Paris Gare de Lyon to Close for Modernization Over May Day Weekend 2026, Causing Major Traffic Disruption
Paris, April 16, 2026 – Gare de Lyon, a major railway hub in Paris, will undergo a complete closure from Thursday, April 30, 2026, at 8:30 PM until Sunday, May 3, at midday. This exceptional closure is necessitated by crucial modernization work, which will lead to significant disruptions in train services during the May Day weekend.
Exceptional Closure for Strategic Switch Replacement
The primary reason for this unprecedented interruption is the replacement of two strategic switch control posts. These posts are vital for the operation of RER D and train services connecting Paris with the southeastern Île-de-France region. The decades-old equipment will be upgraded to computerized systems, managed from a new control center in Vigneux-sur-Seine.
The impact on travelers will be substantial. High-speed trains, including TGV Inoui, Ouigo, Lyria, and several international connections, will not serve Gare de Lyon. Approximately 60% of long-distance traffic will be maintained, but services will be rerouted to other stations such as Montparnasse, Paris Gare de l’Est, Roissy-CDG, or Marne-la-Vallée.
RER D and Line R Severely Affected
Within the Île-de-France region, the RER D will be completely interrupted within Paris and heavily disrupted along the rest of its route. Line R will not operate between Paris and Melun, with trains terminating at Juvisy. Alternative routes will be suggested, but travel conditions are expected to remain degraded throughout the weekend.
Traffic is scheduled to resume on Sunday at midday, but residual disruptions may persist for several days as the new equipment is fully commissioned.
Travelers are strongly advised to check their travel conditions in advance and plan their journeys accordingly, as the May Day weekend is expected to be particularly challenging for commuters and travelers.
Key Information for Travelers:
- Total closure of Gare de Lyon: From Thursday, April 30 (8:30 PM) to Sunday, May 3, 2026 (midday).
- No trains: No arrivals or departures from Gare de Lyon during the closure.
- TGV services: Approximately 60% of TGV services maintained, but rerouted to other stations.
- RER D: Interrupted within Paris and severely disrupted elsewhere.
- Line R: Suspended between Paris and Melun, with services limited to Juvisy.
The modernization project aims to enhance the safety and efficiency of the railway network, ensuring a more reliable service for passengers in the long term.
