It's not every day you see a set of escalators or a tube station entrance quite as eye-catching as Canary Wharf. When it is 2.30am on a Saturday morning, it becomes even more so, as there are no people about to distract you from the extraordinary architecture. Just as with New Street station, I couldn't resist B&W treatment with a dash of selective colour - as inspired by fellow Flickrite Mark Waidson.
