On the Beck Map and distortion…

The design by Harry Beck, which has stood the test of time, was first introduced in 1933. It’s success has been attributed to the ease with which it can be read, despite the lack of a consistent scale. The sprawl of the London Underground out into the suburbs means that if you were to use one scale that took in every stop, the sections showing central London would be completely¬†unreadable. The coherence of the design has seen it exported to metro systems around the world.
