Alstom will supply an on-board automatic train control system for Line 8 of the Paris Metro as part of a wider modernisation programme led by RATP Group on behalf of Île-de-France Mobilités.

The contract forms part of the OCTYS 2030 programme, which aims to introduce upgraded signalling and automated control technologies across parts of the metro network. The programme is intended to support the introduction of the MF19 trains, which are scheduled to enter service on Line 8 by 2029.

Under the agreement, Alstom will supply its I-CBTC on-board automatic control system together with a radio communications system that enables data exchange between trains and trackside equipment. The system will operate at Grade of Automation 2 (GoA2), meaning trains will be automatically controlled while still operated by a driver.

With I-CBTC, we are providing a reliable, state-of-the-art automatic control solution designed and integrated by our teams in France. We are delighted to once again contribute to the modernisation and improvement of the Paris metro performance alongside RATP and Île-de-France Mobilités.

The I-CBTC technology is a communication-based train control system designed for metro networks. It enables trains to operate with shorter but controlled spacing and provides real-time supervision of train movements. This can support more regular service operation and improved reliability.

The technology already operates on several parts of the Paris Metro network. Lines 5, 6, 9, 10 and 11 have been equipped with the OCTYS on-board solution developed by Alstom. More than 200 trains currently operate with the system, which the company said supports services used by over 350 million passengers each year.

The contract for Line 8 covers development, validation, installation and commissioning of both the on-board control equipment and the radio communication system. Alstom will also coordinate the overall implementation of the automatic driving system.

Work on the project will involve several of the company’s sites in France. The Aix-en-Provence facility will lead project management, development and systems engineering. The Saint-Ouen site will carry out studies for radio deployment as well as installation and testing on the network. Electronic equipment and reliability engineering will be provided by the company’s facility in Villeurbanne.
