only possible type of traction. Its reliability largely depends on contact lines, which must operate in all climatic conditions with as high availability and as little maintenance as possible. Extreme demands arise when overhead contact lines are required to provide reliable and safe power transmission to traction vehicles travelling at speeds in excess of 250 km/h. The authors have used their worldwide experience to provide comprehensive descriptions of configuration, mechanical and electrical design, installation, operation and maintenance of contact lines for local and long-distance transportation systems, including high-speed lines. In this book, railway company professionals and manufacturers of contact line systems, students and those embarking on a career in this field will find practical guidance in the planning and implementation of systems, product descriptions, specifications and technical data, including standards and other regulations. Special emphasis is laid on the interaction of the individual components of power supply, especially between contact lines and pantographs. Since large sections of the book are dedicated to system aspects, consultant engineers can also use it as a basis for designing systems as well as interfaces to other subsystems of electric railway engineering. The contents of the book are rounded off by examples of running systems.

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.

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.

The Railway Research Institute (Instytut Kolejnictwa) in Warsaw was established in 1951 and was, until 2000, part of the Polish State Railways (PKP). At present, it serves as an independent entity, it is subordinated to the minister responsible for transport. Since its inception, the Institute has been the centre of competence for technology, technique and organization of operation and services in rail transport, particularly in respect to innovation. One of its fundamental tasks also includes activities connected with safety which are carried out in close cooperation with the National Safety Authority, i.e. the Office of Rail Transport. At the same time the Institute participated in the process of upgrading and modernization of the rail network in Poland. Experience in high speed rail, gained as a result of international cooperation and basing on the effort to increase speed on railway lines in Poland (so far 200 km/h), is included in the monograph “Koleje Dużych Prędkości w Polsce” (High Speed Rail in Poland) published in 2015 for the benefit of the Polish reader. This monograph aims at reaching an international audience of experts so as to present Polish determinants of HSR implementation. In order to elaborate this monograph, apart from specialists from the Railway Research Institute, experts from other research and academic centres were invited. Not only presenting a wide range of problems connected with future construction of High Speed Lines in Polish conditions, but also a number of operational ones. The authors have created a reference work of universal character, solving problems in order to build and operate high speed rail systems in countries on a similar level of development as Poland. Features: providing requirements for design and upgrade of engineering works on High Speed Rail development information on restructuring and building railway lines for countries starting to develop a High Speed Rail system dealing with organizational, engineering, socioeconomic and economic demands for transport services and the formation of human resources for constructing and operting a High Speed Rails system. Presenting these problems on the international arena will facilitate future cooperation and application of world experience to create HSR in Poland and integrate the Polish HSR network into the international one.

From 1901 to 1938 the Lake Shore Electric claimed to be—and was considered by many—"The Greatest Electric Railway in the United States." It followed the shore of Lake Erie, connecting Cleveland and Toledo with a high-speed, limited-stop service and pioneered a form of intermodal transportation three decades before the rest of the industry. To millions of people the bright orange electric cars were an economical and comfortable means of escaping the urban mills and shops or the humdrum of rural life. In summers during the glory years there were never enough cars to handle the crowds. After reaching its peak in the early 1920s, however, the Lake Shore Electric suffered the fate of most of its sister lines: it was now competing with automobiles, trucks, and buses and could not rival them in convenience. The Lake Shore Electric Railway Story tells the story of this fascinating chapter in interurban transportation, including the missed opportunities that might have saved this railway.
