What SafeRail does

SafeRail SAS is a French engineering services firm specialising in railway control-command and signalling (CCS) systems for guided transport, including high-speed lines (LGV), conventional rail, metros, RER networks, and tram-trains. Founded in 2003 and headquartered in Nantes, the company employs 101–250 staff across six French offices (Nantes, Les Ulis, Saint-Denis, Toulouse, Lille, Lyon) and operates as a wholly-owned subsidiary of Colas Group (Bouygues). SafeRail covers the full CCS project lifecycle — master planning, design studies, works, technical verifications (VT), testing, commissioning, FDMS (Reliability/Availability/Maintainability/Safety) studies, independent validation (V&V), and maintenance — under one roof, supplemented by the SAFERAIL Academy training centre and a proprietary digital field tool (OutilNomade).

The firm's core technology portfolio rests on CENELEC-compliant signalling expertise, OQA accreditation from the French Ministry of Transport for safety evaluation, SNCF Réseau qualification for MOE and travaux on the entire French National Railway Network, and ISO 9001 certification maintained since 2008. SafeRail participates in European standardisation bodies (Eulynx, RailTopoModel) and research clusters (IRT, Rail Open Lab), positioning it within the institutional ecosystem shaping next-generation ERTMS/ETCS and digital interlocking deployments. Its primary clients are French public infrastructure managers and operators — notably SNCF Réseau, RATP, and Société du Grand Paris — for whom it delivers flagship programmes including the LGV+ Paris–Lyon modernisation (consortium with Eiffage and Systra, awarded June 2020), the Grand Paris Express lines 15/16/17 (AMO Ingénierie Systèmes and AMO Essais, ~200 km of automated metro), the T13 tram-train (operational July 2022), and NExTEO RER E signalling advisory for Siemens.

Commercially, SafeRail operates as a B2B professional services firm with all revenue derived from public procurement contracts and long-term enterprise engagements. The GTM model is direct enterprise field sales to government infrastructure clients, with no published pricing and no reseller or distribution channel. Project delivery is executed either as prime contractor, as a consortium partner, or through the SRES joint venture with EST Signalisation for physical works. As a subsidiary of Colas Group, the company benefits from parental backing and access to broader infrastructure capabilities, but its own disclosed financial metrics are not public.

Core offering

SafeRail provides specialist engineering services across the full lifecycle of railway control-command and signalling (CCS) systems for guided transport — including high-speed lines (LGV), conventional rail, metro, RER and tram-train networks. Services encompass master planning, design studies (maîtrise d'œuvre conception), works, technical verification (VT), maintenance, testing, commissioning, FDMS (Reliability, Availability, Maintainability, Safety) studies, independent Validation & Verification (V&V), consulting and technical assistance. The company also operates the SAFERAIL Academy training centre and deploys the proprietary OutilNomade digital field tool.

Product overview

SafeRail is a French engineering services company specializing in railway control-command and signaling systems for urban guided transport and mainline railways. The company operates as a single integrated service offering rather than a platform with separate modules. Their core services encompass the complete project lifecycle: design engineering (maîtrise d'œuvre conception), works/VT/maintenance, testing/commissioning/FDMS studies, consulting/technical assistance/V&V, research/development/innovation, and design-implementation. SafeRail also offers specialized training through the SAFERAIL Academy and deploys proprietary field tools such as OutilNomade Saferail for digital data collection.
