Flash-butt welded, 91-lb. rail is being flame-hardened to increase the Brinell hardness of the rail end 50 to 100 points above the remainder of the rail. The hardening extends 1.5 to 2 in. from the rail-ends, to a depth of 0.189 to 0.25 in. Experiments have been carried out at temperatures from 32 to 90F, with practically no variation in results. The hardening process is described in detail.
