Abstract:

This research serves to evaluate the ability of optical detection techniques for ascertaining the lubricity of revenue service track from a moving platform. A literature review is presented that covers the rail vehicle dynamics that drive the need of Top-of-Rail lubrication and directly affect the manner in which the Top-of-Rail Friction Modifiers (TORFM) and flange grease both spread down rail and eventually wear away. This literature review also highlights previous research in the field of rail lubrication and the benefits that rail lubricants, specifically TORFM, provide for the railroads. Finally, the literature review covers the governing optical principals inherent to the synchronous spot radiometer that has been developed for use in the research and also addresses the drawbacks and challenges inherent to applying this type of instrument to the railroad industry.
