Abstract
A railway flat car having a depressed load carrying portion to reduce the center of gravity of the car. The flat car includes a side sill assembly having upper end section having floor portions and a lower intermediate section for supporting the depressed load carrying portion. The depressed portion is formed with an overall width less than the upper floor portions. The car is provided with an intermediate longitudinal center sill that merges with end draft sills having a larger width than the center sill.
Claims24
A flat car supported on end truck assemblies comprising
- a body formed by a longitudinally extending center sill, a draft sill attached to each end of said center sill, and a pair of bulkheads mounted at each end,
- side sill means disposed on opposite sides of said center sill on said body,
- a vertical center beam assembly extending upward from said center sill,
- said vertical center beam assembly including an upper center sill extending parallel above said center sill between said bulkheads, said upper center sill being supported by a plurality of columns carried by at least said center sill, and
- floor means being arranged between said opposite side sill means, said floor means having end floor sections lying in a first generally horizontal plane and an intermediate depressed floor section disposed in a second generally horizontal plane lying below said first horizontal plane,
- said side sill means includes a pair of side sill assemblies disposed on opposite sides of said center sill, each of said side sill assemblies includes a pair of upper end sections extending along an upper axis for respectively supporting said end floor sections and an intermediate section extending along a lower axis disposed below said first axis for supporting said intermediate depressed floor section.
