Southeastern is experiencing delays and cancellations across south east London and north Kent.
Signalling problems at New Cross are causing delays to trains heading to London Bridge so they are not stopping at New Cross or St Johns.
There are currently delays in the Lewisham area, and buses and the DLR are accepting tickets.
Delays are expected until at least 9am.
The 7.43 Hayes to Charing Cross, which calls at West Wickham, Catford Bridge and Lewisham, has been cancelled.
This is due to a train fault, and the earlier 6.47 service in the opposite direction was also cancelled for the same reason.
The 7.33 service into London on the same line will now be started from New Beckenham.
This train will no longer call at Hayes Kent, West Wickham, Eden Park, Elmers End and Clock House due to signalling problems.
MORE TOP STORIES The 8.39 Cannon Street to Cannon Street, which usually calls at Mottingham. Plumstead and Crayford, will now no longer call at London Cannon Street (outward at 08:39), London Bridge (outward at 08:43), New Cross, St Johns, Lewisham, Hither Green, Lee, Mottingham, New Eltham, Sidcup, Albany Park, Bexley and Crayford.
This is due to signalling problems.
The 9.09 London Victoria to Dartford service, which calls at Lewisham, Blackheath and Kidbrooke, is now running 10 minutes late.
The 7.56 service in the opposite direction is now formed of half the coaches, four.
Both are due to an earlier train fault.
SERVICE UPDATE Trains towards London Bridge are being delayed due to signal problems at Lewisham.

@Se_Railway the 633 greenhithe to cannon street is now 20 minutes late and we are just sitting at Lewisham. This is very very annoying.

@louisealdridge Sorry for the delay. This is because of signalling problem in the New Cross area. ^AW

@Se_Railway we were told ill passenger at Lewisham and track problems at New Cross. Are these excuses just made up?

Because of the signalling problems, all trains TO London won't call at #NewCross or St Johns. Trains FROM London can stop there normally
