Severe disruption is expected across Network Rail’s Southern Region on Sunday (9 February), as Storm Ciara blows in with 80mph winds.
As a result passengers are being advised not to travel.
If passengers decide to travel they are warned that there is a high risk of significant disruption.
Strong winds from Storm Ciara means there is the potential danger from fallen trees and other debris landing on the railway. Therefore a 50mph speed restriction on trains is planned to cover most of the region, which includes lines heading to the coast from London Waterloo, London Victoria, London Charing Cross and London Bridge.
Disruption is expected to last at least until the end of the day and potentially into Monday morning too.
Passengers are advised not to travel on Sunday and to check before they travel on Monday.
Operators affected include Southern, Thameslink, Gatwick Express, Southeastern and South Western Railway.
