Overview
- The closure, which began Thursday at 8:30 p.m., suspends all Gare de Lyon trains until Sunday around midday.
- SNCF Réseau is replacing legacy switches and signals with a digital system that will link more than 1,500 devices to a new control post due Sunday afternoon.
- About 60% of usual traffic is running from five other Paris-area stations — Austerlitz, Gare de l’Est, Montparnasse, Charles-de-Gaulle Airport and Marne-la-Vallée.
- Trenitalia cut its weekend plan to roughly one-third of normal because capacity at Marne-la-Vallée is limited.
- Roughly 400,000 travelers are affected over the holiday weekend, with some redirected to Marne-la-Vallée about 40 km east to board TGVs.
