'We travel into the city' - a movie with railway action

Andremo in citta was an Italian-Jugoslav co-production from 1966, the city being a concentration camp.   In German it was translated as Wir fahren in die Stadt, which version (96 minutes) is viewable free on the Internet Archive here

The poster above was for the French version - the title Le dernier train was reused later for a documentary on the same theme.
