This study focused on attempts to use traction oil as a wheel/rail lubricant. Traction oil is a recently developed lubricant material, and is thought to provide a higher traction coefficient than conventional lubricating oil. In laboratory tests, a traction coefficient of 0.14 was obtained for traction oil, and the relationship between traction coefficients and slip rates was found to depend mainly on the oil type. It was also clarified that the anti-wear properties of traction oil could be controlled using a certain quantity of anti-wear additive. It has been proved that traction oil is promising as a wheel/rail lubricant, but further efforts are required to clarify the related effects on other significant factors such as lateral force.
