A coupler for a railway vehicle includes a coupler anchor and a coupler centering device having a pair of arm sub-assemblies. Each arm subassembly has an upper centering arm connected to a lower centering arm via a torsion bar extending through the coupler anchor. The lower centering arms are connected by a cross link such that movement of one of the upper centering arms causes a corresponding movement of both of the lower centering arms. Each upper centering arm engages a roller that rolls along a curved surface of the centering arm when the coupler is rotated horizontally toward the upper centering arm. A centering stop element prevents the movement of the opposing upper centering arm to generate a restoring force in the torsion bars that facilitates horizontal movement of the coupler. The coupler centering device may be disengaged from an active centering position to facilitate servicing of the coupler.

A coupler for a railway car including a coupler anchor, a coupler mechanism pivotable relative to the coupler anchor from an on-center position to an off-center position in a substantially horizontal plane, and a coupler positioning device for pivoting the coupler mechanism relative to the coupler anchor. The coupler positioning device includes a controller adapted for receiving signal information from a bogie relating to an angular position of the bogie relative to a body of the railway car, and at least one pneumatic cylinder for pivoting the coupler mechanism. The controller controls the operation of the at least one pneumatic cylinder in response to the signal information received from the bogie.
