Tube-map with "walklines"

The familiar London tube-map is hailed as an example of brilliant information design — indeed, it is — because it manages to show the logical relations between the stations clearly and consisely. However, the physical relationships between the stations are not priorities for the map's designers, which means that you can find yourself riding the tube for five stops on two different lines to go between two points that are physically only separated by a few hundred yards, though you'd never know it by looking at the map. Rodcorp has taken a standard London tube-map and added "walklines" to it, showing stations that are separated by 500 meters or less.
