Contact Lines for Electric Railways


Book Description

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.




Contact Lines for Electrical Railways


Book Description

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.

Electrical Railway Transportation Systems


Book Description

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.

Portland's Interurban Railway


Book Description

At the end of the 19th century, Portland led the nation in the development of interurban electric railways. The city became the hub of an electric rail network that spread throughout the Willamette Valley. This is the story of the pioneering local railways that started it all as they built south along the Willamette River to Oregon City and east to Estacada and Bull Run in the foothills of the Cascade Mountains. More than 200 historic images illustrate Portland's Interurban Railway from its rudimentary beginnings through the peak years, when passengers rode aboard the finest examples of the car builders' art, to the sudden end in 1958.

Pacific Electric Railway


Book Description

The Pacific Electric Railway originally provided reliable transportation across more than 1,000 miles of track. Postwar society's affair with the automobile led to the loss of an infrastructure that could have formed the basis for an enviable modern light-rail system, one that current society would be happy to utilize. Authors Steve Crise and Michael Patris look back at the railway and its landscape today. Both serve on the board of the Pacific Electric Railway Historical Society, from whose archives most of these images are taken.




The Electric Interurban Railways in America


Book Description

One of the most colorful yet neglected eras in American transportation history is re-created in this definitive history of the electric interurbans. Built with the idea of attracting short-distance passenger traffic and light freight, the interurbans were largely constructed in the early 1900s. The rise of the automobile and motor transport caused the industry to decline after World War I, and the depression virtually annihilated the industry by the middle 1930s. Part I describes interurban construction, technology, passenger and freight traffic, financial history, and final decline and abandonment. Part II presents individual histories (with route maps) of the more than 300 companies of the interurban industry. Reviews "A first-rate work of such detail and discernment that it might well serve as a model for all corporate biographies. . . . A wonderfully capable job of distillation." —Trains "Few economic, social, and business historians can afford to miss this definitive study." —Mississippi Valley Historical Review "All seekers after nostalgia will be interested in this encyclopedic volume on the days when the clang, clang of the trolley was the most exciting travel sound the suburbs knew." —Harper's Magazine "A fascinating and instructive chapter in the history of American transportation." —Journal of Economic History "The hint that behind the grand facade of scholarship lies an expanse of boyish enthusiasm is strengthened by a lovingly amassed and beautifully reproduced collection of 37 photographs." —The Nation
