ABSTRACT: This report describes the service evaluation of frogs, switches, and guard rails on the Facility ofr Accelerated Service Testing track near Pueblo, Colorado. The selected components were measured and inspected at scheduled intervals determined by service loading. Wear and maintenance data per MGT are given for each metallurgy and loaction, and the conditions influencing performance are here thoroughly discussed. The authors note that engineering personnel from participating (donor) railroads and suppliers were frequently on hand to observe the frog turnout performance tests and that changes in design and maintenance practices have resulted.
