Abstract
A device for moving a tongue rail of a railway switch, comprising at least two rollers arranged one behind the other and substantially parallel to the course of the rail, on which rollers the tongue rail can roll up from a lower abutting position on the stock rail and directly in front of the first roller onto the first roller, and can roll on to another roller until the tongue rail reaches an open switch remote, wherein at least one additional intermediate roller that is smaller than the rollers, is provided in the space between the rollers, and wherein the axis of rotation of the intermediate roller is arranged substantially parallel to the axes of rotation of the rollers.
