Rail surface performance as influenced by wayside-based top-of-rail friction control: watching wayside-based TOR friction control as it pertains to rail wear and curving performance.(TTCI R&D)

For the past five year, the Association of American Railoads,the transportation Technology Center, Inc.,the supply industry and various member railroads have been monitoring the performance of wayside-based top-of-rail (TOR) friction control at a number of field locations.

Emphasis has been placed on monitoring rail wear and curving performance. Together with improving rail wear life around 40 percent, controlling TOR friction has shown a reduction in curving force in the range of 30 percent to 40 percent, which can result in reduced rail/wheel wear, lower tie/fastener damage ...
