40' Plug Door Refrigerated Box Cars
Otherwise know as an insulated box car some of these have under frame refrigerator units mounted on the underbelly, however most were just "insulated" from wide temperature changes. Used for beer, meat or packaged good to steel auto parts. Identified by the large thick door that actually "plugs" into the wall of the body. Note: Cars are available in 2 or 4 number variations.
