Ver Cuevana 3. The Second World War is a black page in the history of the Belgian national railways. The company was taken over by the German occupiers and 'trains of death' transported victims of the Nazi regime to concentration camps. In this documentary from 1945 filmmaker Jacques Kupissonoff reconstructs the activities of 'Group G' that specialized in the sabotage of the railway network during the Second World War. The film includes exclusive images of wrecked railway infrastructure.
