Overview
- SNCF, which reported a track switch failure Thursday near Saint‑Florentin on the LGV Sud‑Est high‑speed line, saw major delays across Paris–southeast routes.
- Trains were sent onto slower classic lines, pushing some waits to about three hours, including a Paris–Zurich service listed at 3h10 late.
- SNCF Réseau said around 14:00 that temporary repairs were complete and trains were moving in both directions, with full repairs planned overnight.
- Service plans shifted on some runs, such as TGV Inoui 6155 ending at Marseille instead of continuing to Toulon and Hyères.
- SNCF offered free exchanges and refunds and advised some travelers to delay trips, a standard step when high‑speed gear fails and ripples slow the wider network.
