There are currently delays on the London Overground between London Euston and Watford Junction, and on the Bakerloo Line between Queens Park and Harrow & Wealdstone. This is following a problem in the Stonebridge Park area.
However, the National Rail website suggests that the problem should clear in the next hour or so, and suggest that trains should be running normally again by the time you are travelling to the game. However, we advise that if you are relying on these lines, that you allow a bit of extra time for the journey in case the delays knock on into the afternoon.
There are no reported problems on the Piccadilly Line to Sudbury Town.
