WalthersProto HO Scale Express Boxcars (Converted Troop Cars) is based on widely used conversions. During World War II, when American Railroads{ passenger car fleets were stretched to the limits, Pullman Standard and American Car & Foundry stepped up and filled out the nation{s fleet. Essentially 50' boxcars on passenger-style trucks, the cars featured simplified interiors and were used by the military to move troops across the country. After the war, there was no longer a need for these spartan passenger cars and they were sold to several railroads at bargain prices. Most of the cars had their interiors removed and windows plated over for service as Express Boxcars. Many of these cars could be found on the headend of passenger trains into the 1960s.
