Taking advantage of the average third of passengers who desert their lines during the summer period, Île-de-France Mobilités (IDFM), the organizing authority for public transport in the Paris region, takes advantage of the months of July and August each year to carry out major works. The coming summer will not escape the rule and many disruptions are looming for users who will stay in the Paris region in the summer.
This Tuesday, IDFM has indeed confirmed that "from June until the end of August, 5 RER lines, 7 train lines, 9 metro lines and 4 tram lines will experience work requiring temporary traffic interruptions". To avoid chaos and in order to "accompany people in their travels and especially tourists who discover the network", a display device will be deployed "in the stations and stations concerned" and information leaflets will be "distributed to travelers", promise IDFM, SNCF and RATP.

RER in Île-de-France
Reputed to be the busiest train line in Europe, the RERA will not escape the work this summer. The closures will be concentrated in August. No trains will run between Nation and Val-de-Fontenay or between Nation and Fontenay-sous-Bois between August 9 and 18. Replacement buses will make it possible to reach Paris from both stations. On the other side of the line, no trains will run between the stations of Cergy-le-Haut and Conflans-Fin d'Oise from 5 to 20 August.
Partial closures will multiply this summer on the RERB, which crosses the Paris region from North to South. The stop at Bagneux station will not be marked from May 29 to August 27 in both directions of traffic, and the line will be closed between Bourg-la-Reine and Robinson, Robinson branch, from July 22 to August 25 inclusive.
In addition, on the southern part of the line, no trains will run on the Fontaine-Michalon - Massy-Palaiseau section will be closed from 14 July to 20 August inclusive.

A little later in mid-July, the heart of the line will be closed from July 15 to August 26, and no trains will run between Avenue Henri Martin, Javel and Austerlitz stations, as well as Javel station. South of the line, the section between Pont de Rungis-Aéroport d'Orly and Massy-Palaiseau will be closed on the same dates, between 15 July and 26 August inclusive.
On the RERD, users will have to be careful from 10 to 29 July and from 31 July to 26 August, when trains will only run in one direction. On weekdays, trains will run from 4:25 a.m. to 9 a.m. in the direction of Paris, and from 16:35 p.m. to 21 p.m. in the opposite direction.
On weekends, however, trains will run to Paris in the morning until 14:55 p.m. and in the other direction from 15 p.m. at the end of the service. In both cases, the other direction of traffic will be provided by an alternative bus service.
Finally, the RERE does not escape this great summer of work. As part of the Eole project, "other service changes are to be expected," warns IDFM. In particular, 29 and 30 July, 5 and 6 August, 11 and 12 August, 19 and 20 August and 26 and 27 August, dates when Chelles Gournay station will not be served in both directions of traffic, as will Vaires Torcy station, which will not be served in the direction of Paris.

Finally, Nangis station will not be served from 3 July to 27 August. A replacement bus service is set up. In each of the cases mentioned, replacement buses will be set up.
The Transilien network also affected
If the Transilien lines are not the most central, they are still no exception to the rule, especially line J. On July 8 and 9, no train will run between Paris Saint-Lazare and Mantes, ditto from July 10 to August 13 between Epône Mézières and Mantes-la-Jolie.
Other total closures to be expected for users of the line: August 5 and 6, August 19 and 20 and August 26 and 27 between Les Mureaux and Mantes-la-Jolie, July 8 and 9 and August 12 and 13, between the stations of Issou Porcheville and Mantes-la-Jolie, and finally, August 12 and 13, August 19 and 20, and August 26 and 27, between Paris Saint-Lazare and Saint-Cloud, Garches and Marnes la Coquette.
Fewer disruptions will be expected on the rest of the network, with only one closure on line H between the stations of Ermont-Eaubonne–Valmondois and Pontoise–Persan Beaumont on 5 and 6 August, as well as on line K between Gare du Nord and Mitry-Claye from 8 July to 14 August.

Four tram lines concerned
On line T1, which connects Noisy-le-Sec station to Asnières-Quatre routes, work is also planned this summer. Result: from Monday 12 to Wednesday 14 June inclusive, the four stations La Ferme, Libération, Hôtel de Ville de Bobigny and Bobigny-Pablo Picasso will be closed.
On line T2, which connects the Pont de Bezons to the Porte de Versailles, work will be carried out at platform level, resulting in several partial closures in August. From 12 to 27 August between Pont de Bezons and La Défense, and from 12 to 18 August between Porte de Versailles and Issy–Val de Seine.
From 27 July to 11 August inclusive, line T3a - which connects the Pont du Garigliano to the Porte de Versailles - will be closed between Porte d'Italie and Porte de Vincennes. Same thing on line T3b, which usually connects the Porte de Vincennes to the Porte d'Asnières and will be closed from 14 to 26 July inclusive between the Porte de Vincennes and the Porte de Pantin.
No summer work next year
On the budget side, the sums are colossal. Some €4.2 billion has been invested in these large-scale projects, including €2.2 billion allocated to RATP and €2 billion for the SNCF network in the Île-de-France region.
Good news for next year. For the first time in several years, "there will be no work in July and August" due to the holding of the Paris 2024 Olympic and Paralympic Games. "This summer and in 2025, the work will be a little denser than other years," said Grégoire de Lasteyrie, vice-president of IDFM.
