One of my very favourite blogs, The Map Room has pointed a link to the 'London Underground Map Translated into German' by Horst Prillinger. It's really great, and funny in places. I like "Kennington's" having been translated as "Ken's Hof" (which can be translated back as "Ken's Yard), and I like the clever touches elswhere in that part of the Northern Line : "Elephant and Castle" is rendered as "Elefant und Burg" which shows far better than the original English the relationship between it and its neighbour, "Burg" - "Borough." The best pun is obviously the rendering of the Bakerloo Line as "Bäker-WC."
