The traditional tube map provides a very distorted view of where stations actually are in relation to each other. This can often lead to longer journey times or even tube journeys that would be quicker to walk.

Real London Tube will lead to a much more efficient use of the London Underground.

Real London Tube shows how the tube map looks if it was really drawn to scale whilst maintaining all the detail of the maps application that you have come to recognise on your device..

Examples:
The conventional tube map suggests that Notting Hill Gate is the nearest central line tube station to Paddington. In fact Lancaster gate is only 0.28 miles from Paddington compared with Notting Hill which is 1 mile away.

The conventional tube map shows Wimbledon and South Wimbledon stations in very separate areas whereas in reality they are less than a mile apart.

The conventional map suggests that Mansion House and Barbican are far apart on opposite sides of the circle line. They are in fact only 0.6 miles apart. Not much more than 10 minutes walk.

Note:
Viewing your current location requires GPS.
Loading the map underneath the tube lines requires an internet connection. This isn't actually required to view the tube lines, it just makes it look better. You can always pre-cache the maps if you expect to be without an internet connection while using the app.
