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.

摘要： A fastening system configured to attach railroad crossties to one or more support structures such as the girder of a bridge. The fastening system includes a plate mounted on a crosstie and a clip attached to the plate that is configured to provide a force between the support structure and the crosstie and secure the crosstie in place.

摘要： A pad for a railway rail fastening assembly, the pad being configured for placement between a rail and an underlying foundation, such as slab track or a sleeper, wherein a cross-section of the pad comprises: a second resilient layer configured to face a railway rail; an intermediate rigid layer; and a first resilient layer configured to face an underlying foundation. The rigid layer is provided between and is integrally formed with the first and second resilient layers. An edge of the pad comprises at least one ear that extends beyond a central region of the pad, the rigid layer extending into the ear with the ear being configured to resist rail roll.

摘要： A rail pad can have a major face forming a railseat portion on which a foot of a railway rail sits when the pad is in use, the railseat portion having opposite side edges to at least part of each of which a respective upstanding portion of the pad can be connected, wherein the pad does not have any part which extends laterally from the railseat portion in a same plane as the railseat portion. The respective upstanding portion can be connected to a projection of the rail pad which extends laterally from the respective upstanding portion such that the projection can be vertically spaced from, and does not overhang, the railseat portion, the projection spaced from ends of the respective upstanding portion such that the projection can be configured to interlock with a corresponding opening in a front part of one of the railway rail clip anchoring devices.

摘要： A fastening system or apparatus for securing a rail to the underlying railroad tie includes a pad, two insulators attached to the pads and two shoulders attached to the ties. An interference fit is formed between the insulators and the shoulders to capture the pad between the shoulders. The insulators are pre-attached to the pad. The mating protrusions of the shoulders and pad allows for ease of insertion such that the pad assembly can be shipped together with the underlying tie.
