Is there a way to locate a map of underground London?

Transport for London, the organization responsible for running public transport in the UK's capital, publishes maps of the underground on its website. The website also offers a journey planner and status updates.

To view a map of the London underground, use the navigation on the tfl.gov.uk homepage. Select the Maps icon or click on the Maps section of the toolbar, and a list of all the maps available on the site will appear. Select Tube from this list, and a standard map of the underground will appear. Users can download a number of different versions of the map, including large print and step-free versions.
