Chicago, the Windy City, is renowned for its towering skyscrapers, deep-dish pizza, and vibrant cultural scene. However, beneath the bustling streets and along its iconic skyline runs a critical artery that keeps the city alive: its train systems. The Chicago trains, encompassing the Chicago Transit Authority’s (CTA) elevated and subway “L” trains, the Metra commuter rail, and the South Shore Line, form a complex network that has shaped the city’s growth, economy, and identity for over a century. In this in-depth news story, we explore the history, current state, challenges, and future of Chicago’s trains, offering a detailed look at why they remain the backbone of the city’s transportation infrastructure.
A Storied History: The Birth of Chicago Trains
The story of Chicago trains begins in the late 19th century, when the city was emerging as a major industrial and commercial hub. On June 6, 1892, the first elevated train, operated by the Chicago and South Side Rapid Transit Railroad, ran from Pershing Road and State Street to Congress Street and Wabash Avenue. This marked the debut of the CTA’s “L” system, a network that would become synonymous with Chicago’s urban landscape. Notably, Chicago is the only major U.S. city with elevated trains running through its downtown Loop, a feature that has become a cultural icon, celebrated in films, literature, and photography.
The early “L” trains were powered by steam locomotives, but by the early 20th century, electrification transformed the system, making it faster and more efficient. The system expanded rapidly, with lines branching out to serve neighborhoods like Logan Square, Englewood, and Ravenswood. By the 1940s, the CTA was formed to consolidate various private transit companies, creating a unified public transit system that included both elevated and subway lines.
Meanwhile, commuter rail services, now known as Metra, began to take shape in the 19th century to connect Chicago’s suburbs to the city. The Illinois Central Railroad, Union Pacific, and other lines laid the groundwork for what would become a sprawling network serving millions of commuters annually. The South Shore Line, established in 1903, added another layer, connecting Chicago to Northwest Indiana and South Bend, offering a vital link for both daily commuters and intercity travelers.
This historical foundation set the stage for Chicago’s trains to become a defining feature of the city, enabling its growth as a major metropolis. However, as we move into the modern era, the system faces new challenges and opportunities.
The Modern Chicago Train Network: CTA, Metra, and South Shore Line
Today, Chicago trains encompass three primary systems, each serving distinct roles in the city’s transportation ecosystem. Let’s break down each component.
The CTA “L” System: The Heart of Urban Transit
The CTA operates eight color-coded lines—Red, Blue, Green, Brown, Orange, Purple, Pink, and Yellow—covering 145 stations and 224 miles of track. The Red and Blue lines, which include subway sections, operate 24/7, making Chicago one of the few U.S. cities with round-the-clock rail service. In 2019, the “L” system recorded approximately 230 million passenger trips, underscoring its role as a vital lifeline for residents.
The “L” is particularly iconic for its elevated sections, especially in the downtown Loop, where trains rumble above the streets, offering riders stunning views of the city’s architecture. The system serves diverse communities, from the bustling North Side to the historic South Side, connecting residents to jobs, schools, and cultural landmarks like Millennium Park and Wrigley Field.
However, the CTA faces significant challenges. Aging infrastructure, frequent delays, and safety concerns have drawn criticism. For instance, a 2025 post on X highlighted the CTA’s lack of expansion in the past 30 years, calling out the proposed Red Line Extension as an expensive project with questionable benefits. Despite these issues, the CTA remains a critical component of Chicago’s identity, with ongoing efforts to modernize and improve service.
Metra: Connecting the Suburbs to the City
Metra, the commuter rail system, operates 12 lines serving over 240 stations across the Chicago metropolitan area, stretching into Wisconsin and Indiana. In 2025, Metra assumed control of Union Pacific’s three Chicago-area lines, a significant milestone in its evolution. With over 80 million annual passenger trips pre-pandemic, Metra is essential for suburban commuters traveling to downtown Chicago for work or leisure.
Metra’s lines, such as the BNSF Line to Aurora and the Union Pacific North Line to Kenosha, Wisconsin, provide reliable service to far-flung suburbs. The system is known for its double-decker trains and comfortable seating, catering to longer commutes. However, Metra has faced scrutiny for its fare structure and limited service frequency, particularly on weekends, which can inconvenience riders.
South Shore Line: Bridging Chicago and Indiana
The South Shore Line, operated by the Northern Indiana Commuter Transportation District (NICTD), connects Chicago’s Millennium Station to South Bend, Indiana, serving 19 stations along the way. This intercity rail line is unique for its blend of commuter and regional service, catering to both daily workers and tourists visiting destinations like Michigan City and the Indiana Dunes.
Recent upgrades, including double-tracking projects to reduce travel times, have bolstered the South Shore Line’s efficiency. However, like the CTA and Metra, it grapples with funding constraints and the need for infrastructure modernization.
Challenges Facing Chicago Trains
Despite their critical role, Chicago trains face numerous challenges that impact service quality and rider experience. These issues, if unaddressed, could hinder the systems’ ability to meet the needs of a growing city.
Aging Infrastructure
Much of Chicago’s train infrastructure dates back decades, with some sections of the CTA’s “L” system over a century old. Tracks, stations, and rolling stock require constant maintenance, and delays in upgrades can lead to service disruptions. For example, the CTA’s Red Line, one of the busiest, has faced criticism for slow zones caused by deteriorating tracks, reducing train speeds and increasing travel times.
Metra and the South Shore Line also contend with aging equipment. While both systems have invested in new railcars and locomotives, funding limitations often slow progress. A 2024 report noted that federal and state funding for transit infrastructure has not kept pace with inflation, leaving Chicago’s trains in a constant state of catch-up.
Funding and Political Hurdles
Public transit in Chicago relies heavily on government funding, fare revenue, and taxes. However, declining ridership post-pandemic and rising operational costs have strained budgets. The CTA’s proposed Red Line Extension, which aims to extend service to 130th Street on the South Side, has ballooned in cost to over $3.6 billion, drawing accusations of being a “boondoggle” that could divert funds from other critical projects.
