A series of relatively lightweight, short, articulately interconnected cars is disclosed for transporting trailers or other cargo containers on a railway. The interior cars of the series include a center sill which constitutes a narrow width underframe and a length substantially equal to the length of a car, a pair of end sills connected perpendicularly to the center sill at opposite ends thereof and having a width extending beyond each side of the center sill, support members interconnecting the ends of the end sills with the center sill, and male and female portions of an articulated connector respectively attached to each end of a car. End cars have one end, constructed similarly, but are provided with conventional semi-automatic couplings on the other end in place of a portion of the articulated connector. The articulated connectors are mounted on a single conventional railway truck which spans the adjacent ends of interconnected cars and further supports the support members. Special configurations of the cars are disclosed for use in a trailer-on-flatcar (TOFC) and container-on-flatcar (COFC) environments.
A railway car comprising at least two railway car units connected end to end by an articulated connector having mating male and female members, said ends of said car units being mounted on a single truck assembly which spans the space between said ends, each of said car units comprising a center sill which extends substantially the entire length of the car unit, a first of said mating members of said articulated connector fixed to one of said car units and a second of said mating members fixed to a second of said car units, an end sill disposed transversely on each of said car units and extending substantially symmetrically from the center sill, a side bearing support member extending from respective sides of the center sill at points spaced from the said end of each car unit and extending longitudinally between car units, said single truck assembly comprising a pair of side frames holding a pair of axles having wheels mounted thereon, a truck bolster disposed between and extending substantially parallel to said axles for supporting said articulated connector, a side bearing support member on said bolster on opposite sides of the longitudinal axis of the bolster, and one pair of side bearings disposed on each of said bearing support members, each pair of side bearings on the same side of said longitudinal axis of the bolster supporting said pair of side bearing support members of one of said interconnected car units.
A railway car comprising a series of railway car units connected end to end by articulated connectors having male and female mating members, a single railway truck assembly which spans the space between adjacent car unit ends with adjacent ends of said railway car units mounted thereon, each of said car units being of a length approximately equal to that of a cargo trailer to be carried thereby and comprising a center sill extending substantially the entire length of the car unit, one mating member of said articulated connector fixed on one end of each car unit and a second of said mating members fixed to a second car unit, an end sill disposed transversely on each car unit and extending symmetrically beyond the width of said center sill, a pair of side bearing support members extending from respective sides of said center sill at a point spaced from said one end to respective ends of said end sill and extending longitudinally between car units, and a railway truck coupled to the other end of said center sill, said single railway truck assembly comprising a pair of side frames holding a pair of axles having wheels mounted thereon, a truck bolster disposed between and extending substantially parallel to said axles for supporting said articulated connector, a side bearing support member on said bolster on opposite sides of the longitudinal axis of said bolster, and side bearings disposed on each of the side bearing support members, each side bearing on the same side of said longitudinal axis supporting said pair of side bearing support members of one of said interconnected car units, said car unit having only a short platform on each side of said center sill at one end adjacent and offset from the wheels of said truck assembly to support wheels of a cargo trailer at a height approximately the same as that of said truck assembly wheels, and a trailer hitch mounted on said center sill substantially over the articulated connector whereby the weight of the cargo trailer is supported by opposite ends of the car unit adjacent the railway trucks and the front of a trailer may extend beyond said trailer hitch to a position to minimize the gap with the rear of a trailer on a preceding car unit.
A railway car comprising at least two railway car units mounted on a single railway truck assembly which spans the gap between car units, said car units being connected together by an articulated connector having mating members and mounted on said single truck assembly, each said car unit comprising a center sill extending substantially the entire length of said car unit, each said center sill also comprising a pair of platforms, one connected to each side of said center sill located substantially lower than the top of said center sill and positioned between railway truck assemblies at a height below the height of the railway truck wheels, and a trailer hitch disposed at a location on said center sill of each unit of said car assembly near the centerline of the said articulated connector, one mating member of said articulated connector fixed on one end of one of said car units and a second mating member disposed fixed to a second of said car unit ends, an end sill disposed transversely on each of the car units and extending symmetrically of said center sill, a pair of side bearing support members extending from respective sides of said center sill at a point parallel with said center sill and dimensionally compatible with said truck assembly side bearing supports on a truck bolster, each pair of side bearing support members on each car unit of said railway car assembly being directly opposed in a horizontal and vertical plane of alignment, said single railway truck assembly comprising a pair of side frames holding a pair of axles having wheels mounted thereon, a truck bolster disposed between and extending longitudinally substantially parallel to said axles for supporting said articulated connector, a side bearing support disposed on said bolster, and two pairs of side bearings with one pair disposed on each said bearing support on opposite sides of the longitudinal axis of said bolster, each pair of side bearings on the same side of said longitudinal axis supporting said pair of side bearing support members of one of said interconnected units, said car units each having only short platforms on each side of the center sill as the deck of the said unit.
