The Paris metro network is continuing its modernization and automation process. Line 8 will be equipped with the CBTC (Communication-Based Train Control) train control system, designed to improve the regularity and reliability of service.
Alstom will supply the on-board automatic train control system for line 8, operated by RATP on behalf of the regional transport authority Île-de-France Mobilités.
The contract is part of the OCTYS 2030 program, which is modernizing the Paris metro network by introducing automatic train control systems to improve the regularity and reliability of services.
The modernization is being carried out without any major impact on traffic and will enable the operation of future MF19 trains, which are due to enter service on line 8 by 2029.
CBTC system to increase capacity
The project includes two main components: The I-CBTC (Communication-Based Train Control) solution reduces the distance between trains and enables real-time traffic monitoring, helping to increase the regularity and capacity of the line.
- the automatic train control system installed on board (GoA2 – automation with driver);
- the radio system for communication between the train and the infrastructure.
“With I-CBTC, we offer a modern and reliable automatic train control solution, developed and integrated by our teams in France. We are delighted to once again contribute to the modernization of the Paris metro alongside RATP and Île-de-France Mobilités,” said Frédéric Wiscart, Alstom’s President for France, Belgium, and Luxembourg.
The system is already in use on several lines
The OCTYS system developed by Alstom is already installed on lines 5, 6, 9, 10, and 11 of the Paris metro.
In total, more than 200 metro trains use I-CBTC technology, carrying approximately 350 million passengers annually.
The system will be developed at three Alstom centers in France
The project will be carried out by three Alstom units in France: Alstom has over 30 years of experience in CBTC technology, with systems installed on over 190 metro lines in 32 countries.
Aix-en-Provence – project management and system development;
Saint-Ouen – studies, installation, and testing of the radio system;
Villeurbanne – supply of electronic equipment and reliability activities.
