"In 1905, an unknown cameraman filmed a streetcar trip along San Francisco's Market Street. The following year, the Great Earthquake struck, and he filmed the trip again. This is a five-minute silent film that edits together excerpts of his two films. Footage from the Prelinger Archives, edited by Matt Lake."

The first electric traffic lights weren't invented until a decade after these segments were filmed.
