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.

This guide offers a blueprint for co-designing and refreshing evidence-informed, needs-based solutions. Written for service providers, organizations, and system leaders who support transitions to adult life for young people with disabilities, across healthcare, community, education, and social service sectors. The digestible content and visually appealing graphic design makes the guide easy to read and navigate, allowing you to choose which sections are most relevant to you. Start with an introduction to using evidence and best practices in transition practice. Then read about our transformative approach to solution design, presented in four key tenets (Frameworks, Solution-focused approach, Human centered design, and Collaboration). To see how we put these tenets in action, skip ahead to four examples of transitions solutions implemented at Canada’s largest pediatric rehabilitation hospital (Holland Bloorview Kids Rehabilitation Hospital). To action the tenets in your own practice, use the evidence-informed and practice-based supporting materials in the two appendices. Each section contains valuable resources, tools, and tips for your practice.
Links Geotechnics with Railway Track Engineering and Railway Operation Good railway track and railway operations depend on good geotechnics, in several different ways and at varying levels. Railway Geotechnics covers track, track substructure, load environment, materials, mechanics, design, construction, measurements, and management. Illustrated by
In Designs for the Pluriverse Arturo Escobar presents a new vision of design theory and practice aimed at channeling design's world-making capacity toward ways of being and doing that are deeply attuned to justice and the Earth. Noting that most design—from consumer goods and digital technologies to built environments—currently serves capitalist ends, Escobar argues for the development of an “autonomous design” that eschews commercial and modernizing aims in favor of more collaborative and placed-based approaches. Such design attends to questions of environment, experience, and politics while focusing on the production of human experience based on the radical interdependence of all beings. Mapping autonomous design’s principles to the history of decolonial efforts of indigenous and Afro-descended people in Latin America, Escobar shows how refiguring current design practices could lead to the creation of more just and sustainable social orders.
High-speed turnouts, a key technology for high-speed railways, have a great influence on the safe and stable running of high-speed trains. Design of High-Speed Railway Turnouts: Theory and Applications, comprehensively introduces the technical characteristics and requirements of high-speed turnouts, including design theories and methods of turnout layout geometry, wheel and rail relations, track stiffness, welded turnout, turnout conversion, turnout components, and manufacture and laying technologies of turnouts. Analyzing the operational problems of China's high-speed turnout in particular, this book discusses the control of structure irregularity, state irregularity, geometrical irregularity and dynamic irregularity during the design, manufacture, laying, and maintenance of turnouts. At the end of this reference book, the author provides high-speed turnouts management methods, maintenance standards, testing and monitoring technology, and maintenance technology. Design of High-Speed Railway Turnouts: Theory and Applications will enable railway technicians all over the world to develop an in-depth knowledge of the design, manufacture, laying, and maintenance technology of high-speed turnouts. - The first book in the world to focus explicitly on high-speed turnouts, including design, construction, maintenance and management of high speed turnouts - Expounds the theory of vehicle-turnout system coupling dynamics in detail, aligning this with several examples of computation, and examines the results of dynamic experiments which validate the theory - Written by Ping Wang, who is recognized as a leading researcher and main developer of high-speed turnouts in China
