MEASUREMENT OF RAIL SURFACE CONDITIONS (REPORT 2)--FRICTION OF RAIL SURFACE

Measuring methods of rail surface conditions and of friction of rail surface in the field developed, and applied to measurements in a performance test of ED75S AC locomotive. The friction varied during the measurement and was affected by the weight of the slider. The friction of the rail on the definite position varied with time, and values ranging 0.29 to approximately 0.53 were obtained. Friction variation in the direction of the rail was small. Effect of wetting on the friction was also small, whereas oiling of the rail produced extraordinarily reduced friction, which recovered the original values by the passage of several trains.
