Abstract
A rail heating assembly including a series of individual heating modules is operable to raise and maintain the temperature of rails of a railroad track to reduce bending and deforming of the rails due to variations of atmosphere conditions. The heating module includes a series of burners with attached radiator plates so as to provide convective and radiant energy to heat the rails. The heating module includes an outer shell and a Venturi-shaped inner shell to surround the rail, with a series of burners attached to one end providing a stratified flame to heat the rail. A series of radiator plates mounted to the inner shell are heated by the flame, and the radiator plates radiate thermal energy towards the rail.
