Rapido Trains HO Scale Duplex Sleeper is based on Canadian Car & Foundry cars ordered by Canadian National in the early 1950s. The cars are also similar to equipment found on many North American railroads from 1940-1980. Each comes prepainted and lettered, with several different numbers or names for each scheme to easily build a larger consist. Cars are fully assembled and include a detailed underbody with separate steam, air and electrical lines, flush-fitting windows with raised and painted window frames, factory-applied grab irons and uncoupling levers, fully detailed interior cast in appropriate colors, rack-powered interior lighting, separate, removable marker lamps and end gates and operating diaphragms with supports. Super Continental Line cars feature improved design and assembly to prevent warping, tighter connections between the body and the roof, new couplers designed for more reliable operation when pulled or pushed and redesigned, free-rolling trucks. Cars will negotiate 18′ radius curves 24′ or greater is recommended. The Duplex Sleeper is part of the line of Rapido HO Scale passenger car models.
