摘要： A plate assembly for securing a rail to a tie that includes a clip and a shoulder with an orifice. At least one of the clip and the shoulder are modified by changing their respective shape to form a positive interference fit therebetween. The modification is provided to ensure that the clip is maintained with its leg partially inserted into the shoulder orifice during staging.

摘要： A swing railroad turnout that includes a railroad track with a mobile portion and actuators that are used to selectively bend the mobile portion between a first and a second position. In the first position, connection is made to a first track. In the second position, connection is made to a second track. The tracks are formed of rails that are supported on ties or other fixed foundations. The rails are either bent with respect to the ties, or the ties themselves are moved generally transversely to bend the rails. Connecting mechanisms are provided for selective connection of the rail ends.

摘要： In a railroad system a track includes ties positioned at predetermined intervals and supporting a pair of rails. Shoulders are disposed in pairs adjacent to the sides of each rail and are partially imbedded in the ties to limit the lateral movement of the rails and define the track gauge. Over time, friction between the insulators and the shoulders may cause excessive wear and a gap therebetween. This wear is compensated by a shim attached to the shoulders.

摘要： Typically, a tie plate assembly for supporting a rail on a tie includes a tie plate and a spike that is driven through the plate into the tie to secure the tie plate to the point. A sleeve is provided on the plate that is inserted into a tie to prevent the deflection of the spike with respect to the ties wheels of a train pass over the tie.
