Get live information about the London Underground with the Tube Status assistant app. Plan your trip and find out about delays and disruptions that may affect your journey. The Line Status assistant app is the quickest way to find out if there are delays on the Central line or partial closure on the District line. If there is a good service across the whole Underground network the app will also reassure you that everything is running smoothly.
