"TRB's Transit Cooperative Research Program (TCRP) Report 114: Center Truck Performance on Low-Floor Light Rail Vehicles examines performance issues observed in the operation of low-floor light rail vehicle (LFLRV) center trucks (focusing on 70-percent low-floor vehicles), such as excessive wheel wear and noise and occasional derailments, and provides proposed guidance on how to minimize or avoid these issues. The report also includes suggestions on LFLRV specifications, maintenance, and design, as well as on related infrastructure design and maintenance, to maximize performance of these LFLRV center trucks"--Publisher's description.

The report investigates the state of the art of low-floor light rail vehicles and assesses the applicability of their use in North America. Low-floor light rail vehicle categories have been developed to facilitate the understanding of the different types of vehicles and their applications. The report describes the growing trend toward low-floor light rail vehicles and the reasons for this growth. It provides an extensive compilation of data on low-floor light rail vehicles, information on North American light rail system characteristics, and an analytical perspective on key issues relevant to the applicability of this technology in North America. The report also develops example applications to demonstrate the cost-effectiveness of using low-floor light rail vehicles, the source of risk, and the trade-offs regarding the use of low-floor versus high-floor light rail vehicles.

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 book offers a snapshot of the latest research and developments in road and railway vehicle dynamics. Gathering peer-reviewed contributions to the 27th Symposium of the International Association of Vehicle System Dynamics (IAVSD), held online on August 17–19, 2021, from Saint Petersburg, Russia, it offers extensive information for both researchers and professionals in the field of ground vehicle dynamics, control and design. It covers cutting-edge methods and solutions for solving ground vehicle system dynamics-related problems, concerning control and monitoring, performance, safety and braking of road and rail vehicles, including electric and autonomous ones. Further, it reports on significant advances in vehicle design, and important applications to improve ride comfort. Overall, the book provides academics and professional with a timely reference guide on theories and methods to understand, analyze and improve vehicle stability and dynamics in a broad range of different operating conditions.
