Detroit's Street Railways tells the story of public transportation in the Motor City. Dating back to 1863, when horse-drawn streetcars serviced the citizenry, public transportation in Detroit has a proud and colorful history. Early on, a host of streetcar companies carried Detroiters about their daily business. This period was followed by consolidation into one company, the Detroit United Railway, and later the establishment of the municipally owned Department of Street Railways. The Department of Street Railways, established May 15, 1922, inherited a vast system of streetcar lines throughout Detroit, the first city in the United States to establish municipally owned transit system. It was a leader and innovator in the transit industry, with continued streetcar service until April 8, 1956, when the last streetcars on Woodward Avenue were replaced by buses. When the Department of Street Railways began coach operations in 1925, the intent was to provide feeder service to the established streetcar lines, as expansion costs were prohibitive. Sadly, the program implemented to complement the city's streetcar operations led to the demise of the streetcar as the principal mode of transportation in the Motor City.

Of the rail lines created at the turn of the 20th century, in order to build interurban links through Southern California communities around metropolitan Los Angeles, the Pacific Electric grew to be the most prominent of all. The Pacific Electric Railway is synonymous with Henry Edwards Huntington, the capitalist with many decades of railroad experience, who formed the "P. E." and expanded it as principal owner for nearly its first decade. Huntington sold his PE holdings to the giant Southern Pacific Railroad in 1910, and the following year the SP absorbed nearly every electric line in the fourcounty area around Los Angeles in the "Great Merger" into a "new" Pacific Electric. Founded in 1901 and terminated in 1965, Pacific Electric was known as the "World's Great Interurban."
