Some of this could be solved by telling people that Aldgate to Tower
Hill is less than 10 minutes' walk, though, as I don't think everyone
from outside London realises that - even, IMX, people who do the
journey every day.

But it doesn't matter because everyone can walk everywhere. Train
services and tube stations no longer need to be where people want to go
to. They can be 10-15 mins away and everyone just walks. Yeah, right.

So that's why the streets and stations around Covent Garden are awash with
signs encouraging passengers to go on foot...
