Description
The TrainWorx 42885-02 is an N scale (1:160) 28-foot pup van trailer with converter dolly in Yellow Freight (Orange) livery — for prototype-correct LTL doubles configuration on layout highway and grade-crossing scenes.
Prototype: The 28-foot pup van is the standard short trailer used in LTL doubles (two pups behind one tractor, linked by a converter dolly) and triples (three pups) configurations — the workhorse of cross-country less-than-truckload freight. The converter dolly is a short single-axle frame with kingpin on top and fifth wheel that lets a second (or third) pup trailer connect behind the first.
Carrier: Yellow Freight System (founded 1924, Oklahoma City) — another of the iconic 'Big Four' US LTL carriers, instantly recognisable by the bright orange tractors and trailers with bold YELLOW branding. Merged with Roadway to form YRC Worldwide in 2003. Continued under the YRC and later Yellow Corporation names until ceasing operations in 2023.

About TrainWorx: US-based specialty manufacturer of prototype-accurate N-scale (1:160) highway vehicles — trucks, pup-van trailers, 53-foot trailers, and converter dollies — for layout scenes and grade-crossing dioramas.

Rubber tires and crisp printing make them indistinguishable from the real thing at scale viewing distances.
