Rail corrugation is a wear development phenomenon that forms periodic irregularities on the top of the rail as a railway runs over it repeatedly. It causes vibration and noise and ultimately decreases traveling safety and environmental friendliness. Although application of friction modifiers and rail corrections are undertaken as measures against corrugation, these are expensive and require a great deal of effort. Therefore, elucidation of the rail corrugation mechanism is required. In this study, to evaluate the rail corrugation mechanism, an experiment was conducted using a 1/10 scale two-axle bogie model. A test of 15,000 repeated passages was carried out using a track loop that simulated the contact between the wheel and rail in a full-scale railway. To consider the mechanism of corrugation development, six influencing factors were measured: rail surface condition, rail surface shape, rail acceleration, wheel/rail shape, contact position, and contact force.
