Product Overview

The 1937 AAR 40' Boxcar became one of the most successful freight car designs in North American railroad history. Nearly 94,000 examples were constructed for dozens of railroads beginning in 1936, making these cars a familiar sight hauling everything from manufactured goods and paper products to machinery and general merchandise. Thanks to rebuilds, upgrades, and secondhand ownership, many remained in service well into the 1980s.

While built to a common Association of American Railroads (AAR) design, these cars appeared on railroads across the United States and Canada with countless variations in ends, roofs, doors, ladders, brake equipment, and other hardware. Their versatility made them true workhorses that could be found in virtually every type of freight service.

Rapido's highly detailed model faithfully captures the many subtle prototype variations found on these iconic cars. From the correct end styles and roof options to finely rendered underbody details and crisp lettering, these HO Scale models are ideal for steam-era, transition-era, and early diesel-era layouts. Whether operated individually or assembled into longer freight consists, they deliver the outstanding quality and prototype accuracy Rapido is known for.
