The colorized and reconstructed images shown are from the 1946 French war film "La Bataille du Rail," which portrays a German military train derailment during the occupation of France.
Directed by René Clément, the film was produced a year after the end of World War II to honor the sacrifice of French railway workers and resistance members who sabotaged German rail lines, disrupting the movement of troops and equipment.
In the highlighted scene, a steam locomotive pulls military equipment cars that are blown off the tracks by an explosion, causing the train to leave the rails and the wagons to tumble down the embankment.
Many of the actors were real French railway employees, adding authenticity to the film. "La Bataille du Rail" won major awards at the 1946 Cannes Film Festival and remains a key European cinematic portrayal of French resistance during the war.
