Not very much changed at the borders of the Czech Republic and Austria from the Austrian side. The Czech Republic entered Schengen space 21th December 2007, which means obvious free movement of goods and folks. But even when the border police disappeared from borders, on the Austrian site they just spread, and they check ‘suspicious vehicles’.
The former border police comments the situation; they want to control the number of refugees. Cars, that could be carrying them, are reported by police officers in civilian cars, up the road. The Schengen Kontrolle has wide support of Austria public.
