What is the Oldest Line in Chicago?

The oldest line in Chicago is the South Side elevated, a foundational component of the city's iconic 'L' train system.

Historical Roots of Chicago's 'L'

The South Side elevated railway holds the distinction of being the first section of Chicago's extensive rapid transit network. Its original portion was a significant engineering feat of its time, designed to serve the city's burgeoning population and commerce.

• Initial Completion: The line first opened to the public in 1892, with service running between Congress Street and what was then known as 39th Street (now Pershing Road). This initial segment laid the groundwork for future expansions of the elevated system.
• World's Fair Extension: Demonstrating its immediate importance to the city's growth and events, the line was further extended in 1893 to accommodate the vast crowds attending the World's Columbian Exposition. This extension cemented its role as a vital transportation artery.

The development of the South Side elevated line played a crucial role in shaping Chicago's urban landscape and its reputation as a major American metropolis. Today, parts of this historic line continue to serve commuters and visitors, primarily integrating seamlessly into the modern CTA Green Line.
