Abstract: A rerailing device for rerailing a wheel of a railcar or the like which has been derailed due to a spread rail comprising an L-shaped metal bar member including a vertically disposed bar portion and a horizontally disposed bar portion which extends horizontally from the upper end of the vertically disposed bar portion. A vertically disposed flat metal plate is secured to one side of the vertically disposed bar portion and extends horizontally therefrom beneath one side of the horizontally disposed bar portion. The rerailer may be of the left-hand or right-hand type to enable the rerailer to be mounted at either end of a rail joint bar so that the derailed wheel may be brought into engagement therewith and moved upwardly thereonto to retail the derailed wheel.
