Abstract (en)

[origin: CA3060848A1] In order to lay a rail (12) of a railway line using a work train (4) comprising at least one heating device (32) having at least one heating zone (28), one or more gas burners (42), and one or more radiating bodies (44) arranged between the gas burner or burners (42) and the heating zone (28), the radiant body or bodies (44) being perforated by openings (46) opening into the heating zone (28), the work train (4) is moved in a laying direction (100), so that at each instant a portion of the rail to be fixed (12) crosses the heating zone (28), the heat is applied to the portion of the rail to be fixed (28) crossing the heating zone (28) using the heating device (32) by supplying the gas burner or burners (42) such that no flame emerges from the openings (46) in the heating zone (28) and such that at least 75%, and preferably at least 80%, and preferably at least 85% of the heat applied to the portion of the rail (12) is transmitted by radiation from the radiating body or bodies (44); then the portion of the rail (12) is fixed after applying the heat on a sleeper (10) of the railway line situated behind the heating zone (28) in the laying direction (100).
