WebTrain dynamic forces that include the effects of friction and impact between the wheel flanges against the gauge side of the rail and those due to sway, concussion, buff and slack-action. The rail-flange forces vary with speed and quality of the wheel tread and rail, as well as the tracking effect of the trucks. WebJun 17, 2005 · Keywords: railway, rail, rail wear, gauge width, curve, rail wearing intensity, wheel flange. 1. Introduction Rail is the main bearing element of the upper track construction. Loads, caused by the rolling-stock wheels, act on the element. Therefore, rails have to withstand large dynamic loads in vertical, longitudinal and lateral directions.
