Original abstract
Top-of-rail (TOR) products are designed to optimize adhesion, reduce wear and mitigate noise from the wheel -rail interface. Prior to testing these products in field conditions, a laboratory approach is suitable because it is not time-consuming and expensive. This study aims to design a benchmarking methodology to investigate the per-formance of TOR products using a standard tribometer in a ball-on-disc configuration. The resulting method-ology is based on a multi-parameter approach enabling the assessment of TOR products from multiple perspectives. The core of the methodology is formed by traction tests and a robust evaluation phase resulting in a performance map dividing TOR products into four performance classes, Q1-Q4, based on which a suitable TOR product can be chosen for further testing.
