Abstract: A heater for a railroad track switch using forced hot air to heat the area between the moving and fixed rails to maintain the area free of ice and snow, and to heat the side plates and maintain them free of ice and snow, including duct work and distribution outlets for distributing hot air evenly over the entire switch length in the areas where the elimination of snow and ice will permit the movable rails to operate freely and easily.
