A strike by London Underground workers is set to cause travel chaos today for millions of passengers.
Members of the RMT and TSSA unions walked out at 9pm last night for 48 hours in protest at the closure of ticket offices, with the loss of several hundred jobs.
Services were hit immediately after the strike started and disruption is expected to be widespread today.
The return of wet and windy weather has led to train passengers being warned of potential travel problems. Southeastern trains said the forecast weather, after the wettest January for a century, presented a risk of further flooding, landslips and falling trees.
As a result, Network Rail has put in place a 40mph speed restriction across parts of the Southeastern network.
