This report includes the results of a research task carried out under TCRP Project D-7, "Joint Rail Transit-Related Research with the Association of American Railroads/Transportation Technology Center, Inc." The report includes comparisons of two guard rail installation philosophies and the effects of vehicle types, wheel flange angle, wheel/rail (W/R) friction coefficient, curve radius, cant deficiency, and track perturbation on flange climb derailments that have been investigated through simulations. It offers guidance that transit agencies can follow in their W/R maintenance practices for both transit rail cars and light rail vehicles. This report should be of interest to engineers involved in the design, construction, maintenance, and operation of rail transit systems.
