This new facility, which will host the High-Speed Trains (TAGV) of the new railway operator Velvet starting in 2028, will be the first private maintenance site in France. Strategically located on the Atlantic coast, it will play a key role in the performance, reliability, and safety of rolling stock operating on the Atlantic high-speed line.
As part of this system integration project, Colas Rail is in charge of:
. 3.5 km of railway track with the installation of 6,200 sleepers and 30 switches and crossings
. Signalling and low/high voltage systems (CFA/CFO), including 30 switch motors, 70 signals, and a 25 kV / 1.5 kV traction power supply carried out in partnership with our signalling subsidiary SafeRail
. Catenary composed of 30 flexible gantries, 19 section insulators, 3 km of feeder cable installation, 170 catenary poles, and 600 m of retractable catenary
. Civil engineering and utilities (VRD) with 120,000 m³ of earthworks, 8 km of drainage systems, and 45,000 t of graded aggregates
. A maintenance workshop with complete installations: tandem underfloor wheel lathe, train washing machine, three drainage lines for trains, 28 mobile jacks, ultrasonic test bench
"This project demonstrates Colas Rail’s ability to mobilize its full range of expertise – track, signalling, catenary, civil works, and specialized equipment – in synergy with its partners, to deliver a sustainable, high-performance, and safe facility", explains Alexis d’Audiffret, Project Director at Colas Rail.
