Universal slide-plate
A universal slide-plate includes a body and a drop-in shoulder member with a plurality of retaining members that cooperate to selectively connect the universal slide-plate and a stock rail to a rail platform and/or tie. The universal slide-plate has a slide surface configured to support a moveable point rail thereon. The universal slide-plate may be selectively removed and repositioned relative to a rail platform and/or tie.
System, method and support element for actively damping acoustic vibrations of a rail for rail traffic
A system for actively attenuating acoustic vibrations of a rail for rail traffic is provided including at least one sensor for detecting at least a vertical acoustic vibration of the rail, at least one actuator for exciting at least a vertical counter-vibration of the rail and at least one control unit communicatively connected to the at least one sensor and the at least one actuator for controlling the at least one actuator depending on the vibration detected by the sensor, the counter-vibration being adapted to destructively interfere with the detected vibration, and the at least one actuator being mechanically coupled to the rail and to a carrier element supporting the rail. Also provided is a carrier element for the system and a method for actively attenuating acoustic vibrations of a rail for rail traffic.
Guide plate and rail attachment point
The invention relates to a guide plate for laterally guiding a rail in a rail attachment point formed on a railroad tie, wherein the guide plate has a top side having a support surface for supporting a spring element, an underside, by way of which the guide plate is supported on the railroad tie during use, a support segment having a support surface, by way of which the guide plate is supported, during use, on a shoulder provided on the railroad tie, and possesses a guide segment which is formed opposite to the support segment, and on which a guide surface is present, on which a rail is laterally guided during use. In order to counteract twisting of the rail and concomitantly the risk of the occurrence of track warping at high outdoor temperatures when using such a guide plate in a rail attachment point, a latch projection is formed in lateral end segments of the guide surface, in each instance, projecting away from the guide surface in the longitudinal direction of the guide plate, which is provided for the purpose of engaging, during use, under the longitudinal side of the rail that is assigned to the guide surface, in each instance, wherein the distance between the latch projections amounts to at least 60% of the width of the guide surface.
