Retarder

In rail transport, a retarder is a device installed in a classification yard used to reduce the speed of freight cars as they are sorted into trains. Each retarder consists of a series of stationary brakes surrounding a short section of each rail on the track that grip and slow the cars\' wheels through friction as they roll through them.
