Technical Specifications

The core of the modernisation effort is the deployment of advanced Communications-Based Train Control (CBTC) systems across multiple lines. The system, designated OCTYS-CBTC, enables higher train frequency and enhanced safety protocols. This technology underpins the full automation (GoA4) of key lines, such as Line 1, which has operated with driverless trains since 2012. Siemens has been a key supplier for the driverless operation equipment and automatic train control (ATC) systems. Ongoing extensions, such as the Line 14 southern extension to Orly Airport, involve complex tunnel boring machine (TBM) operations, with contractors like Eiffage managing significant civil engineering works. The rolling stock is also being systematically upgraded, with manufacturers like Alstom supplying new-generation trains designed for higher capacity and improved passenger experience.

Key Takeaways

  • Technological Upgrades Drive Efficiency: The implementation of CBTC signalling and full automation is central to increasing network capacity and operational reliability without requiring extensive new physical infrastructure.
  • Strategic Expansion for Regional Integration: Extensions to lines 1, 4, 11, and 14 are designed to connect underserved suburbs and key transport hubs like Orly Airport, fostering greater economic and social integration across the Île-de-France region.
  • Collaborative Public-Private Execution: The project’s success relies on a complex partnership between public authorities (RATP, Île-de-France Mobilités) and a consortium of specialised private engineering, construction, and technology firms.

Frequently Asked Questions (FAQ)

When will the Paris Metro extensions be complete?

The Paris Metro expansion is a multi-phase programme with different completion dates for each project. For example, major extensions on Line 14 are largely operational, with final links completing in the near term, while the proposed extension of Line 1 is targeted for completion by 2030. Other line extensions are progressing in stages throughout the mid-to-late 2020s.

Who is building the new Paris Metro lines?

The construction and modernisation are a collaborative effort. RATP operates the system and oversees the projects in coordination with the Île-de-France Mobilités transport authority. Key construction and engineering work is performed by companies such as Eiffage Public Works and Webuild. Critical technology, including signalling and rolling stock, is provided by industry leaders like Siemens, Alstom, and Hitachi Rail.
