METHODS OF HEAT TREATMENT INCLUDING FLAME HARDENING OF BOLTED RAIL FROGS AND SPLIT SWITCHES TOGETHER WITH METHODS OF REPAIR BY WELDING

Study is made of methods of heat treatment and welding repair of bolted rail frogs and split switches. The flame hardening method is included. Service tests of simulated crossing units in the Milwaukee Railroad at Mannheim, Illinois, are reported, and unit maintenance, welding, rail wear, batter, and Brinell hardness are considered. Pending future appraisal, it is concluded that good results are obtained from a majority of welds.
