Testing of latest top-of-rail friction modification materials at FAST

摘要

Transportation Technology Center, Inc. (TTCI), evaluated top-of-rail (TOR) friction modification (FM) materials from two suppliers at the Facility for Accelerated Service Testing (FAST), Pueblo, Colo., to determine optimum application rate. One water-based product tested had the highest percent reduction in lateral curving forces, 67 percent for the low rail and 55 percent for the high rail, with an application rate of 12.26 in~3/1,000 axles. The highest percent reduction of an oil-based product was 54 percent for the low rail and 43 percent for the high rail, with an application rate of 5.49 in~3/1,000 axles.
