Cover assemblies for railroad cars are disclosed. In some embodiments, the cover assemblies include a cover pivotably movable between closed and open positions. The cover assemblies additionally include a lid stop assembly including a release handle positioned adjacent to a cover handle and a first locking element operatively connected to the release handle. The lid stop assembly additionally includes a second locking element attached to, or formed with, the housing. The first locking element moves between a locking position in which the first locking element engages the second locking element to secure the cover in the open position, and a releasing position in which the first locking element is spaced from the second locking element allowing the cover to be moved from the open position toward the closed position. The release handle allowing the user to move the first locking element between the locking and releasing positions.

Cover assemblies for railroad cars

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.
