Siemens Automates Paris Metro Line 13 with GoA4
Siemens awarded RATP contract for fully automated Paris Metro Line 13, utilizing CBTC GoA4 technology.

Introduction
Siemens Mobility has been awarded a contract by the Regie Autonome des Transports Parisiens (RATP) to fully automate Paris Metro Line 13 using its CBTC GoA4 technology. The project, announced on August 28, 2025, aims to enable driverless operations on one of the city’s busiest metro lines, with the modernization commencing in 2027.
Project Overview
The project aims to enhance Paris Metro Line 13 by enabling driverless operations, increasing transport capacity, and improving service reliability and energy efficiency. The decision to automate Line 13 was made by Île-de-France Mobilités in 2022.
Scope of Work
The contract includes an automation system, a new operations control center, and equipment for 66 trains. It also includes an optional maintenance agreement of up to 30 years. The scope of the project also encompasses the renovation of the Operations Control Centre and staff training. The modernization will commence with the rollout of new rolling stock in 2027, followed by the transition from the current GoA2 system to the fully automated GoA4 system. The project will be managed from Siemens Mobility’s global center of excellence for rail automation and cybersecurity in Châtillon, near Paris. Line 13 stretches 24km with 32 stations, serves key transport hubs Saint-Lazare and Montparnasse-Bienvenüe and carries over 550,000 passengers daily.
Technology and Benefits
Siemens Mobility’s CBTC GoA4 system promises to bring substantial performance improvements to Line 13, including the ability to adjust frequency dynamically in response to passenger demand. Real-time passenger information will also be provided onboard trains, enhancing the travel experience.
Additional Contracts
Siemens Mobility Norway has secured a contract to supply a signalling and train control system for the new Diakonhjemmet Station on the Oslo Metro network. This contract with Sporveien, Oslo’s public transport operator, demonstrates Siemens Mobility’s growing presence in the European rail automation sector.
Conclusion
Siemens Mobility is set to fully automate Paris Metro Line 13 with its CBTC GoA4 technology, with the project starting in 2027 and full automation expected by late 2032. The project involves an automation system, new control center, and equipment for 66 trains, enhancing capacity and efficiency. Siemens Mobility Norway has also secured a contract for the Oslo Metro network.
