Original Abstract

Top-of-rail products are commonly used for friction modification in wheel-rail contact. However, the effect of environmental conditions and contaminants on their performance remains unclear. In this study, three commercial top-of-rail products were contaminated by different amounts of water. The laboratory tribometer in ball on-disc configuration was used to measure the coefficient of adhesion in contaminated contact. The results show that water influenced tested top-of-rail products significantly. A very low coefficient of adhesion occurred in tests with oil-based top-of-rail products suggesting that water could cause traction problems on the actual railway where friction modification is being used. Water-based top-of-rail products showed more resistance to water contamination.
