Commuters have suffered severe delays on the district line this morning.
There were reports from travellers of no trains for half an hour on parts of the line.
Transport for London said there were severe delays from Edgware Road to Wimbledon due to an earlier signal failure.
It said there were minor delays between Whitechapel and Upminster.
One tweeter said it best: "Where the bloody hell is the district line this morning?"
Another said: "What signals the end of the easter break better than the district line being stuffed again. #backtonormal
