45' TRAILER MODEL FEATURES: Separately applied mud flaps Rubber tires Fully-assembled and ready to use out of the box Highly-detailed, injection-molded body Painted and printed for realistic decoration   PROTOTYPE HISTORY: Trailer On Flat Car (TOFC) has been in service since the 1940s when it was originally developed to load truck trailers onto flat cars to streamline service and minimize transferring cargo from boxcars to trailers. In the early 1980s, after the railroads were deregulated, TOFC service exploded in North America. The railroad's ability to adjust haul rates to be competitive with trucking meant new revenue in areas that the railroads weren't able to successfully compete before.
