Abstract
A work train lays a rail of a railway track. The work train has a heating device with a heating zone, gas burners, and a radiant body interposed between the gas burners and the heating zone. The radiant body has openings that open into the heating zone. The work train is moved in a laying direction, so that at each moment a portion of the rail to be fixed passes through the heating zone. Heat is supplied to the rail to be fixed through the heating zone by feeding the gas burner so that no flame emerges from the openings in the heating zone and that at least 75% of the heat supplied to the rail is transmitted by radiation from the radiant body. Then the rail is fixed after the heat has been applied to a tie of the railway track behind the heating zone in the laying direction.
