Abstract

A system or method of repairing railroad rails which includes a head, upright and base sections. The method includes at least the following steps: identifying and locating a defect in the rail, removing the defect by removing material from the rail surrounding the defect in at least the head section so as to form a void and a rail void interface while maintaining continuity of the rail, filling the void with molten metal and causing the molten metal and the rail void interface to bond. The molten metal may be produced by gas shielded are welding. The carbon content of the molten metal is similar to that of the rail.
