ABSTRACT:
A deck double plug assembly for plugging first inboard and second outboard deck holes in the deck of converted railroad autorack cars comprises a first plug connected to a second plug base assembly by a connector portion. The second outboard plug assembly is clamped to the deck to cover and plug the second outboard deck hole, whereby the deck plug assembly may be installed by one person. The method of installation from the top surface of the deck includes the steps of loosely assembling the second outboard plug assembly, holding the second deck plug assembly and pushing the first plug downwardly through the second outboard deck hole, inserting the first inboard plug into the first deck hole from underneath the deck, and clamping the second plug assembly to the deck surrounding the second deck hole.
