OK OUR QUICK SUITES: WORK TRAINS CAPABLE OF RENEWING ALL THE COMPONENTS OF THE TRACK IN A LIMITED TIME. LARGE-SCALE PROJECTS The materials are transported from a work base on specialized trains which also include works machinery. The works are carried out thanks to an interruption of 7 to 9 hours of traffic. About 500 people work on the site, with some 2 km of specialized equipment, for a value that exceeds 100 million euros. THE STAGES OF A CONSTRUCTION SITE 01. THE SUBSTITUTION This is to detach the rails from the track. Then the old wooden or concrete sleepers are removed and replaced by concrete sleepers. The rails are gradually put in place, fixed on the sleepers and welded together. 02. DISRUPTION The tracks are raised and the old ballast is removed. The recoverable part is screened and placed back on the track, while the non-recoverable ballast is loaded into cars located at the front or rear of the rapid suite. 03. THE LIFTING the track must be leveled. This is a very precise operation since we work to the nearest millimeter. The ballast is dumped in sufficient quantity then the track is positioned (by a tamper) before the ballast is profiled (by a leveler). 04. THE LIBERATION Cette opération a lieu quelques jours après le relevage. Le rail est amené à une température comprise entre 20 et 32°C. Il s'agit de préparer le rail aux efforts de dilatation et de traction qu'il subit en permanence lors des variations de température. La circulation normale des trains est rétablie.
