Every train line in South East London has been blocked by trees as Storm Eunice battered the capital.
All services to Kent have been cancelled as the storm sparks travel chaos.
Network Rail said every train line in the area had been affected by the extreme weather conditions and urged Londoners not to travel.
The Mayor of London has urged people to “stay at home” and “do not take risks” as 70mph gusts hit the capital.
Sadiq Khan also told Londoners to not travel “unless absolutely essential”.
In an update on Twitter, Network Rail wrote: “UPDATE: We are closing all routes in Kent, and all lines in SE London are blocked by trees. Please do not travel.
“We will reassess the risk after 1500 on a line by line basis but it is no longer safe for our staff or trains to run.”
Update: there are 3 lines open in Sussex - London-Brighton, london-Bognor and London to Sutton. There is still major disruption on those routes, including here at Ifield, near Horsham, and our advice is to not travel. #StormEunice pic.twitter.com/frp3E2QmR7

The Southeastern rail company - which covers London, Kent and East Sussex - told passengers that trains already en route to destinations would be moved to the nearest safe location.
On Twitter, the firm said it would “soon start working with Network Rail” to check which routes may be safe to reopen.
The Network Rail Kent and Sussex account shared a tweet with a long list of train lines blocked by trees or metal objects, including Lower Sydenham Station and New Beckhenham Station.
We thought it might help explain the challenge we face this afternoon if we put out the current list of blocked routes in Kent, SE London and our route into East Sussex via Tunbridge Wells...#StormEunice pic.twitter.com/4EFlyJoBIq

Meanwhile, Network Rail also announced the cancellation of all trains running in and out of London Euston.
The organisation said: “All lines are suspended affecting services between Euston and Milton Keynes until further notice.
“The message to passengers is ‘DO NOT TRAVEL’ today as the railway network is being battered by gale force winds.”
London Ambulance Service said two people were taken to hospital after being struck by falling debris and a tree in separate incidents in Waterloo and Streatham an hour apart.
👷 We're busy clearing debris, plastic and fallen trees from our route to get trains running again as soon as possible.

Transport for London also urged people to avoid non-essential journeys in the capital.
A spokeswoman said: “We are doing all we can to ensure we are prepared for any impact, with extra staff ready to respond quickly to any incidents, but some services will be affected by the extreme weather.
“We are also urging Londoners to please take care if they travel around the city.”
