ABSTRACT:
A replacement roof panel for repairing damaged railway car roofs in the field. The damaged portion is cut away leaving an opening in the roof. The repair panel is fabricated to the desired width and has reinforcing end portions that form laterally extending stiffening members. The end portions are shaped to provide slots along the lateral edges of the repair panel for receiving the edges of the existing roof sheet. The repair sheet is then welded along its edges to the existing roof sheet and to the side plates of the car.
