摘要： A railcar comprises a hopper coupled to a discharge assembly. The discharge assembly comprises a discharge gate, a sloped side sheet, a gasket bracket, and a seal gasket. The sloped side sheet longitudinally extends above the discharge gate when the discharge gate is closed. The gasket bracket coupled to the sloped side sheet. The gasket bracket extends longitudinally along a bottom end of the sloped side sheet. The seal gasket is positioned between the sloped side sheet and the gasket bracket. The seal gasket has a straight section and a rounded section, such that a portion of the round section of the seal gasket is left beyond the bottom end of the sloped side sheet. The seal gasket creates a seal between the sloped side sheet and the discharge gate such that the weight of a lading increases the seal.

摘要： A system for a well car includes a frame, a hitch coupled to the frame near the first end of the frame, and a first deck coupled to the frame. The frame includes a first pair of sockets located near a first end of the frame and a second pair of sockets located near a second end of the frame. Each socket of the first pair of sockets is configured to engage a support casting of a first pair of support castings located at a first position along a length of a well car. Each socket of the second pair of sockets is configured to engage a support casting of a second pair of support castings located at a second position along the length of the well car. The first deck is configured to hold wheels of a trailer when the trailer is coupled to the hitch.

摘要： According to some embodiments, an autorack railcar comprises first and second ends, and first and second longitudinal sides disposed between the first and second ends. The longitudinal sides comprise a plurality of side posts. The railcar further comprises a rack for transporting vehicles enclosed by the ends and sides. A first width of the railcar between the longitudinal sides proximate a center of the railcar comprises a first width value. A second width of the railcar between the longitudinal sides between the center of the railcar and either the first or second ends comprises a second width value greater than the first width value. The side posts positioned within the second width of the railcar have a width that is less than a width of the side posts positioned within the first width of the railcar.

摘要： According to some embodiments, a railcar comprises a center sill extending along a longitudinal centerline of the railcar, and two side sills. The two side sills are on opposite sides of, and extend parallel with, the center sill. The railcar further comprises a first inner discharge door coupled to the railcar proximate the center sill on a first side of a longitudinal centerline of the railcar (first side); a second inner discharge door coupled to the railcar proximate the center sill on a second side of the longitudinal centerline (second side); a first outer discharge door coupled proximate the side sill on the first side; a second outer discharge door coupled proximate the side sill on the second side; a first linkage coupling the first inner discharge door to the second outer discharge door; and a second linkage coupling the second inner discharge door to the first outer discharge door.

摘要： Cellulose nanofibers (CNF) act as a dispersing agent to directly exfoliate graphite in an aqueous solution using sonication. The resulting suspension has graphite flakes, each having 2-20 monolayers, a relatively large lateral dimension, and a plurality of CNF decorating its surfaces and edges. The dispersing effect of the CNF allows the graphite-CNF suspension to be stored without degradation until desired use. The graphite-CNF suspension can be used to form various composite structures, such as by spraying, coating, pouring, extruding, or printing the suspension, and then drying the suspension. The resulting composite structures have improved tensile strength and toughness due to hydrogen bond interactions between the CNF and graphite.

摘要： A railcar backup cooling system may be added to an existing railcar (e.g., a boxcar) to provide supplemental or backup cooling to the railcar in the event that an HVAC failure or other circumstance occurs, which causes the interior temperature of the railcar to rise. The system includes a container of liquid or compressed gas mounted on the railcar, a valve controlling the flow of the liquid or gas from the container, and a controller configured to open the valve when the HVAC system fails or is otherwise unable to maintain the railcar at the desired temperature. When the valve is opened, the liquid and/or gas stored in the container may exit, expanding into a cool gas and thereby acting to cool the railcar environment.

摘要： A modular autorack system includes a flatcar, first and second fixed ends, a coupling apparatus coupled to the flatcar, and an autorack module. The first fixed end is coupled to the flatcar at a first end of the flatcar. The second fixed end is coupled to the flatcar at a second end of the flatcar, opposite the first end. The autorack module is configured to detachably engage the coupling apparatus. The autorack module includes a floor panel configured to transport at least one vehicle, a first open end, and a second open end. The second open end is opposite the first open end. The first fixed end is configured to cover the first open end and to prevent a vehicle from exiting the autorack module through the first open end when the autorack module is engaged to the coupling apparatus and positioned between the first and second fixed ends.
