There are delays on the Caterham to London Bridge Southern service due to a technical problem that took place this morning.
The problem took place at 05:50am in Purley Station.
A faulty door prevented some of the carriage doors from opening properly.
The train has been taken to a depot and a normal service is now running, however passengers are advised that there will be some disruption if they are travelling along this route.
Tickets are being accepted until 08:00am on the Thameslink service and Transport for London (TFL) buses are accepting tickets between Caterham, Purley and Croydon.
