Commuters trying to reach London Bridge this morning will be facing delays due to signalling problems near Honor Oak Park.
National Rail said a fault with the signalling system between Norwood Junction and London Bridge means fewer trains are able to run on some lines.
Southern services running between these stations may be cancelled or delayed by up to 10 minutes. Disruption is expected until 09:30.
The rail operator said Network Rail, which owns and maintains the signalling and track, is currently on site investigating the signalling fault in the Honor Oak Park area and will be providing updates.
