Abstract: The subject of the present invention is a mechanism for operating sets of switch points, comprising an actuator control assembly (1) actuating two points operating half-bars (2), each connected to one point blade (switch rail), by a point-setting device (3) and by a manual control (4) connected in the actuator control assembly (1). The mechanism is one wherein actuation of the two points-operating half bars (2) by the actuator control assembly (1) is performed by way of rotary cam-drive devices (5), each one assigned to one operating half-bar (2) and wherein the points-setting device (3) is a device independent of the points-operating half-bar (2) and controlled by the actuator control assembly (1). The invention applies more particularly to the field of railway (railroad) infrastructure, particularly the operating of switch points.

Abstract: A crossing frog includes: a cradle assembly which includes a movable point fitting component which has two projection elements which are mutually spaced-apart, a movable point which is mounted in the cradle assembly and fitted in the fitting component, spacer components which are interposed between the projection elements and the movable point, and accommodation for removably fixing the movable point in the fitting component. The spacer components are fixed to the projection elements in a removable manner by the accommodation for removable fixing so that it is possible to remove the point in a vertical direction relative to the cradle assembly.

Abstract: The stretch of rail comprises a railway switch element (12) made from high-alloy steel, in which at least one alloy element has a content equal to at least 5% by weight, and a length of rail (14) made from steel, connected to one another by a weld without deposition of metal. The length of rail (14) is formed from a medium-alloy low-carbon steel of which the carbon content is less than 0.55% by weight.

Abstract: A movable point for a crossing frog for railway apparatus of great length, incorporated in long welded rails. The point (7) is comprised of a single steel element, which comprises integral seating cross members (8). The rigidity of the point varies along all its length from a minimum adjacent a thin forward portion (9) to a maximum adjacent a wide rear portion (10). The point is constituted by a piece of austenitic manganese steel. The point can be of cast steel or can be formed by laminating and/or forging, followed by machining.
