Center Truck Performance on Low-Floor Light Rail Vehicles

This report should be of interest to engineers, manufacturers, maintainers, and others interested in low-floor light rail vehicle (LFLRV) center truck performance issues and their potential solutions for center trucks with unpowered, independently rotating wheels (IRWs). The report describes performance issues observed in the operation of LFLRV center trucks (focusing on 70% low-floor vehicles), such as excessive wheel wear and noise and occasional derailments, and provides guidance on how to minimize or avoid these issues. The report also includes guidance on LFLRV specifications, maintenance, and design, as well as on related infrastructure design and maintenance, to maximize performance of these LFLRV center trucks.
