Some Southern services have been diverted to Victoria, others now depart from a different platform. Please check the departure boards.
Platforms 1-6: the entrance by the interim ticket office has closed; a new route is signposted but will add a few minutes to your walk.
Platform 13 can no longer be accessed by the footbridge.
Platforms 14, 15 and 16 have closed.
The changes are to allow work for the Thameslink programme.
