Induction Coil Driver Card for a Railroad Switch Heater System
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.

Inductive Rail Heating Head for a Moving-Point Train Track Rail and a Fixed Train Track Rail
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.

Magnetic Inductive Rail Heating Head
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.
