This is a 1926 Chicago Surface Lines silent safety film. There are lots of busy street scenes with typical CSL 1920s streetcar operations showing rear platform loading, front exit streetcars, a conductor walking across a railway crossing before flagging the streetcar across the tracks, and unmarked street loading zones. There are numerous staged accidents with other cars or streetcars--usually where the driver drives right into another vehicle, cars running right through passengers boarding and trying to pass a streetcar on the left.
