  • Patent number: 4306504
    Abstract: A stationary railroad rerailing apparatus for rerailing derailed cars while the train is moving, including V-shaped centering rails between the track rails, an inclined pad of a cushioning, penetrable material, such as asphalt-aggregate material, for raising the derailed car, rigid wedges outside the track rails for cooperating with the inclined pad to raise the derailed car wheels above the level of the track rails, and platform members outside the track rails for carrying the wheels of the derailed car above the level of the track rails until they are shifted by the centering rails over the track rails and into a rerailed position. The novel pad material allows the derailed car to be guided and replaced into proper position in a controlled manner.
