This geographically accurate map of the London Underground would have been a good idea,back in the time. I remember visitors,walking like crazy,and me trying to convince them that walking was just a better alternative,that the other tube station was only minutes away from where we were.
Sometimes they believed me.
UPDATE:Now you have the old,traditional map of the underground,with walkways indicated. There you go:User friendly maps.
The tube was clean,but it was out of service,often. Also the lack of AC was pretty bad. Cabs were very expensive,and not always an option.
I think so.
