We were going to the Tower of London and it was going to be a very simple trip on the underground with only one train transfer. We found the station easily, got to the next station when we noticed that two of the main lines were closed, today only, for maintenance. We had to back track one station, change lines, walk a quarter mile through a tunnel thdn get on another train and finally we got there! A bit queasy from motion sickness but we were at our destination.
