Abstract
A slackless railcar coupler assembly, which is mountable in a railcar center sill, has a draft gear subassembly operable against a rear stop, and a slackfree coupler apparatus mounted in a coupler pocket forward of said draft gear subassembly, which subassembly and apparatus are connected to provide a dynamic load in both the buff and draft directions to avoid a mechanical, longitudinal stress load on the coupler assembly and railway car.
