Influece of Weather Condition upon Adhesion between Rails and Running Wheels on Main Lines: (Results Investigated on JR Nikko Line by the Slipping Adhesion Test Truck)

Abstract

The authors constructed “slipping adhesion test bogie” designed upon a new idea of measuring the coefficient of adhesion continually while running, and have observed the state of adhesion on main lines since 1985. Recently, they placed a car equipped with this bogie on a steep line where wheel-spin and skidding of rolling stock had been friquently the cause of troubles. As the result of runs of the car under various weather conditions such as fine, fog, snow, sleet and frost, influence of the weather condition upon the adhesion between rails and wheels has been made clear and evaluated quantitatively. © 1990, The Japan Society of Mechanical Engineers.
