Extremely hot weather is forecast for Thursday 25th July, and speed restrictions will be introduced across the Southeastern rail network.
Metal rails in direct sunshine can exceed 50°C, and Network Rail need to introduce speed restrictions to reduce the chance of rails buckling in the heat.
Southeastern will be running significantly fewer services on Thursday, and many trains will be much busier than usual. Those trains that do run will take longer to complete their journeys – particularly on longer-distance routes.
They’re advising you allow extra time for your journey.
