SWITCHES WITH RAILS END HARDENED AT THE HEELS AND RAIL BOUND MANGANESE FROGS WITH TOE AND HEEL RAIL END HARDENED

The purpose of this test was to determine the practicability and economy of end hardening for heat treating rail ends on frogs and switch points. The test included four frogs and two complete switches with treated rail ends, and two frogs and complete switches without treatment for comparison. There was no apparent advantage to be gained by end hardening or heat treating rail ends. Results of this test indicate that joint batter is not a governing factor in determining need for renewal of frogs and switches. Pending further development the end hardening of frogs and switch rails is not recommended.
