SALZBURG, AUSTRIA - SEPTEMBER 15: Migrants wait at Salzburg Hauptbahnhof railway station for available seats on trains to Germany on September 15, 2015 in Salzburg, Austria. Train connections between Germany and Austria have been disrupted by new border controls. German authorities have temporarily reinstated border controls along Germany's border to Austria and are conducting spot checks on arriving traffic. Germany is still accepting up to thousands of new migrants daily but has imposed border controls in order to crack down on smugglers and to better regulate the flow of arriving migrants, tens of thousands of whom arrived in Germany over the last few weeks. Meanwhile Hungary has sealed it new fence along its border to Serbia and is ferrying remaining migrants to its border with Austria. (Photo by Sean Gallup/Getty Images)
