Open the CIPO recordAbstract From the Canadian patent
A method of improving the characteristics of a railway track, and apparatus for use therein involves, the generation of a high energy beam capable of being aimed and focused, and directing the beam against the track at at least one position on the track section where improvement is to take place. The beam is progressively moved along the track at a speed which allows the irradiated part of the track to be heated to an elevated temperature, whereby the improvement occurs upon cooling of the track from the elevated temperature.
