Appl. No.:

17/949129

International Classification:

E01B 19/00
H05B 6/10

Abstract:

A magnetic induction heating system for a railroad switch crib is a system that prevents the accumulation of ice or snow on or around the railroad switch crib area which can cause malfunction of the railroad switch components. To do so, the system includes at least one coil assembly that can be mounted under the railroad crib space between adjacent ties. The at least one coil assembly is designed to generate an oscillating electromagnetic field that agitates the atoms of the different metal components of the railroad crib space so that the metal components radiate enough heat that melts any accumulated ice or snow around the components. The at least one coil assembly can also be used to heat the railroad switch drive motor assembly by placing the at least one coil assembly under the motor drive unit to keep the unit free of ice or snow accumulation.

Abstract:

A magnetic railroad clip is able to stay engaged to the rails of a railroad track as a train passes over the rails. The magnetic railroad clip includes a base plate, a first brace, a second brace, and at least one magnet. The base plate is used to brace the underside of a rail of a railroad track. The first brace and the second brace allow the magnetic railroad clip to be pressed against the sides of the rail. The second brace further allows a heating device such as, but not limited to, a hot switch induction head to be mounted to the rail. The at least one magnet provides a magnetic fulcrum effect that prevents the first brace from dropping below the underside of the rail. Thus, the magnetic railroad clip can stay engaged and/or pull tighter to the railroad track rail as a train passes over the rail.
