Kate Adie introduces correspondents' stories. This week, as Europe agonises over how to deal with the flow of migrants heading westwards, we hear two different perspectives from the Continent: in Vienna they've been shocked into action, while in Prague the loudest message is "keep out." Azerbaijan is spending millions on trying to improve its image but our correspondent says it should save its money and just stop locking people up. In Ireland speed, skill and passion are the order of the day on the pitch - and having a Putin-like stare helps. While on America's Amtrak network it's less a question of speed and more a matter of finding your moment of Zen.
