  • Patent number: 11958509
    Abstract: A hopper railcar includes a plurality of hoppers for carrying material laden material, wherein each hopper has a lower discharge chute formed by converging side sheets and end sheets defining a transverse opening; and pivoted transverse door for each transverse opening for selectively opening and closing and closed by a pivoted door, the pivoted door having a pivot axis perpendicular to a longitudinal length of the railcar, and lateral deflectors on lateral sides of the doors with each of the deflectors having a side face extending above an interior facing surface of the doors upon which laden flows with the door in the open position. A method of retrofitting hopper railcars to include deflectors is also disclosed.

  • Publication number: 20110179969
    Abstract: A open top railcar comprises a pair of spaced trucks, a railcar body supported on the trucks, the body comprising a pair of side structures on opposed sides of the railcar and a pair of end structures on opposed ends of the railcar, and a top chord extending the length of the side structures and the width of the end structures, wherein the top chord includes an inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. The railcar may further include corner cap, or end cap members, with each corner cap, or end cap including inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. The railcar may be a hopper railcar having a plurality of discharge chutes forming pockets for the body which open to the interior with a plurality of door operated through a pneumatic door operating system and further including a manual door operating override for each door.

  • Patent number: 7832340
    Abstract: The door operating system of the present invention can be applied to new railcar or retrofitted to existing railcar designs. The hopper car will have a pair of doors on opposed sides of the center sill which are connected through a door spreader. The pneumatic, individual door operating system is connected to the door spreader through an adjustable spreader fulcrum in which the sliding adjustment may add in a proper connection force or tension between the door operating system and the individual doors.
