Storm Eunice is causing UK-wide travel disruption as the country is battered by winds of up to 100mph.
GWR, Great Anglia and Southeastern have all suspended all services for the rest of the day; as have South Western, Chiltern Railways, and the Heathrow and Stansted Express.
In the capital, the London Underground could grind to a halt as extreme weather has affected all but two lines on the Transport for London (TfL) network.
Meanwhile, all trains from Euston station have been cancelled.
A red weather warning is now in place across various parts of the country, with turbulent winds causing havoc for pilots trying to land at Heathrow airport; earlier today, London City Airport suspended all flights.
Train operators and ferry firms are also warning people not to attempt to travel today. All rail services in Wales are suspended for the entire day, with disruption to services expected to continue into the weekend.
Rail passengers who do try to make journeys face much slower trips, with emergency speed restrictions in place and sharply reduced services.
On the Irish Sea, some ferries have been cancelled amid the wild weather.
