A number of train services have been cancelled today due to adverse weather conditions and expected heavy snowfall.
Southern said no trains will run between Oxted and Uckfield but it will do everything it can to run trains between London Victoria and East Grinstead.
There will also be no trains running between Hastings, Ore and Ashford International today.
Southern said trains which usually terminate at Ore will instead finish their journeys at Hastings.
It is expected that replacement buses and taxis will not be able to run due to road conditions, the firm said.
Southeastern said there will be no trains running between Hastings and Tonbridge today.
It also said given the severity of the forecast, the route is also expected to be closed tomorrow (Monday, February 8), with no replacement transport available.
Part of the line running between Hastings and London Charing Cross remains shut for almost two weeks, due to landslips.
Southeastern, which runs the route, said three separate landslips over a 150-metre stretch of track have occurred near High Brooms.
The line between Tonbridge and Tunbridge Wells will be closed until February 20.
