National Rail is warning passengers that hot weather could disrupt services across parts of southern England.
Temperatures are forecast to reach up to 35C in parts of the country during the UK's fourth heatwave, which starts today (Wednesday, July 29)
The heat can cause overhead power lines to expand and sag, spark line-side fires and lead steel rails to buckle, forcing trains to run at reduced speeds and increasing the risk of delays and cancellations.
Passengers are urged to check before they travel, allow extra time for journeys and carry water, with refill points available at Network Rail managed and some larger stations.
Anyone feeling unwell is advised not to board a train and to seek assistance from station staff or use help points on platforms.

Customers delayed by the conditions may be entitled to compensation for disrupted journeys.
Meanwhile, the UK Health Security Agency has issued an amber heat-health alert for the south east, which will remain in place between Tuesday and Thursday.
July has been 3C above average across the UK, according to provisional Met Office data, potentially putting it among the hottest three or four months of July on record.
Fire chiefs said people should report any signs of fire immediately by calling 999 and asking for the fire and rescue service.
They said wildfires are caused by everyday human activity, adding that “disposing of cigarettes safely, avoiding the use of disposable barbecues in open spaces and taking litter home can significantly reduce the risk of fires starting”.
