Abstract
A railway car hatch cover includes an exterior shell cover, a gasket, and a mounting ring. The exterior shell cover has an outer-side and an under-side. The gasket is a vented gasket or a non-vented gasket, and the gasket is mounted to the mounting ring. The mounting ring is secured to the under-side of the exterior shell cover. The mounting ring is removable, and the gasket is replaceable with a second gasket. The second gasket can be vented or non-vented. The mounting ring is reinstallable on the under-side of the exterior shell cover. The replaceable gasket allows a single hatch cover to function as a vented hatch cover or a non-vented hatch cover depending on the type of gasket installed.
