Trains reduced due to high rail temperaturespublished at 12:49 BST
Great Western Railway has responded to heat warnings by running an amended timetable on Monday and Tuesday.
The operator has encouraged customers across the Thames Valley to prepare for changes during the hottest parts of the day, with track temperatures forecast to reach levels that require speed restrictions.
GWR said extreme heat can cause rails to expand and buckle, meaning services are required to slow down in order to ensure safety, leading to fewer trains and slightly longer journey times.
The changes will mostly impact local stopping services between Reading and London Paddington, with changes to trains serving Slough, Maidenhead and Twyford.
Due to the short-notice changes, industry information systems will not show the correct train timetable until the day of travel.
