Alstom deploys ATO on Paris RER Line A [free access]

May 10, 2017

Alstom has deployed an automatic train operation (ATO) technology on the Nanterr to Préfecture and Val-de-Fontenay to Fontenay-sous-Bois sections of the Paris RER Line A under a EUR20 million contract awarded by Régie Autonome des Transports Parisiens (RATP) and Syndicat des transports d'Île-de-France (STIF) in January 2015.


The scope of the contract included detailed studies, development of a prototype, onboard equipment, testing and provision of project support services. So far, onboard equipment has been deployed on a double-deck MI09 electrical multiple unit (EMU), and by November 2018, Alstom will install ATO onboard equipment on the line’s entire fleet of 183 MI2N and MI09 trains.


The ATO solution developed by Alstom overlays the existing Sacem ATC system, which was introduced in 1989, and upgrades the line to Grade of Automation (GoA) 2, with the driver continuing to start the train and operate the doors.


RATP is also considering the deployment of ATO on RER Line B, and is planning to introduce an interchangeable and interoperable communications-based train control (CBTC) solution on the common section of Lines B and D.
