Network modernisation

All you need to know about summer works

This summer, we will continue working on upgrading the public transport network to improve your journeys in the Île-de-France region. RATP, SNCF and Île-de-France Mobilités inform you so you can best plan your journeys.

Works are taking place everywhere during the summer because they benefit everyone.

Improving journeys for 12 million users in the Île-de-France region requires exceptional means. 
Summer works are reaching again an important scale this year, proportionate to our ambition to profoundly transform your public transport. This undertaking has already been ongoing for several years.
Summer works to reduce inconveniences during the rest of the year

We are aware that the works may disturb your daily activities. However, as passenger levels on the lines are 30% lower on average in July and August, we choose to group closures over this period as much as possible.
