发明名称 Railroad track switch covers and heater
摘要 A heat retaining and snow deflecting cover assembly for railroad track switches is made up of panels that prevent snow and ice from building up in the regions where the switching rails must move. An inner panel assembly is mounted between the switching rails near the entry point of the track switch. Outer panels are secured along the outer sides of the main tracks. The panels also retain heat generated by conventional heaters. Deflecting panels are secured at both ends of the inner panel assembly to guide snow inwardly to the center of the track and away from the switching rails. The cover assembly is easily installed for winter use and removed when no snow is present.
