Austrian police say more than 3,000 migrants and refugees crossed into Austria overnight at Nickelsdorf, the main border point with Hungary.

They say a train carrying 400-500 left for Vienna early Thursday but most remain at Nickelsdorf.

Interior Ministry spokesman Karl-Heinz Grundboeck says authorities are meeting to discuss whether further special trains will be sent to the border for transport to Vienna's Westbahnhof terminal.

Most of those arriving there since the influx began on the weekend have chosen to continue on to Germany.
