Railway Track And Track Work

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.

A proper quality of a track and other infrastructure objects represents a basic requirement for train safety and punctuality. Most of the physical systems and their components deteriorate over time. This affects performance and may lead to failures. Albert Einstein said, “You have to learn the rules of the game. And then you have to play better than anyone else.” Only if we understand how the whole system works, taking into account its imperfections and how they influence its quality and performance will we be able to learn the rules of the game and “play better.” The book provides the readers with the necessary functional knowledge of track behaviour and comprehensively covers the function of the various track components, their interaction as elements of the track system, as well as the interaction of the track with railway vehicles. By presenting important tools for a deep understanding of track-behaviour this book aims to be a reference guide for infrastructure managers and to help them to find ways improving track quality for optimum long-term behaviour.

Railway Track Engineering presents conventional methods of track construction, maintenance and monitoring, along with modern sophisticated track machines. It also comprehensively covers design details and specifications of important track componentsChanges in the revised edition include:Explanation of the hitherto little understood phenomenon of rolling contact fatigue in rails and practical steps to deal with it. New technology of alumino-thermic rail welding. New guidelines for ultrasonic rail flaw detection. Ballastless track for metros, mainlines and washable aprons. Track standards for ultra high-speed lines in India. Track structure for Dedicated Freight Corridors. Technology of fully mechanized track construction with the deployment of simple track laying equipment to highly sophisticated track-laying trains.Richly illustrated with photographs and line drawings, this book will be useful to professionals and students.
