Abstract
A railroad renewal method includes, in particular: the removal of the old rail, the installation of the new rail and the primary adjustment of the temperature of the new rail to a set value at a point located upstream of and close to the attachment area on a crosstie. The thermodynamic behavior of the intermediate section of the new rail located between the primary temperature adjustment point and the attachment area is controlled by way of a device, provided with a control and management system, such that the temperature of the new rail is uniform, in the cross-section thereof, at a set value on the attachment point.
