Built in the mid-1940s for Reading Railroad, this 40 boxcar had Damage Free loaders and was classed XMwa. Reading can be traced back to 1833 as the Philadelphia and Reading Railroad, one of the first railroads in the United States. Over time it became just Reading, and remained profitable through World War I. By the 1960s, declining profits lead to bankruptcy in 1971. In 1976, the remaining assets were merged with other railroads to form Conrail.
