A simple approach to rail head repairs

Rail defects manifest themselves in various ways and various stages during the life of a rail, and they can be isolated or can affect a long rail length; isolated defects can be tackled in isolation. Aluminothermic welding offers a way to repair isolated rail surface flat defects, while avoiding the need to insert short plug sections and maintaining the integrity of the rail. The Thermit Head Repair (THR) process is a build up welding method based on the Thermit technology used for joining rails, and although the technology was originally developed about 50 years ago, it is time to revisit the technique, which this article does.
