Heatwave forces SNCF to cut a quarter of Intercités services, disrupting French rail travel
Executive summary: SNCF cancelled a quarter of Intercités train departures and certain TER services due to a nationwide heatwave on July 8 2026. The cancellations disrupt passenger travel, generate revenue losses and potential compensation costs, and highlight the susceptibility of rail infrastructure to extreme heat.
Who is involved: SNCF (French national railway), passengers, regional transport authorities, and French government oversight bodies.
Likely next (inference): If temperatures remain high, SNCF may extend cancellations; it will likely process refunds and assess long‑term heat‑mitigation measures such as track cooling or adjusted schedules.
On July 8 2026, SNCF announced the cancellation of approximately 25 % of its Intercités train departures and selected TER services amid an extreme heatwave affecting much of France. The move aims to protect infrastructure and passenger safety as high temperatures can cause rail buckling and equipment overheating. While the cancellations reduce immediate operational risk, they result in lost ticket revenue, increased compensation claims, and inconvenience for travelers and regional economies. The incident underscores the growing climate vulnerability of Europe’s rail network and may prompt further investment in heat‑resilient infrastructure.
