Trains may be cancelled or delayed this morning after something was hit on the tracks.
A statement posted on National Rail's website read that earlier this morning, a South Western Railway train "hit an obstruction" between Motspur Park and Raynes Park.
The line has since re-opened but the disruption is expected to last until at least 10am.
"You may be entitled to compensation if you experience a delay in completing your journey today," the National Rail statement read.
"Please keep your train ticket and make a note of your journey, as both will be required to support any claim."
