In a method of preventing snow from bedding into railway switches, air is blown into the area between the stock rail and the movable rail in a switch, and substantially horizontally in a direction obliquely outwards towards the open end between the stock rail and the movable rail. An apparatus for carrying out this includes a blower assembly (8) between the rails in a railway switch, the assembly being supplied by a fan unit (20) and adapted to provide a substantially horizontal air discharge directed obliquely outwards towards the open end between the stock rail and the movable rail in their separated positions. |
