Slight rail gnawing wheel rim and the side of the orbit has obvious traces of wear; Severe gnawing causes flange and track side metal to flake or deform outwards.

  1. Reduce the service life of wheels
  2. Wear track

The wheels rail gnawing increases the wear of the track, Severe cases will orbit grinding out the steps, until the change of orbit.

  1. Increase the running load
