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.

An induction coil driver card for a railroad switch consists of a main power supply, a control unit, at least one induction heating unit, and an interface driver. The main power supply is electrically connected to the at least one induction heating unit that is used to generate eddy current fields. The generated eddy current field excites the atoms within the railroad switch resulting in elevated temperatures. The power input to the induction heating unit is managed via the control unit. The interface driver allows the user to control the frequency ranges received by the induction heating unit by utilizing the control unit. The interface driver also allows the user to have remote access via a wireless cellular modem.

A heating device for removing snow or ice that accumulates in between a moving-point train track rail and a fixed train track rail consists of an induction coil, a holding case, and a mounting tray. The induction coil is positioned within the holding case which is then positioned on the mounting tray. For optimal performance, the mounting tray is positioned adjacent a planar bottom surface of both the fixed train track rail and the moving-point train track rail. The eddy current field of the induction coil excites the atoms within the steel which then results in elevated temperatures. The heat radiated from the fixed train track rail and the moving-point train track rail removes any accumulated snow or ice.

A rail heating head includes a vented enclosure and an induction coil. The induction coil is positioned within the vented enclosure. When in use, the vented enclosure is positioned adjacent a lateral portion of a train track rail. To be positioned adjacent to the head, the web, and the foot of the train track rail, a rail-bracing wall of the vented enclosure has a convex exterior surface and a concave interior surface. The induction coil has an oblong, concave shape and is pressed against the concave interior surface. Thus, the induction coil can induce eddy current magnetic fields in the head, the web, and the foot maximizing surface area. The larger surface area results in molecules in a large area being activated and leads to more heat. An eddy current deflecting magnetic shield further directs magnetic fields towards the train track rail.
