MUNICH, Germany, Sep 4, 2025 – Siemens Mobility has signed a contract with RATP to deliver the new train operation automation system for Paris Metro Line 13. The project will use Siemens Mobility‘s CBTC GoA4 technology to enable driverless operations, expand transport capacity, improve service reliability, and optimize energy usage. The new contract covers 66 trains and a control center, and an optional maintenance agreement of up to 30 years. The project builds on earlier deployments of driverless systems on Paris Metro Lines 1, 4, and 14, and will enable driverless operation on Line 13 by 2032.
“Our selection for the Line 13 automation project reflects RATP´s continued trust in our expertise. We are proud to support RATP in their ambition to deliver decarbonized, high-performance, and comfortable transport solutions that boost rail attractiveness and contribute to the fight against climate change. Together, we’re shaping the future of mobility in Paris,” said Marc Ludwig, CEO of Siemens Mobility Rail Infrastructure. “We’ve had the privilege of contributing to several successful projects in Paris over the years. With Line 14, we achieved a world first by upgrading an existing driverless system to our advanced CBTC GoA4 technology while simultaneously extending automation to new sections of the line. This breakthrough enables Line 14 to serve up to one million passengers daily at 85-second intervals. With Line 13, we’re building on this expertise, upgrading one of Paris busiest lines to operate fully automatically.”
Line 13 Modernization: Full Automation Project Set to Transform Paris Metro Operations
Modernization of Line 13 will begin in 2027 with new rolling stock, followed by installation of an automation system. The current GoA2 system, where drivers control doors and safety while acceleration and braking are automated, will be upgraded to a GoA4 system for full automation. The project covers equipping the new train fleet, renovating the operations control center (OCC), staff training, and an optional maintenance agreement.
Siemens Mobility’s CBTC GoA4 automation system for Line 13 will improve passenger service. It will increase transport capacity by reducing train intervals, adjust frequency based on passenger demand, enhance service reliability, and lower energy consumption. The system will also provide real-time passenger information on trains.
This project will be executed from Siemens Mobility’s global center of excellence for rail automation and cybersecurity in Châtillon, near Paris, where a team of over 500 engineers specializes in system design and development.
Line 13: A Critical North-South Connection in Paris Metro Network
Line 13 spans 24 kilometers and 32 stations, linking Châtillon-Montrouge in the southwest to Saint-Denis-Université and Les Courtilles in the north of Paris. Serving transport hubs like Saint-Lazare and Montparnasse-Bienvenüe, it carries more than 550,000 passengers daily, making it one of Paris’s heavily used lines and a prime candidate for automation.
