Abstract
A railroad car for carrying containers has a car body mounted on trucks. The car body includes two side sills connected to two end frames. The side sills and end frames define an open well which is adapted for receiving a container. The floor of the well is defined by a container support frame assembly which is hung from the side sills by four hanger straps. The container support frame assembly includes two transverse support beams. The hanger straps are pivotally connected by transverse pins to the side sills and the transverse support beams such that the hanger straps are stressed primarily in tension only and they transfer tensile loads but not bending loads to the side sills.

A railroad car for carrying containers, comprising:
- a car body mounted on first and second trucks, the car body comprising first and second side sills each connected at their ends to end frame assemblies, the side sills and end frame assemblies defining a well adapted for receiving a container therein;
- at least two pairs of elongated hanger straps, each strap having upper and lower ends, the upper ends being connected to the side sills with the straps of each pair being aligned on opposite sills;
- at least one container support frame assembly defining a floor of the well and including at least two transverse support beams which are connected near their ends to the lower ends of a pair of hanger straps, the support beams including mounting means for securing a container on the support frame assembly.
A railroad car for carrying containers, comprising:
- first and second side sills each connected to first and second trucks at the ends of the sills;
- a plurality of hanger straps, each strap having upper and lower ends, the upper ends being connected to the side sills;
- a container support frame assembly including means for mounting a container on the support frame assembly, the frame assembly being connected to the lower ends of the hanger straps such that the hanger straps are stressed substantially in tension only and the connection of the hanger straps to the side sills being such that the hanger straps transfer tensile loads but not bending loads to the side sills.
