Abstract
A heating system for railroad switches or other movable railroad structures that substantially eliminates protruding heater elements that may be damaged. The heater elements may cast into, enclosed within or received within recesses of a tie (including a metal or concrete tie), rail or other component. In one implementation, inductive heating is used to directly heat the rail, tie or other structure.
