In a method of efficiently removing a great number of damaged rail sections, after a first separating cut, both rail ends are gripped by means of a rail pulling device (20) connecting the rail ends to one another, and are pulled towards one another. The pulling force required for the pulling-together as well an actual rail temperature are registered for calculation of that length of a replacement rail (14) which is required for producing a desired rail tension. A second separating cut is carried out - with corresponding path measurement - spaced at a distance from the first separating cut as calculated on the basis of the selected length of the replacement rail (14).

Dans une méthode d'enlèvement efficace d'un grand nombre de sections de rails endommagés, après une première coupure de séparation, les deux extrémités de rail sont saisies au moyen d'un dispositif de traction de rail (20) reliant ensemble les extrémités, et sont tirées l'une vers l'autre. La force de traction requise et la température réelle de rail sont enregistrées pour calculer la longueur d'un rail de remplacement (14) qui est nécessaire pour la production d'une tension de rail. Une deuxième coupure de séparation est effectuée, avec une mesure de trajet correspondante, à une certaine distance de la première coupure de séparation, calculée selon la longueur sélectionnée du rail de remplacement (14).
