Field demonstrations of two prototype high-speed tribometers

Abstract

Transportation Technology Center, Inc. (TTCI), a subsidiary of the Association of American Railroads (AAR), operated two high-speed tribometer (HST) prototypes on five revenue railroad sites to evaluate their ability to collect friction data in the field. TTCI initially tested these prototypes for basic operating, safety and data collection performance under closed loop conditions at the Federal Railroad Administration's Transportation Technology Center (TTC), Pueblo, Colorado, USA.
