Made-to-measure and turnkey projects
Dorsalys teams mobilise the skills and resources of the Eiffage group to ensure the integration of systems and the turnkey execution of your major rail and urban projects. We support you from the design to the commissioning of your equipment and manage its maintenance.
Rail transport infrastructure
Dorsalys teams work to meet the requirements of local authorities and operators as efficiently as possible, in order to bring territories closer together and connect them, by deploying reliable, sustainable and secure rail infrastructures. We work on the design, installation, integration and maintenance of High Speed Lines (HSLs), regional lines, stations and stops, rail tunnels and operation/maintenance centres.
Our teams are able to support you in the following areas of expertise :
- Telecommunications (RMS, video surveillance, rail telephony, etc.) ;
- Low voltage distribution ;
- Electric traction (25 kV, 1,500 V, etc.) ;
- Rail signalling ;
- Remote monitoring (CTM)/supervision/control centres (Scada) ;
- Creation of cable and fibre-optic networks ;
- GSM-R.
Urban transport infrastructures
Our experts design, install and incorporate comprehensive urban transport offers (tramway, metro, HSLB (high service level buses)) and provide you with their expertise in the following areas :
- Low voltage infrastructures: video, low voltage in stations, intercoms, RMS, CTM, fire, intercoms, lighting, etc.
- HV/LV distribution ;
- Electric traction ;
- Rail signalling ;
- Traffic lights ;
- Platform doors/access systems and gates ;
- Electric bus charging infrastructure ;
- Radio telecommunication ;
- Boxes, switchboards and safety frames.
Buildings, stations and stops
For your buildings, stations and stops, we bring you our expertise in electrical and climate engineering and work on :
- Access contro ;
- Video surveillance ;
- Passenger information, sound system, floor signage ;
- Telephony, intercoms ;
- Air monitoring and detection of nuclear, radiological, bacteriological, chemical and explosion risks ;
- Fire detection/extinguishing ;
- Lighting and LV distribution ;
- Ventilation, smoke extraction, air conditioning ;
- Drainage, depletion, ejection ;
- Access point mechanisms and closures ;
- Boxes, switchboards and safety frames.
All our projects in France and abroad are carried out with due respect for the safety of people and property.
A concentrated expertise for an exceptionally large project
Eiffage Énergie Systèmes’ experts produced all the rail equipment (excluding railway tracks) for the HSL linking Le Mans to Rennes, which was commissioned in 2017. Dorsalys teams were therefore mobilised in the context of the largest (turnkey) contract ever awarded to the Eiffage group. It is also the largest operation carried out to date by Eiffage Énergie Systèmes.
More than 500 employees and partners were involved in this project for the installation of substations, lines, optical fibre, mechanised trenches, cable burial, lighting, rail signalling, etc.
This range of expertise enabled the successful commissioning of trains running from Le Mans to Rennes at 320 km/h in complete safety.
