Here's the London Underground, as shown in Google Maps. Choose a line from the list below and click on 'Update', and the map will zoom to that line's route. Hover over stations to find out what they are.
You can use the controls on the left to move around the map and zoom in and out, or you can drag the map around to move it. You can also change the type of map using the controls at the top right; if you get a message saying 'we don't have imagery at this zoom level', then you might want to switch to 'Map' mode.
