Change at Edgeware Road onto a Wimbledon train (cross-platform usually) and alight at Paddington Circle Line platform. Yes, there's an up 'n over footbridge unfortunately, but on exit, you find yourself up on the concourse
Indeed ... that's a possible solution, although alternate trains from Edgware Road require an "up and over" there too (or is that just into Circle line trains?).
Chris, is this the official advise given to people who need to visit the manned ticket desks at Paddington when arriving from Euston Square and beyond? In the days when the Circle was a (squashed) circle, it was the natural thing to do, and you could see how many minutes you had to wait when making a decision to join a Hammersmith and City service or wait for the Circle one at King's Cross
