Abstract
A pocket-casting is provided for a railcar slackless coupler having a draft gear subassembly for preloading the coupler assembly in the buff and draft directions, which pocket-casting and cooperating positive stops in a center-sill of a railcar limit the longitudinal travel and consequent loading of the slackless coupler in both the buff and draft directions for transfer of the forces to the plate-reinforced center sill to ease the shock loading on the coupler assembly.
