Methods of Reducing Wear of Rails / Railway Wheels

Followings are some different techniques and methods for reducing wear of rails.Use of special alloy steel, Good maintenance of track, Reduction of expansion gap, Exchange of inner and outer rail on curve, Use of lubricating oil on the gauge face, By coning of wheel, Reduction of the number of joints, interchanging inner and outer rails, Tilting of rails
