METALLURGICAL EFFECT OF RAIL-CROPPING METHODS

Metallurgical effects of rail-cropping methods are compiled and presented. New 136-lb and second-hand 131-lb rail ends cut by a friction saw are investigated to determine possibilities of using the saw in the cutting of closure rails for packaged turnouts and rails to be used in the manufacture of switch points, frogs, and other products. Depth of the heat-affected zone is decreased with the thickness of cross section; there is no significant difference between the new and second-hand rail. It is determined that the heat-affected zone caused by this method is not as great as the zone caused by some of the earlier abrasive cutting methods and may not have a harmful effect even though the presence of martensitic structures is never desirable.
