Abstract

An air blowing system for use in keeping railroad track switches clear of snow utilizes flexible tubes, preferebly of rubber or plastic, located transversely beneath the main tracks, and connecting with resilient nozzles to direct a high flow of air in the direction of the track switch points. The system may include resilient ducts conveying air in protective relation with the switch control rods extending laterally beneath the track.
The rod protective air discharge may be by way of a louvered cross-tube, extending parallel with the rods, to discharge air laterally of the rods, or one or more nozzles discharging air longitudinally of the rods.
