There is a grey wagon with Union Pacifc Markins, fully complete with buffers and Playcraft/Hornby Dublo type couplings, and a yellow wagon, with no markings. This second wagon has a full set of buffers but no couplings - though Playcraft type could be very easily screwed in place as mounting points exist under the chassis.
The "Two USA closed wagons (ferry wagons)" product is ideal for HO modelers looking for authentic additions to their layouts, as they provide a realistic and detailed representation of the type of wagons commonly found on ferries or freight boats in the United States.
