This year’s engineering works are taking place in two stages and on two sections from 11 July to 30 August inclusive. To organize your journeys and don't forget the line’s closings, download our digital calendar designed for optimal readability on your mobile phone.
First, service on RER line A will first be suspended between Auber and Vincennes stations, from 11 July to 7 August. After this, the line will be closed between Auber and Nanterre—Université • Cergy • Poissy stations from 15 to 30 August.
In the meantime, you can continue to visit this dedicated website that will be regularly updated, and the line’s Twitter account.
Many pedagogical and informational tools will soon allow you to prepare this period of traffic interruption on the line.
