The commentary on the film had a slight smell of government propaganda about it but it was still a great film showing a society so different from todays.
I loved it at 18.05 where they show those three boys of about 6 or 7 pretending to hold up the train. You see them walking in front of a stationary, but I assume running, locomotive brandishing toy guns.
Sure the scene is obviously posed but it shows how times have changed.
Todays woke mums would be hysterical if they saw their boys doing that. The toy gun would be enough even without the locomotive.
