Available in PDF, EPUB and Kindle. Book excerpt: TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.
Download or read book The Railway written by Andrew Dow and published by Wharncliffe. This book was released on 2014-10-30 with total page 1156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Never before has a comprehensive history been written of the track used by railways of all gauges, tramways, and cliff railways, in Great Britain. And yet it was the development of track, every bit as much as the development of the locomotive, that has allowed our railways to provide an extraordinarily wide range of services. Without the track of today, with its laser-guided maintenance machines, the TGV and the Eurostar could not cruise smoothly at 272 feet per second, nor could 2,000-ton freight trains carry a wide range of materials, or suburban railways, over and under the ground, serve our great cities in a way that roads never could. Andrew Dow's account of the development of track, involving deep research in the papers of professional institutions as well as rare books, company records and personal accounts, paints a vivid picture of development from primitive beginnings to modernity. The book contains nearly 200 specially-commissioned drawings as well as many photographs of track in its very many forms since the appearance of the steam locomotive in 1804. Included are chapters on electrified railways, and on the development of mechanised maintenance, which revolutionised the world of the platelayer.

Available in PDF, EPUB and Kindle. Book excerpt: Explains and resolves the electromagnetic compatibility challenges faced by engineers in transportation and communications This book is a mathematically-rich extension of courses required to maintain the Federal Communications Commission (FCC), the Canadian Standards Association (CSA), and the European Union certifications. The text provides an in-depth study of the electromagnetic compatibility (EMC) issues related to specific topics in transportation and communications, including Light Rail Transit, shadow effects, and radio dead spots, through the analysis of real-world case studies in the United States and Europe. The author provides Cartesian, cylindrical, and spherical solutions that can be applied to Maxwell's and Wave Equations. The book covers topics such as SCADA Systems, shielding, and complexities of radio frequencies and their effect on communication houses. The author also provides information for alternative industries to apply the solutions from the case studies and background content to their own professions. Presents a series of over twenty real-world case studies related to EMC in transportation and communications Covers power line radiation, shadow effects on subway cars, train control systems, and edge distortions Includes the OATS testing method and Department of Transportation (DOT) test Provides access to a companion website housing power point slides and additional appendices Electromagnetic Compatibility: Analysis and Case Studies in Transportation is a reference for practicing engineers involved in transportation and communications, as well as post-graduate engineering students studying transportation and communications in engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Philadelphia exploded in violence in 1910. The general strike that year was a notable point, but not a unique one, in a generations-long history of conflict between the workers and management at one of the nation's largest privately owned transit systems. In Running the Rails, James Wolfinger uses the history of Philadelphia’s sprawling public transportation system to explore how labor relations shifted from the 1880s to the 1960s. As transit workers adapted to fast-paced technological innovation to keep the city’s people and commerce on the move, management sought to limit its employees’ rights. Raw violence, welfare capitalism, race-baiting, and smear campaigns against unions were among the strategies managers used to control the company’s labor force and enhance corporate profits, often at the expense of the workers’ and the city’s well-being. Public service workers and their unions come under frequent attack for being a "special interest" or a hindrance to the smooth functioning of society. This book offers readers a different, historically grounded way of thinking about the people who keep their cities running. Working in public transit is a difficult job now, as it was a century ago. The benefits and decent wages Philadelphia public transit workers secured—advances that were hard-won and well deserved—came as a result of fighting for decades against their exploitation. Given capital’s great power in American society and management's enduring quest to control its workforce, it is remarkable to see how much Philadelphia’s transit workers achieved.
