Rush hour commuters have faced a difficult journey home on the trains after a trespasser at Charing Cross caused chaos.
Pictures published online show long queues of commuters at London Bridge after trains were diverted when the power to the railway between Waterloo East and Charing Cross was switched off.
There were also delays on the London Overground as well as the Piccadilly, Victoria, Bakerloo and Central lines on the tube as the evening rush-hour got underway on Thursday.
The Central Line continues to suffer delays due to an ongoing shortage of trains, while a signal failure at Kensal Green is causing minor issues on the Bakerloo Line.
Elsewhere there were delays on the A1 Holloway Road southbound, near Drayton Park, due to a crash.
