Side abrasion is mainly

Rail abrasion is the friction between the wheel and the rail to produce wear and tear on the head of the rail. Rail abrasion in a straight line and curve appear different forms. Straight mainly for vertical wear and joint part of the saddle wear. On the curve, it is mainly the lateral abrasion of the outer stock rail, and the crushing and wave abrasion of the inner stock rail. Lateral wear is particularly serious on small radius curves, and is often scrapped due to overrunning of the wear limit. The main measures to slow down the curve rail side abrasion is to lay high strength alloy steel rail or full-length quenched rail, the use of abrasive tread wheels and reasonable track structure parameters. As auxiliary measures, ground rail oiler and locomotive wheel edge oiler can be used to reduce the friction coefficient between wheels and rails. Waveform abrasion is a regular undulating uneven uneven abrasion phenomenon on the top surface of the rail, the cause is complex. At present, the only way is to have a waveform abrasion of the rail with grinding train grinding to make it completely eliminated.
