Piggyback trailer service was developed in the 1950's to offer faster movement of goods to market and to counter the growing over the road trucking industry. With many of the original developments made by the Pennsylvania Railroad, including the formation of the Trailer Train Company, which would later become TTX.

The idea was simple, load trailers on flatcars. It was more complicated than that and many developments and improvements were made over the years. In the early days, trailers were driven, or towed into place on the flatcars. Many flatcars had bridge plates that were lowered into place during loading allowing trailers to be moved up loading ramps and across multiple flatcars to their assigned spots.

Eventually, as container use increased, piggyback trailer transport was surpassed. However it still remains an important part of freight movement today.

Many major shippers use Piggyback, or as they are more widely known today, Trailer On Flat Car (TOFC) transport to get their goods to regional or local transfer points for last mile truck delivery. Examples include UPS and FedEx.

Based on PRR Class F39A built especially for Piggyback Service, these cars were used from 1955 into the 1990's. They carried trailiers, containers and other types of loads.
