The Baltimore and Ohio M-53 Wagontop Boxcar is a true signature classic! In an era when the major design elements of the 40' boxcar seem to have been well standardized, the Baltimore and Ohio employed an innovative design in which the roof and sides were constructed from single panels of cooper-bearing steel. The quality of this steel and the seamless roof design protected lading from roof leaks and made these cars battleships on the rails. Some of these cars remained on the rails up to the early eighties. ExactRail's M-53 Wagontop Boxcar has been designed, engineered and tooled in the U.S. Our unique approach to precision micro-tooling distinguishes the M-53 in the numerous fine scale details.
