Are you one of thousands of tube passengers suffering from claustrophobia and/or anxiety? Journeys across the capital could be made that little bit easier, thanks to this map from TfL.
It might look like a pretty ordinary map, but look closer and you'll notice that all track that passes through tunnels is highlighted in grey.
As any Londoner worth their salt will tell you, more than half of the tube's 270 stations are overground (not to mention significant strips of the DLR and Overground).
TfL hopes this map will help those who prefer to minimize travelling through tunnels on their journeys, to plan out an appropriate route (even if it does take that little bit longer to get from A to B).
The map is part of a variety of special tube maps, available to download.
