[London] Tube question
If you were going northbound on the Northern Line and wanted the most efficient change to the Bakerloo Line, would you do it at Waterloo, Embankment, or Charing Cross?
I asked bob and he wasn't sure. Looking at the Tube map, the only station where the Northern and Bakerloo lines are on the same “blob” is Charing Cross — but am I misremembering that blobness is related to ease of changing?
