The Train Rolls On (1973)

This half-hour documentary focuses on Medvedkin and his CineTrain of the 1930s, a sort of mobile film workshop, complete with post-production facilities, animation stations and a large laboratory. Traveling thousands of miles across the Russian countryside, the train stopped to have its filmmakers document Ukranian harvest practices, steel production facilities in southern Russia and other industrial / agricultural matters; With each crew member living in 1 square meter living quarters, all individuals on the train were responsible for various odd-jobs and other practical matters in addition to their own film-making concerns.
