RAIL grinding tests on a suburban line and a tortuous main line used mainly by iron ore trains suggests that grinding offers the promise of reducing rail/wheel contact forces and therefore reducing the chances of rail failure; and of prolonging rail life.
The interplay of vertical, lateral, braking, and tractive forces can ressult in a whole range of surface and subsurface rail defects that may result in anything between premature renewal and catastrophic failure. Rail is the ...
