The benchmark in high-capacity commuter trains

RATP Dev draws on its metropolitan rail expertise - forged on lines with some of Europe’s highest passenger numbers - to design, operate, and modernize commuter trains rooted in the areas they serve.

Commuter trains provide large-scale connections throughout major cities. They link residential neighborhoods to employment hubs, shorten journeys, and offer a credible alternative to the private car for long trips. By broadening accessibility, they make the city more inclusive, more productive, and more equitably balanced.

The Paris region includes lines with passenger numbers among the highest in the world, amid an extremely dense environment with a multitude of branches and players. Management of very high passenger numbers, precise sequencing, operation of a vast spectrum of equipment, modernization of systems in continuous operation... All this has honed a unique mastery of complex urban rail systems.


Today, RATP Dev puts that expertise at the service of major cities in France and around the world.

Creation of entirely new lines, modernization of existing networks, operation of links to airports and commuter trains… Our teams assist organizing authorities at every stage of the project life cycle, always adhering to the highest standards of operational efficiency, reliability, and service quality for the passengers.
