Abstract
A method of repairing a defect in a damaged rail of a railroad track comprises positioning a rail profiling device on the rails of the railroad track proximate a defect; securing the rail profiling device to the railroad; adjusting its grinder according to a selected value of wheel cone angle to create a profiled running surface over a portion of the damaged rail; creating a median zone using the grinder to remove material from the damaged rail adjacent the defect at a depth corresponding to at least a maximum depth of the defect; creating an incline from the top of the rail and leading to the median zone and one incline leaving the median zone to the top of the rail by using the grinder to grinding material off the damaged rail.

A method of repairing a defect of a damaged rail of a railroad track having two rails, the method of repairing using a rail profiling device having a grinder, the method comprising:
- positioning the rail profiling device on the rails proximate the defect;
- securing the rail profiling device to the railroad;
- adjusting a grinder of the rail profiling device according to a selected value of wheel cone angle to create a profiled running surface over a portion of the damaged rail;
- creating a median zone, said creating the median zone comprising using the grinder of the rail profiling device to remove material from the damaged rail adjacent the defect at a depth corresponding to at least a maximum depth of the defect with respect to a top running surface of the damaged rail, said median zone extending substantially parallel to the top running surface of the rail;
- creating a first incline, said creating the first incline comprising using the grinder to grind the damaged rail starting from a first extremity of said median zone and gradually reaching the top running surface of the damaged rail over a first longitudinal distance ahead of said median zone;
- and
- creating a second incline, said creating the second incline comprising using the grinder to grind the damaged rail starting from a second extremity of the median zone and gradually reaching the top running surface of the damaged rail over a second longitudinal distance behind said median zone.
