Today, authorities in Budapest, Hungary halted all international trains out of the capital after refugees and migrants rushed the cars. In recent days, more than two thousand were forced to camp out at the station; others were stranded on trains in route. They're among tens of thousands fleeing conflict in the Middle East and Afghanistan, trying to reach Germany and other Northern European countries. Anemona Hartocollis, who's following the story for the New York Times, is in Budapest watching this all unfold.
