The Application of Laser Technology for Railroad Top of Rail (TOR) Friction Modifier Detection and Measurements
… of determining rail lubricity of top-of-rail friction modifier is investigated in this research. A literature review of optical sensors as they relate to detecting thin layers is presented, as well as a literature review of the significant aspect of surface roughness on optical signature. Both …

Experimental Evaluation of Wheel-Rail Interaction
… surface is analyzed and related to wheel-rail friction. It is determined that the accumulation of the worn material at the contact surface, which appears as a fine gray powder, acts as a friction modifier that increases friction. The friction (traction) increase occurs asymptotically. …

The feasibility of using electrostatic charge condition monitoring for lubricant additive screening
… charge measurements and cross-correlated with friction, wear and off-line surface chemistry analysis. The first study involved electrostatic monitoring of valve-train contacts, which was a continuation of previous electrostatic monitoring work carried out to relate wear and electrostatic …

Application of Optical Detection Methods for Top-of-Rail (TOR) Lubricity Evaluation on a Moving Platform for Revenue Service Track
… affect the manner in which the Top-of-Rail Friction Modifiers (TORFM) and flange grease both spread down rail and eventually wear away. This literature review also highlights previous research in the field of rail lubrication and the benefits that rail lubricants, specifically TORFM, provide …
