Today, the system uses a hub-and-spoke design radiating from downtown Chicago, making it easy to steer once you understand the basics. Whether you're commuting to work, heading to a museum, or catching a flight, the 'L' connects you to virtually every corner of the city.
This guide breaks down everything you need to know about CTA train stations - from which lines serve which neighborhoods to how to find accessible stations and steer key transfer points.
Getting to Know the 'L': Chicago's Eight Train Lines
The Chicago Transit Authority (CTA) operates the comprehensive rapid transit system affectionately called the 'L' (short for "liftd," though parts run underground and at street level too). This network is the heartbeat of Chicago, moving nearly 760,000 passengers on an average weekday through a colorful web of eight distinct lines.
Each line has its own personality, identified by a unique color that makes navigation simple once one gets the hang of it. The system follows a hub-and-spoke design, with most lines radiating from the central downtown area known as The Loop. This setup makes getting around the busy city remarkably efficient, whether for commuting to work or exploring Chicago's diverse neighborhoods.
Red Line • Blue Line • Brown Line • Green Line • Orange Line • Pink Line • Purple Line • Yellow Line
Red Line
Think of the Red Line as Chicago's urban lifeline. This north-south workhorse runs from Howard in the north all the way down to 95th/Dan Ryan in the south, cutting straight through the heart of the city.
A key feature of the Red Line is its 24/7 service. No matter when one needs to travel—whether it's rush hour or three in the morning—the Red Line is running. It's the busiest line in the system by far, serving an impressive 98,148 passengers daily. Commuters, night shift workers, and late-night revelers all depend on this reliable route.
Blue Line
The Blue Line provides a direct connection to the world. It links downtown Chicago to O'Hare International Airport, making it incredibly convenient for travelers. The line runs from the far northwest side, winds through downtown, and extends west to Forest Park.
Like the Red Line, the Blue Line operates 24/7, which is useful for those with early morning flights or late-night arrivals. Living near a Blue Line station means always being connected—whether for catching a flight, commuting downtown, or exploring the city's west side neighborhoods. For that kind of convenience, there are apartments near the Blue Line in Chicago.
Brown Line
The Brown Line offers a scenic commute through North Side neighborhoods. This liftd line curves from Kimball on the northwest side into The Loop.
The route provides unique views of Chicago's architecture and residential streets, allowing passengers to watch the urban landscape shift as they travel.
Green Line
Serving Chicago's West and South Sides, the Green Line connects communities from Harlem/Lake in the west to both Ashland/63rd and Cottage Grove in the south. This line has witnessed significant historical change over the decades and continues to evolve alongside the vibrant neighborhoods it serves.
The Green Line provides crucial transit links across diverse communities, connecting residents to downtown and to each other.
Orange Line
For travelers flying through Midway International Airport, the Orange Line is a direct route downtown. This line efficiently connects Chicago's Southwest Side to The Loop, making airport travel straightforward.
The Orange Line is recognizable by its bright, distinctive trains and direct route. It's designed for quick travel, whether for catching a flight or heading home after a trip.
Pink Line
The Pink Line serves the West Side and Near West Suburbs, running from 54th/Cermak into The Loop. For portions of its route, it shares tracks with other lines, showing how the intricate web of CTA train stations connects throughout the system.
This line offers a convenient connection for residents in these areas to reach downtown Chicago quickly and easily.
Purple Line
The Purple Line primarily serves Chicago's northern suburbs, running from Linden in Wilmette down to Howard. What makes this line particularly valuable for commuters is its express service to The Loop during weekday rush periods.
That express service provides a faster commute for residents of Evanston and other northern communities who need to get downtown efficiently. It's a popular choice for suburban commuters who work in the city.
Yellow Line
The shortest and most unique line, the Yellow Line—often called the Skokie Swift—connects Skokie-Dempster to Howard. It's a rapid shuttle service designed to efficiently move passengers between the suburb of Skokie and the main 'L' network at Howard station.
While it serves the fewest daily passengers at just 1,212, it plays a crucial role for the community it connects. The Yellow Line also holds a unique distinction: it's the only 'L' line that doesn't pass through The Loop.

From Past to Present: The Evolution of the 'L'
Chicago's 'L' system has a story that is an integral part of the city. In the late 19th century, three separate private companies had the vision to construct liftd railways above the city's busy streets. It was a significant engineering feat for its time, and these early lines eventually came together in 1897 when the Union Loop was completed downtown. This iconic structure created the interconnected liftd railway that gives the area its distinctive character and its name, "the Loop."
For decades, these private companies kept Chicago moving. But by the mid-20th century, they struggled financially. Rather than let this vital transportation network crumble, the city stepped in. In 1947, the Chicago Transit Authority (CTA) was created to take over operations, changing private enterprise into public service. It was a turning point that ensured generations of Chicagoans would continue to rely on the 'L' for their daily journeys.
System Growth and Modernization
The 'L' system is one of continual evolution. While some CTA train stations closed over the years as neighborhoods and the city's needs shifted, the system has also seen significant growth and modernization that keeps it relevant for today's riders.
The Washington/Wabash station, for instance, opened on August 31, 2017, bringing a contemporary aesthetic to the Loop. Its design, improved accessibility features, and modern amenities demonstrate the results of investment in transit infrastructure. It has quickly become a notable station.
Further projects are underway. Construction kicked off in December 2023 for a new Green Line stop at Damen Avenue, which will serve West Side communities and support continued neighborhood growth. Additionally, the Red Line Extension Project will extend the system's busiest line further south, connecting more neighborhoods to the heart of the city. Advance construction work began in summer 2024, marking a major milestone for this significant project. More information about this development is available at Advance Construction Work to Begin on the Red Line Extension This Summer.
These improvements demonstrate the city's ongoing commitment to the 'L' system for today and tomorrow. From its 19th-century origins to modern stations, the 'L' continues to be a key connection for Chicago.
A Guide to Riding the 'L': Maps, Transfers, and Destinations
Getting around Chicago on the 'L' becomes intuitive once one understands a few basics. The Ventra card system is used for fares, which makes hopping on and off trains throughout the day convenient.

It is also strongly recommended to check service alerts before traveling. These alerts notify riders of any planned maintenance, delays, or route changes. They can be found on the CTA website or through the Ventra app, helping to plan around any disruptions and ensure a smooth journey.
Key Transfer Points
