The Atlas Master N Scale NACC 50' Smooth-Side RBL Insulated Boxcar is based on cars that hit the rails between 1963 and 1965 and lasted into the early 2000s. Built at the Chicago Ridge plant of North American Car Company (NACC) produced nearly 750 of their first homegrown RBL, an inside post, or smooth-side car. Effectively a transitional design between the Pacific Car and Foundry offset door cars, and the later, and more commercially successful, outside post RBLs, this car featured a centered plug door and was only available in a single 50'-1" interior length. Though not as numerous as the outside post variations, as lease cars, they could be found sporting numerous colorful paint schemes. This model features accurate schemes and free-rolling trucks with knuckle couplers. NACC 50' Smooth-Side RBL Insulated Boxcars are part of the line of Atlas N Scale boxcars.
