🌡️ Heatwave: impact on public transport and advice for your journeys
In the coming days, Météo France is forecasting an exceptional episode of prolonged extreme heat, with temperatures reaching up to 40°C. In this context, here is everything you need to know to adapt your journeys and travel safely.
A possible impact on the transport network

Disruptions or adjustments to transport services, implemented to ensure safety and preserve infrastructure, may therefore occur throughout the heatwave period on:
- RER lines
