A hatch cover assembly includes a vent passageway through a hatch cover for venting the interior of a railroad hopper car, or the like, to the environment. The hatch cover is held in closed position by a locking strap, and the vent passageway is located directly beneath the locking strap to help prevent rain and other environmental contaminants from passing through the vent passageway. An inexpensive baffle assembly is releasably clipped into the vent passageway beneath the locking strap and is comprised of a two piece molded plastic structure with a mesh screen held therebetween to further protect the vent passageway from contaminants.
