Just had an interesting question by email though which someone may know the answer to: Richard Durkan would like to know where he can get hold of a map which shows the mileage between the different tube stations.
I don't think one exists - there's lots of debates about geographically correct tube maps and I've seen a map that shows walkways between tube stations - but distances??
Incidentally, one of the most interesting things I learnt in last night's lecture is that Transport for London are commissioning a London Bus Map and are looking to invest over �50 grand in the design. Makes poor old Beck's initial twenty guineas (a few hundred quid at the time) for his map pretty damn paltry.
