Abstract
A universal retarder system for slowing a railcar on rails. The system includes a lever arm configured to be pivotable within a vertical plane, where the lever arm is configured to support a brake shoe. An engagement device is coupled to the lever arm and configured to pivot the brake shoe towards one of the rails. A disengagement device is coupled to the lever arm and configured to pivot the brake shoe away from the one of the rails. The lever arm, engagement device, and disengagement device are each positioned between the rails. Pivoting the brake shoe towards the one of the rails is configured to force the brake shoe into engagement with the railcar to slow the railcar.
