AAR Pushback Coupler

For Regional, Intercity, High-Speed Trains and Railcars
  • Dellner AAR pushback coupler

The AAR pushback coupler, like Knuckle or Tightlock couplers, is based on the design of the Janney Coupler. Its name is derived from the Association of American Railroads (AAR). This type of coupler is particularly common in the USA.

The Dellner AAR pushback coupler is available for regional, intercity, high-speed trains and railcars. It complies with the American Public Transportation Association’s (APTA) PR-CS-RP-019-12 Rail Transit Standard. It has an anti-rotation joint, and the design of the coupler ensures that in the event of a collision, the end frames are brought together in a manner that minimises vertical and lateral movement between the coupled cars and the impacting cars.

The AAR pushback coupler is rigorously tested both statically and dynamically and equipped with a mechanical AAR Knuckle coupler head. The coupler has a rubber draft gear for regenerative energy absorption, the non-regenerative absorption is controlled via a deformation tube, whose force and stroke levels can be adjusted to meet the car builder’s crash energy management requirements.
