No Southern or Thameslink services will run on Friday 1 September, with a limited service on Saturday 2 September.
Trains will not be running from Uckfield, Crowborough or Haywards Heath on Friday, due to industrial action by the ASLEF union. The only Southern service will be between London Victoria and Gatwick Airport - this will not be stopping at any other stations.
On Saturday 2 September, no trains will run between Uckfield and Hurst Green, services will be running from Haywards Heath but these will be limited and likely busier than usual.
