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.
