Abstract
A railway car adapted to convey cylindrical objects such as coils includes a plurality of fixed trough members and sections of shiftable inclined trough assemblies disposed atop a support deck. By selectively laterally displacing the shiftable trough assemblies the car is alternately configured to provide single/triple or double troughs, or a combination thereof, in order to achieve maximum lading capacity in any one car regardless of the diameters of the coils. Positioning elements on each shiftable trough assembly alternately mate with a fixed trough member or separate positioning elements on the support deck to specifically define the various trough modes. A lock assembly is operable to engage a retainer element carried by each shiftable trough assembly when located in either mode.
