Delays of up to 50 minutes are building up on some Southeastern lines, with cancellations and bus replacements.
A signalling fault is believed to be behind the delays, which have affected trains between Ramsgate and Margate; Ramsgate and Faversham and Ramsgate and Ashford International.
A replacement bus service is running, with London Underground accepting tickets for some routes.
