  • Patent number: 12077195
    Abstract: Manway assemblies for railroad tank cars are disclosed. In some embodiments, the manway assemblies include a cover having a perimeter portion with a plurality of spaced grooves. The manway assemblies additionally include a plurality of spaced fasteners pivotably attached to the nozzle adjacent to the opening. The manway assemblies further include an interference member attached to the cover adjacent to at least one groove. The interference member prevents pivoting of the at least one fastener from a secured position in which the fastener is received in a corresponding groove, to an unsecured position in which the fastener is spaced from the corresponding groove when the cover is in a closed position. The interference member allows pivoting of the at least one fastener from the secured position to the unsecured position when the cover is in a partially open position in which pressure contained within the railroad tank car is vented.

  • Patent number: 12024211
    Abstract: A railroad hopper car having a single cargo-receiving hopper extending over substantially the length of a car body having a cargo discharge portion occupying most of the available distance between the wheeled trucks supporting opposite ends of the car body. The car has no pair of slope sheets separating longitudinally-adjacent hoppers and defining unusable space beneath the slope sheets, and so the overall length of such a hopper car capable of carrying a desired volume of cargo can be less than that of one with multiple separate hoppers. Cargo discharge openings are arrayed along the length of the cargo discharge portion, and a unitary multi-gate assembly is supported within the cargo discharge portion of the car body so as to be movable longitudinally of the car body to open or close all of the cargo discharge openings simultaneously.
