HO Rivarossi NMRA Pacific 4-6-2 Steam Locomotive Set with 4 Passenger Car New OS. This listing is for a new old stock. HO gauge Rivarossi set celebrating NMRA National Model Railroad Association. The set consists of a 4-6-2 Pacific steam locomotive and 4 passenger cars. I have tested the locomotive and it runs smoothly in both forward and reverse and is lighted. The 4 passenger cars all have full interiors. The boxes for the cars are very interesting. Three of the boxes are brown and stamped with the cars that are inside. They are actually Rivarossi boxes that the NMRA turned inside out and stamped with the contents. The steam locomotive comes in it’s original Rivarossi box. The cars are: Baggage Post Office Car “Lookout Mountain” Dining Car “James J Andrews” Pullman Coach (Rivarossi Box) “Missionary Ridge” Observation Tail Car. The set is in excellent condition. Please see the photos. A very handsome and pretty scarce set. Please see my other listings for more interesting trains. Please see photos as that is part of the description. One for the loco the other for the cars. Get images that make Supersized seem small. Showcase your items with Auctiva’s. Track Page Views With.
