Trains services into London have been thrown into disarray by a landslip and major signalling fault.
A landslip is causing severe disruption to trains services between London Paddington and Reading.
National Rail is reporting an “unstable area of earth” has been discovered between Twyford and Reading, which has meant that two out of the four lines have been closed.
It means trains running between Paddington and Reading could be delayed by up to 60 minutes or cancelled, National Rail says.
Affected services include Great Western Railway services, Elizabeth Line trains and the Heathrow Express. Disruption is expected until the end of the day.
Meanwhile a “major signalling fault across the whole route between London and the South Coast” has caused chaos for the south-east network, with Gatwick Express services unable to run at all.
Southern and Thameslink trains have also been impacted by the fault, including those that stop at London Victoria, which comes as wet and windy weather hit parts of southern England, where a yellow warning for “persistent rain” and possible flooding was in place on Monday morning.
