A railcar door sealing assembly includes a first door seal member coupled to a first door plate of a first door of the railcar. The door sealing assembly also includes a second door seal member coupled to a second door plate of a second door of the railcar. The first door seal member at least partially overlaps with the second door seal member in a face-to-face relationship when the first door and the second door are in the closed position.

A railcar hatch cover assembly having a cover, a latch engaging structure, a latch coupled to the cover, and a handle coupled to the latch. The handle is configured to be grasped by an operator. When a substantially vertical force is applied to the handle, it moves the latch from a latched position to an unlatched position and moves the cover from a closed position to an open position. When the cover is dropped from the open position to the closed position, the latch contacts the latch engaging structure and moves from the unlatched position to the latched position. A railcar latch assembly having a latch coupled to the cover and a handle coupled to the latch. The latch has an arcuate bottom surface that contacts the latch engaging structure to move the latch from an unlatched position to a latched position.

Railroad hopper cars and methods of increasing total volume capacity of a railroad hopper car having a car body with two or more hoppers. In one embodiment, the railroad hopper car includes a car body having a pair of opposed sides and a pair of opposed ends defining a length. The hopper car additionally includes a pair of wheeled trucks supporting the car body. The hopper car further includes two or more spaced bulkheads extending between the pair of opposed sides to define three or more separate hoppers arranged adjacent one another along the length of the car body and between the pair of side walls. The hoppers being longitudinally asymmetric such that total volume of the hoppers on one side of a transverse center plane of the car body is different from total volume of the hoppers on the other side of the transverse center plane.

The present invention provides a railway wagon (100) comprising: a pair of bogies (106a, 106b), each bogie having wheels (108) configured in use to run on rails; a frame (104) supported by the pair of bogies (106a, 106b); and a bin (102) supported by the frame (104). The bin (102) has: a base portion (110) defining at least one catchment area (124); a substantially upright first end wall (114a); a substantially upright second end wall (114b) two longitudinal sidewalls (116a, 116b) extending between the first end wall (114a) and the second end wall (114b); an interior volume (118) for carrying product therein, the interior volume (118) being at least substantially defined by the first end wall (114a), the second end wall (114b), the two longitudinal sidewalls (116a, 166b), and the base portion (110); and an opening (120) opposite the base portion (110). The bin (102) is formed from at least two sections (103a, 103b) joined together, each section (103a, 103b) being formed at least substantially of composite materials and moulded as a single structure.

The present invention discloses a connecting rod type two-level locking device, a hopper car bottom door and a hopper car, and belongs to the technical field of rail wagons. The connecting rod type two-level locking device includes a transmission shaft, a door opening arm, a first roller, a second roller, a first locating pin, a standstill locking disk and a linkage mechanism. The hopper car bottom door includes the connecting rod type two-level locking device. The hopper car includes the bottom door. Even if the connecting rod type two-level locking device is accidentally stressed, the linkage mechanism cannot rotate, and at this time, the slave arm cannot rotate neither. The accidental opening of the hopper car bottom door can be avoided. The hopper car is more reliable to use.

According to some embodiments, a railcar comprises an underframe, a pair of sidewall assemblies, a pair of end wall assemblies, and one hopper bay formed between the pair of sidewall assemblies and the pair of end wall assemblies. The one hopper bay includes a longitudinal discharge opening extending the length of the hopper bay. The one hopper bay may extend the length of the railcar. The railcar may further comprise one or more longitudinal discharge gates coupled to the hopper bay and configured to cover the longitudinal discharge opening. The one or more longitudinal discharge gates are movable away from the longitudinal discharge opening, thereby allowing lading within the hopper to discharge through the longitudinal opening.
