The Phoenix Trolley Museum preserves original Phoenix trolley cars and artifacts, educating families and everyone who visits about their role in the city’s history. It showcases the story of the Phoenix streetcar, which began in 1887, marking the city’s embrace of mass transit. At its peak in the 1920s, the system covered over 30 miles, carrying millions of passengers annually. However, a fire in 1947 led to the decline of the trolley, replaced by buses as the primary mode of transportation.
