CHICAGO STREET RAILWAYS - 1893
1893 was the year of the Columbian Exposition, the World's Fair celebrating Christopher Columbus's voyage to America 500 years earlier. And Chicago's transportation system had been expanded considerably prior to then. Most of Chicago's street railways were still horse powered, shown in green. The major routes meanwhile used cable cars, first introduced in 1882, and shown in blue. Meanwhile, electric streetcars had just been developed, and had been introduced on the far south side and far west side, shown in red. Eventually, electric streetcars would replace all horse cars and cable cars.
Separate panels show transit routes on Chicago's north and south sides.
