The latest tube maps include the time it takes to walk along a line between stations in the central zones. It's not a to-scale map, but it gives some useful hints. https://tfl.gov.uk/maps/track/tube https://tfl.gov.uk/maps/track/tube The problem with making the London map topographic and to scale is that the northwest extension of the Metropolitan line stretches far out into the countryside. A to-scale map would have to shrink the central area - the most useful part of the map - which would make it cluttered and hard to read. The zone system on the map provides useful hints about absolute distance without being perfectly to-scale. That aside, most people using a metro system need to know how long it will take to get somewhere on the system more than they need to know exactly where they are. TFL's app includes journey time estimates.
