A broken down train is causing early morning disruption for South Western Railway.
The train at Surbiton station means that journeys through the area may be cancelled, delayed by up to 30 minutes or revised.
A message posted on the National Rail website said that a normal service is expected to resume at midday.
It added that the train has been moved and that the issue is not currently impacting trains to and from Hampton Court.
"You may be entitled to compensation if you experience a delay in completing your journey today," National Rail said.
"Please keep your train ticket and make a note of your journey, as both will be required to support any claim."
