The Association of American Railroads (AAR) and the Federal Railroad Administration (FRA) jointly funded a research program to evaluate the safety and performance of operating heavy axle load (HAL) trains for freight service. The program evaluated the effect of 315-kip cars on track, track components and track maintenance. AAR funded companion efforts to evaluate the economics of HAL service and to monitor the effect of and the rate of introduction of 268-kip cars in revenue service. Turnout frogs were tested on the Union Pacific North Platte Subdivision in Nebraska. The article reviews results of these research programs.
