South West Trains is warning of severe disruption across the whole network for the rest of the day as travellers are urged to avoid the service until at least after 9am.

The train company is advising passengers not to travel towards London Waterloo after a loss of all signalling in the Earlsfield area of south-west London, with many trains into London Waterloo cancelled.

Waterloo station is the UK's busiest train station.

Trains could be cancelled, delayed by up to 90 minutes until the end of service.

South West Trains have also said that a queueing system may be implemented at your local station to help us get you to where you need to go safely.

Engineers are on site and are "working hard" to fix the issue.
