  • Patent number: 9937933
    Abstract: A trapdoor assembly for use on railcars is provided. The trapdoor assembly is pivotable between an up position and a down position. In the up position, the trapdoor assembly provides access to stairs on the railcar so that passengers can egress between the railcar and a ground level platform at a rail station. In the down position, the trapdoor assembly covers the stairs and provides a platform so that passengers can egress between the railcar and an elevated platform at a rail station. The trapdoor assembly also includes an extendible platform for bridging the gap between the railcar and the elevated station when the trapdoor is in the down position and the railcar is stopped at the elevated station.

  • Patent number: 8011306
    Abstract: A railroad car truck for a railroad freight car, such as an autorack car, has a bolster mounted cross-wise between two sideframes. The bolster ends are mounted on respective spring groups carried by the sideframes. The bolster can translate laterally relative to the sideframes. The side frames are mounted to swing laterally relative to the wheel sets, and hence relative to the rails. Resistance to lateral deflection is provided by the resistance of the sideframes to the pendulum swinging motion, and by shear in the spring groups. The truck has a doubled damper arrangement of dampers in a four-cornered layout at each end of the bolster, giving a flexing resistance to yaw between the sideframes and the bolster ends. The doubled damper arrangement works against large wear plates mounted on the sideframe columns. The large wear plates are mounted normal to the dampers and square to the sideframes.
