Atlas Master Series N Scale 50' Smoothside RBL Box Car

Between 1963 and 1965, the Chicago Ridge plant of North American Car Company (NACC) produced nearly 750 of their first homegrown RBL, an inside past, or "smoothside" car. Effectively a transitional design between the Pacifc 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 throughout their long lifetimes from the 60s through the early 2000's
