摘要: The railway transport braking processes are likely to form surface defects on the tread if wheel locks up and slides along rail. This action can be produced by a defective, frozen or incorrectly tuned brake, as well low rail-wheel adhesion caused environmental conditions (rain, snow, leaves, etc.). abrasive effect of skidding causes high wear rolling (a wheel-flat), with lengths ranging typically from 20 over 100 mm.
