Growing understanding of the interactions between vehicles and track continues to provide benefits in both performance and safety. The Association of American Railroads is developing a vehicle capable of performing a variety of comprehensive vehicle track interaction tests. This paper describes the application objectives and the design and development process followed in the creation of the Track Loading Vehicle (TLV). The TLV is designed to simulate controlled derailment scenarios and provide controlled load environments to quantitfy the dynamic response characteristics of track. The vehicle will apply loads to the track and measure the track response while either stationary or moving. The design of the TLV is based on an extensive list of functional requirements selected to enhance and further the understanding of the processes that take place at the wheel/rail interface. The vehicle is designed to perform extensive measurement and data collection tasks over a diverse range of applications. Typical applications include tests of vertical and lateral track strength, track panel shift, gage widening, flange climb derailments, wheel/rail force/creepage relationships, wheel/rail wear, rail corrugations, and calibration of instrumented wheels and strain-gaged rails.
