Abstract (en)
A method of in situ repairing of a defect (15) in a rail (10) which comprises removing a piece of rail head (14) from the upper face of the rail head so that the rail web (13) and the rail foot (12), and optionally the lower part of the rail head (14) remain unaffected, so that in the rail head a recess, preferably a hole (20) is formed, whrein the recess debouches at its upper face, and teh method further comprises the filling of the recess (20) with a preformed, shape-retaining, preferably closely fitting, steel plug (21), the shape of the recess (20) and of the plug (21) being congruent in order to restore the original geometry of the rail.
