Walthers Mainline 910-46617 | 50' AAR Improved Double-Door Boxcar - Cushioned Underframe - Union Pacific UP #160118 | HO Scale

The Walthers Mainline 910-46617 brings a 50' AAR Improved Double-Door Boxcar in classic Union Pacific paint to your HO layout. Lettered as UP #160118 in UP's signature Armour yellow with red trim, this car is the unsung workhorse that hauled appliances, auto parts, and any other large cargo that needed dock-level loading on both sides of a 50-foot car — the cushioned underframe protected loads from coupling impacts in classification yards.

What era is this car appropriate for?
Postwar / transition through modern. The 50' AAR Improved Double-Door design appeared in the 1950s and many cars stayed in service through the 1980s — perfect for any UP layout from the late steam era forward.

What was it used to haul?
Anything that needed the extra-wide 16-foot door opening — appliances, auto parts, machinery, large crates, and other lift-truck-loaded cargo. The cushioned underframe also made it a favorite for fragile loads.

Are couplers and wheels included?
Yes — the car ships ready-to-run with knuckle couplers and metal RP-25 wheelsets. No upgrades needed.

Does it work with all HO track?
Yes. Walthers Mainline cars roll on all NMRA standard HO track systems — code 100, code 83, and code 70.
