London's Underground service has been plunged into chaos as Storm Eunice caused disruptions with nearly every single line.
People in London could be stranded as a result of the storms, as Transport for London (TFL) admitted they “can't say” if the underground will be suspended.
It comes as London was among swathes of the country put on red alert by the Met Office because of Storm Eunice.
As a result of the high winds Network Rail advised people not to travel unless it was essential and has stopped all trains running in and out of London Euston.
And the London Underground, relied on by millions to transport them across the capital every day, could also be suspended.
A TfL spokesperson said: “Due to the Met Office's red warning over Storm Eunice, customers are advised to only travel if essential and those who need to should check before they travel using our website and the TfL Go app.
“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.”
When asked if there was potential for the whole Tube network to be suspended, the press officer said: "I couldn't say. We wouldn't want to pre-empt anything."
Network Rail earlier 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.
Rapid response teams are clearing fallen trees and debris which are blocking lines in multiple locations on the West Coast main line."
The organisation earlier warned any services which are running would be doing so at a reduced speed to allow its drivers time to look out for hazards on the track.
In a statement the operator of Britain’s rail network, said: “The severe weather will affect journeys across the country.
“Rail companies are asking you to plan your travel for a different day and to check before you travel. You can also claim compensation if the disruption has affected you.”
James Dean, Network Rail's West Coast South route director, added: "Hundreds of engineers are out in horrendous conditions trying to maintain and protect the railway from the onslaught of this major storm.
"Because of Storm Eunice's severity we've had no choice but to close some routes as it's too unsafe to run trains."
All rail services in Wales are cancelled while trees are believed to be blocking several routes around the country.
It comes as the Severn Bridges were closed for the first time for people's safety and around 436 flights in and out of the country have been cancelled.
Planes trying to land at the UK's airports have been seen dancing in the winds as they try to land on runways.
