The head of French railways has issued a warning to vulnerable passengers, advising them to avoid using trains during the current heatwave. This caution comes as temperatures are expected to peak across France early next week. Former Prime Minister Jean Castex emphasized that certain risks cannot be entirely eliminated during such extreme weather conditions. The measure aims to protect high-risk individuals from heat-related health emergencies while traveling. Authorities are monitoring the situation as the heatwave intensifies. Passengers are encouraged to prioritize their safety and seek cooler alternatives. The railway administration continues to assess the impact of the rising temperatures on infrastructure and passenger wellbeing.
