Line H of the Transilien is experiencing disruptions and traffic interruptions? Find all the latest information here, in real time, on work, strikes and industrial action in the Paris region.

Line H of the SNCF Transilien network, opened in 2001, serves the north of the Île-de-France region over a 138-kilometer route with 46 stops. Linking Gare du Nord in Paris with many towns in Val d'Oise (95) via Seine-Saint-Denis (93), it shares part of its route with RER line C and extends as far as Oise, a neighboring département. This line, which is regularly affected by disruptions due to strikes or industrial action, also offers numerous connections with the RATP and SNCF networks: metro lines 2, 4, 5 and 7, RER lines B, C, D and E, tramways T1, T8 and T11 and transilienne lines J, K and P.

From line H, you can reach several key towns, including Saint-Denis, home to the Stade de France, and the Basilique Saint-Denis, which houses the royal necropolis where the kings and queens of France are buried. In the Val d'Oise, this Transilien train brings us close to several treasures of theÎle-de-France region, including theAbbaye de Royaumont and theAbbaye de Maubuisson, the forest of Montmorency, and the town of Auvers-sur-Oise, to the delight of Impressionist art lovers.
