The Mark IV Flexi-Van Flatcar from Trainworx is based on the late-1950s-built intermodal flatcars that hauled special trailers with removable bogies. They could be seen on piggyback trains as well as in passenger consists on lines looking to boost revenue of their passenger trains. This layout-ready Mark IV Flexi-Van Flatcar features a detailed body, accurate decoration, metal wheels and magnetic knuckle couplers.
