Artelia supports rail transport stakeholders in the creation, development, modernization, and renewal of infrastructure. Leveraging its multidisciplinary engineering expertise, the Group is involved across the full spectrum of rail projects—lines, stations, intermodal hubs, and engineering structures—providing consultancy, project management assistance, and design services to deliver more efficient, reliable, and sustainable networks.

Among its flagship projects is the modernization of the Périgueux–Brive line, for which Artelia is delivering full design services from 2023 to 2029. With a strong focus on sustainable renewal, the Group also contributes to programs aimed at upgrading regional secondary lines and existing infrastructure, integrating key considerations such as safety, operations, environmental performance, and intermodality. Artelia is also involved in the development of strategic rail facilities, including the design of the Montigny-lès-Metz maintenance and stabling site (France), which features four tracks equipped with retractable catenary systems, stabling yards, EALE systems, overhead lines, signaling, and the PIVOS system. In addition, Artelia is responsible for execution design of all railway systems for Eiffage on the Villeneuve-Saint-Georges technicentre project (France). Artelia’s expertise is also deployed on major international projects, notably the Kenitra–Marrakech high-speed line (Morocco), where the Group is delivering integrated design services covering track, catenary, systems, and construction logistics (2024–2028). Finally, in 2025, Artelia was awarded a Project Management contract for the preparation of studies for the future Hanoi–Ho Chi Minh City high-speed line (Vietnam), as part of the EVRC consortium—demonstrating its commitment to major rail infrastructure and sustainable mobility.

Artelia supports local authorities in the studies, design, and delivery of metro, tramway, and Bus Rapid Transit (BRT) projects. Drawing on its expertise in transport engineering and urban planning, the Group develops high-performance infrastructure that is fully integrated into the urban environment and contributes to sustainable mobility (structures, systems, passenger buildings, stations, and intermodal facilities). Digital tools, BIM, and asset management approaches are leveraged to optimize the lifecycle of infrastructure, ensuring performance while adapting to the evolving needs of local communities. Artelia’s teams also carry out audits of existing infrastructure and develop multi-year asset management plans.

Artelia has strong expertise in the design and support of dedicated-lane urban transport projects, both in France and internationally. In France, the Group has contributed to the Montpellier tramway (Line T3), a major project for the metropolitan area that supports urban regeneration and modal shift, as well as to the TZen BRT network in the Île-de-France region for Île-de-France Mobilités— a high-level service network designed to enhance the performance and attractiveness of suburban mobility. Internationally, Artelia has supported the flagship Cuenca tramway project (Ecuador), which integrates the challenges of sustainable mobility, urban and heritage integration, and adaptation to the local context—demonstrating the Group’s ability to deliver complex projects in diverse environments.

Artelia has full command of urban public transport infrastructure, from design through to operations. The Group supports major projects such as the Grand Paris Express, mobilizing expertise in civil engineering, systems, energy, signaling, safety, and interface management. Its strength lies in its ability to ensure the overall coherence of projects—anticipating challenges, continuously adapting, and bringing teams together around a shared objective: to design and deliver reliable, sustainable, and user-focused infrastructure.

As a coordinator and integrator, Artelia ensures strategic, technical, and operational alignment among all stakeholders, contributing to collective project success.

On behalf of the Société des Grands Projets, Artelia is involved in Lines 15, 16, and 17 in a project management assistance role, supporting the client in technical steering, design and construction supervision, interface management, and the control of costs, schedules, and risks. For Line 18, Artelia delivers full design services, taking responsibility for detailed technical design and construction supervision, with a focus on overall project performance and integration within its environment.
