ABSTRACT OF THE DISCLOSURE A system for moving freight carriers including high- way semi-trailers and receptacles such as demountable containers and merchandise racks in trains on railway tracks includes railway trucks having two wheeled axles supporting a truck frame which has an elongated central longitudinal member for slidably receiving the base of a fifth wheel pedestal to permit its positioning at different locations lengthwise of the truck frame, and a pair of longitudinally disposed structures for supporting the highway wheels of semi-trailers, the highway wheel support- ing structures each including a pair of transversely spaced longitudinally extending treadways supported on the truck frame and connected by a transverse element which underlies the longi- tudinal central member and is pivoted to the truck frame to accommodate limited swiveling of the respective wheel support structure, the treadways being spaced apart sufficiently trans- versely of the truck to accommodate the base of the fifth wheel support structure such that the highway wheels of a semi-trailer can be supported on the treadways of one wheel supporting struc- ture and the fifth wheel support can be positioned abreast of the other highway wheel supporting structure to support the king pin of another highway semi-trailer in front to rear end to end relation with the first-named trailer, a plurality of trailers and railway trucks being linkable into a train, with the king pin of the front semi-trailer supported on the fifth wheel support of a road-rail tractor. For positioning the highway wheels longitudinally of the wheel supporting structures on the railway trucks, each of the treadways is provided with a fixed chock at its inner end and a demountable shock at its outer end to permit movement of the highway wheels on to and off the wheel support structure. For supporting and securing demountable containers or merchandise racks on the truck, a pedestal support is hinged to the outer side of each treadway to permit it to swing clear of the treadway when semi-trailers are loaded or unloaded and moved into container or rack supporting and secur- ing position on the treadway and locked thereon and to the container or rack.
