I recently came across some tourist with a huge suitcase at Praed Street who, upon being told that he should have gone to Bishop's Road to get to Hammersmith started dragging his case in that direction instead of going via Edgware Road - despite being told it would be a lot easier and even quicker!:roll:
So I'd say it still needs each station to have a distinct identity in the first place.
Yes, it also needs American tourists to listen to what is being explained to them, but that's another subject altogether...
