Systra and Arcadis Secure Toulouse Metro Line 3 Contract: A Case Study in Systems Integration
This article examines the significant contract awarded to Systra and Arcadis for the systems project management assistance (PMA) of Toulouse’s third metro line. The project, a testament to France’s continued investment in its public transportation infrastructure, showcases the complexities of modern automated metro system design, implementation, and integration. The scope encompasses far more than just track laying and train procurement; it includes the intricate orchestration of numerous systems, ranging from automated train control (ATC) and centralized traffic management (CTM) to the design of stations and maintenance facilities. This analysis will delve into the key aspects of the project, highlighting the roles of Systra and Arcadis, the technical challenges involved, and the broader implications for urban mobility and infrastructure development in France and beyond. The success of this project serves as a benchmark for future automated metro implementations globally, demonstrating both the technological prowess and the logistical coordination required for such large-scale undertakings.
Project Scope and System Integration
The contract awarded to the Systra-Arcadis consortium covers the complete systems definition for Toulouse Metro Line 3, a 27km line with 20 stations anticipated to transport over 200,000 passengers daily. This necessitates the meticulous integration of diverse systems, including:
- Rolling Stock: The selection and integration of appropriate automated rolling stock are crucial, requiring consideration of capacity, passenger comfort, and energy efficiency. The choice between fully automated driverless trains and those with driver backup must be carefully considered.
- Automated and Non-Automated Control Systems: Line 3’s systems will likely incorporate a mix of automated and non-automated control elements, demanding a robust and seamlessly integrated control system architecture.
- Centralized Control Systems (CCS): A CCS is the central nervous system of the metro, monitoring and managing all aspects of the system in real-time. This demands high reliability and redundancy to ensure continuous and safe operation.
- Track, Power, and Maintenance Equipment: The design and integration of track infrastructure, power supply systems, and maintenance equipment require careful coordination to ensure smooth operation and easy maintainability.
- Station Design and Integration: The design of the 20 stations must be carefully integrated with the overall system, considering passenger flow, accessibility, safety, and aesthetics.

The combined expertise of Systra and Arcadis creates a powerful consortium capable of handling the technological, logistical and managerial aspects of the project.
Broader Implications and Future Outlook
The successful implementation of Toulouse Metro Line 3 will significantly enhance connectivity within the Greater Toulouse region, improving accessibility to employment centers, the airport, and the main railway station. The project serves as a model for future urban transport development, showcasing the potential of automated metro systems to provide efficient, reliable, and sustainable public transportation. The line’s integration with existing transport networks—metro Lines A and B, tram lines, and bus lines—demonstrates a commitment to integrated transport planning and a move away from isolated transport solutions. The project’s success hinges on effective collaboration between the various stakeholders, including the client (Tisséo Collectivités and Tisséo Ingénierie), contractors, and regulatory bodies. Furthermore, the project’s sustainability considerations, such as energy efficiency and environmental impact mitigation, are vital aspects for its long-term viability and contribution to a greener urban environment. The experience gained from this project will inform future metro developments in France and beyond, driving innovation in automated metro technology and project management practices.
