Travellers on an intercity train in Austria were startled on Sunday when a recording of an Adolf Hitler speech was played on board.
Instead of the normal announcements, a crowd could also be heard shouting “Heil Hitler” and “Sieg Heil” over the train’s speaker system.
The operator said there had been several such incidents in recent days.
One passenger on the Bregenz-Vienna service told the BBC that everyone on the train was “completely shocked”.
David Stoegmueller, a Green Party MP, said the speech by the Nazi German leader was played over the intercom shortly before the train, an ÖBB Railjet 661, arrived in Vienna.
