Beware of works.
Like every summer, the RATP and the SNCF are taking advantage of the drop in attendance in the capital region to carry out major modernization operations.
Rails, ballast, switches… nearly 4.8 billion euros will be invested in 2022 to, one day, improve passenger comfort and train regularity.
And who says work necessarily means inconvenience for summer users.
From this Friday, July 15, we are moving up a gear.
Several lines will be interrupted, sometimes for several weeks, to make way for thousands of workers and technicians.
Here are the main disruptions to take into account in your travels, starting this weekend.
