40' ARC Box Car
Prototype Information
Freight car fans coined the term “Alternating Center Rivet” (ACR) to describe boxcars built with a distinctive side-panel design. Railroads used thinner side sheeting to cut weight, but this required extra interior posts for strength. The added posts created a second vertical row of rivets down the middle of each panel, spaced farther apart than those at the edges, which gave the sides a unique alternating rivet pattern.
No railroad embraced the ACR design more than the Union Pacific. In the late 1930s and into the years following World War II, UP rostered large numbers of 40- and 50-foot boxcars with this lightweight construction. The postwar groups stand out for modelers and historians because they capture a transitional period in freight car design, with changes to ends, roofs, paint schemes, and lettering that gave each class its own personality.
