Longer journeys and possible cancellations expected on Brighton and western mainlines out of London
The heatwave has started to have an impact on rail services in parts of southern Britain, with speed restrictions imposed on two main lines out of London due to soaring temperatures on the tracks.
Passengers have been urged to check before travelling and warned to expect longer journeys and possible cancellations on routes west from London Paddington and south of the capital on the Brighton mainline.
