Southeastern Railway are warning that tomorrow's forecast for "extremely hot weather" will lead to significantly reduced services for fear of tracks buckling under the heat.

A statement released by the railway provider explained that metal tracks can exceed 50 degrees when exposed to direct sunlight, causing them to warp.

Due to this, speed restrictions will also be in place on Thursday, July 25 as weather forecasters predict temperatures to hit a scorching 38 degrees across the capital.

Southeastern are now "strongly" advising customers to avoid travelling if possible as this summer's heatwave continues to grip Britain.

If you are travelling tomorrow, train providers have asked that passengers "beat the heat" and always carry water.

Passengers who feel unwell while onboard a train are being asked to avoid using the emergency alarm between stations as this can cause a delay in help reaching you.

Normal services are expected to run on Friday, July 26 when temperatures are set to fall again.
