... widely used application of the thermite welding process. The use of that process, as well as the electric flash butt welding process, has eliminated joint bars (mechanical fasteners) and greatly lessened track maintenance. Long sections of continuous welded rail (CWR) (typically, 440 m, or 1440 ft...
