Abstract
There is disclosed a method and a gas actuated retarder system for railway cars to control the rolling speed of a railway car along a first and second running rails of a track section. The retarder system includes a plurality of steel ties positioned substantially parallel to each other and perpendicular to the first and second running rails of a track section. A plurality of gas bladder mounts are positions between the running rails of the gas actuated retarder system. Coupled to each of the gas bladder mounts are air bladders with one air bladder on a side of the centerline of the gas actuated retarder system. Inflating and deflating the gas bladder selectively controls the amount of speed reduction of the railcar.
