摘要： According to some embodiments, a railcar comprises a well component disposed between a pair of trucks. A pair of end sections are disposed at each end of the railcar. An end section comprises a well platform disposed near an end of the well component; an end platform disposed near an end of the railcar; and a connecting platform extending between the end platform and the well platform. A pair of ladders may be coupled to each end of the end platform. A first handrail may extend between the ladders and along an outside edge of the end platform. A second handrail may extend from a ladder, along an inside edge of the end platform, along an edge of the connecting platform, and along an inside edge of the well platform. A third handrail may extend along an edge of the well platform adjacent to the well component.

摘要： According to some embodiments, a refrigerated railcar comprises a pair of side walls, a roof, a floor, and a refrigeration unit. The floor comprises a bottom structure comprising a plurality of channels for return air flow from an interior of the railcar to the refrigeration unit. The floor further comprises at least two top plates coupled to the bottom structure (e.g., via a pivot rod). Each of the top plates extends longitudinally along the bottom structure and is configured to rotate up and away from the bottom structure proximate one of the side walls of the pair of side walls. Lifting an edge of a top plate opposite the edge of the top plate pivotally coupled to the bottom structure causes the top plate to rotate to an upright position exposing the plurality of channels of the bottom structure.

摘要： A door assembly for a railcar includes a sliding system and a latching system. The sliding system is operable to slide the door to a side of the entrance of the railcar to provide an opening path to an entrance of the railcar. The sliding system comprises one or more rollers used for sliding the door. The latching system is operable to plug the door to the railcar such that the door moves inward toward the railcar, and unplug the door from the railcar such that the door moves outward from the railcar. The latching system comprises a lever operably coupled with two or more gears. The lever turns a particular number of rotations in a first direction to plug the door to the railcar. The lever turns the particular number of rotations in a second direction to unplug the door from the railcar.

摘要： A side wall for a railcar includes a plurality of integrated side sheets. Each of the integrated side sheets includes a sheet of metal having a top side edge and a bottom side edge extending from a first end to a second end of the sheet of metal. The sheet of metal further includes a flat area portion extending a first distance from the first end towards the second end between the top side edge and the bottom side edge. The sheet of metal further includes a side post portion adjacent to the flat portion, the side post portion comprising a plurality of bends forming a recess. The plurality of bends forming the recess includes at least a first bend, a second bend, a third bend, and a fourth bend. Adjacent integrated side sheets may be coupled together to form the side wall.

摘要： An assembly that includes a housing with a chamber formed within a bore of the housing. The assembly further includes a tapered center shaft disposed at least partially within the bore of the housing. The chamber includes an angled contact surface, a sliding wedge, and a load spring. The sliding wedge is positioned to apply a force onto the angled contact surface of the chamber. The sliding wedge is also positioned to apply a frictional force to a rod portion of the tapered center shaft. The load spring is compressed between a contact surface of the chamber and a contact surface of the sliding wedge. The load spring is positioned to apply a compressive force onto the contact surface of sliding wedge toward the angled contact surface of the chamber.

摘要： According to some embodiments, a railcar comprises: an underframe comprising a center sill extending longitudinally along a centerline of the railcar; a hopper coupled to the underframe and comprising a discharge opening; and a discharge assembly coupled to the hopper. The discharge assembly comprises: a sloped side sheet, and a discharge gate frame in a plane offset from horizontal and extending from a bottom of the sloped side sheet to proximate the center sill. The discharge gate frame at least partially surrounds the discharge opening. The discharge assembly further comprises a discharge gate coupled to the discharge gate frame. The discharge gate is operable to move from a closed position that restricts a lading from discharging to an open position that permits the lading to discharge. Moving from the closed position to the open position comprises moving at an angle upward and transverse to the railcar.

摘要： An assembly that includes a housing with a chamber formed within a bore of the housing. The assembly further includes a center shaft disposed at least partially within the bore of the housing. The chamber includes a backing wedge, a sliding wedge, and a load spring. The sliding wedge is positioned to apply a force onto an angled contact surface of the backing wedge. The sliding wedge is also positioned to apply a frictional force to a rod portion of the center shaft. The load spring is compressed between a contact surface of the chamber and a contact surface of the sliding wedge. The load spring is positioned to apply a compressive force onto the contact surface of sliding wedge toward the angled contact surface of the backing wedge.
