Title
(EN) RAILROAD RENEWAL METHOD AND DEVICE FOR IMPLEMENTING SAID METHOD
(FR) PROCEDE DE RENOUVELLEMENT DE VOIES FERREES ET DISPOSITIF POUR SA MISE EN OEUVRE
Abstract
(EN)
The invention relates to a railroad renewal method and device, the method including, in particular: the removal of the old rail (A), the installation of the new rail (B) and the primary adjustment of the temperature of said new rail to a set value (T1) at a point (C) located upstream of and close to the attachment area (F) on a crosstie (H). The thermodynamic behavior of the intermediate section (R) of the new rail (B) located between the primary temperature adjustment point (C) and the attachment area (F) is controlled by means of a device, provided with a control and management system (G), such that the temperature of the new rail (B) is uniform, in the cross-section thereof, at a set value (Tf) on the attachment point (F).

(FR)
Procédé et dispositif de renouvellement de voies ferrées, le procédé comprenant, notamment, la dépose de l'ancien rail (A), la pose du nouveau rail (B) et le réglage primaire de la température de ce nouveau rail à une valeur de consigne (T1) en un point (C) situé en amont et à proximité de sa zone de fixation (F) sur une traverse (H). Par moyens d'un dispositif pourvu avec un système de contrôle et de gestion (G) on contrôle le comportement thermodynamique du tronçon intercalaire (R) du nouveau rail (B) situé entre le point (C) de réglage primaire de sa température et la zone de fixation (F) de telle sorte que la température du nouveau rail (B) soit homogène dans sa section à une valeur consignée (Tf) au point de fixation (F).
