3D London Tube Map Update

A quick update on the real 3D tube map of London. Data on the depth of the tube stations is proving tricky to get hold of due to security issues. One simple way would be to count the number of steps down to each station - so if anyone on their way to work could count the steps down and email them in that would be great!



The map can then be updated as and when the number of steps are sent in..
