'''Blue Line''': The second most used line, formerly the "Congress-O'Hare Line" or the "West-Northwest Line". This line, from north to south, starts in an underground station beneath the parking garage at O'Hare International Airport, travels in the middle of the Kennedy Expressway through several of Chicago's northwest sections, before a short subway that connects to a small elevated section. After this elevated section, it enters a longer subway under Milwaukee Avenue, enters downtown under Lake Street (with the only direct transfer station between the Loop and the subway), turns parallel to the Red Line on Dearborn Street, and leaves downtown heading west under Congress Street, where it emerges into the middle of another highway (Eisenhower Expressway), which it follows to the end of the line at Forest Park. This line was originally built by the Metropolitan West Side Elevated as a single line connecting to the southwestern corner of the Loop and fanning out into four elevated branches to serve the western neighborhoods. Of the four elevated branches, the "Humboldt Park" branch was discontinued in 1952, the "Garfield Park" branch was replaced when the Congress (now Eisenhower) Expressway was built (the elevated line was in the way of the planned highway), the "Logan Square" branch was connected to the newly opened Dearborn Street Subway in 1951, and the "Douglas Park" branch (now the Pink Line) was shortened and reconnected to the new Congress line. In 1970, the line was extended northwest from Logan Square over another expressway route to Jefferson Park, and in 1984 the extension to O'Hare was opened. It and the Red Line are the only two lines on the system that operate 24 hours a day.

Although it is called the L, it is perhaps the only metro system in the world that includes elevated lines, subways, and ground-level lines complete with grade crossings (just please don't touch the third rail, thank you).

'''Brown Line''': Formerly the "Ravenswood Line." This line was started as a branch off the northern section of what is now the Red Line, which zigzags to the northwest somewhat. It travels to its start point to meet the Red Line at a couple of transfer stops, then follows an elevated route to the loop, and goes around the loop back to its starting point. The routing has changed little since 1949 (before which it was through-routed with various South Side branches and used the State Street Subway once it opened), although expansion for some platforms due to greatly increased ridership were done in the early 2000's.

'''Green Line''': Consisting of a merger of the Lake St. and South Side Elevated lines. This line, from west to south, follows an elevated track from the suburb of Oak Part directly over Lake St. (one of the few major streets in Chicago not laid out along a straight line) to the loop, follows the north and east sides of the loop, and then travels almost directly south with one jog over. For the last couple of stops, the line splits, one section (part of the former "Jackson Park" branch) going a few blocks east, another section (formerly the "Englewood" branch) going west for some distance. These two sections were the oldest elevated lines built (and were the only elevated lines in Chicago to use steam locomotives), but were not merged into one line until 1993. (As mentioned in the Red Line, the western section was originally paired with the Dan Ryan section of the Red Line, while the southern section was attached to the subway and northern sections of the Red Line, these were switched to balanced the number of riders on both branches.) For two and a half years starting in 1994, the Green Line was shut down for repairs, a very controversial move.

'''Orange Line''': AKA the Midway Line or the Southwest Line. The most recently built line, finished in 1993. From the loop this line travels southwest to Midway Airport. Might have been another "middle of a highway" line (the Stevenson Expressway was built with this in mind), but was instead built alongside various freight rail tracks.

'''Pink Line''': Formed by stringing together the Douglas Branch and Paulina Connector, both of which were originally built as part of the Metropolitan West Side system. Formerly a part of the Blue Line that branched southwest from the Eisenhower section, this line was instead connected to the Green Line and sent around the Loop in 2006, to help make scheduling easier. (The line had operated this way for a few years in the 1950s.) The Paulina Connector, formerly a service track connecting the Blue Line to the rest of the system, currently has no passenger stations on it; a new station at Madison St. has been proposed to serve the United Center as part of a larger development project around the arena. If this station is built, Soldier Field would be the only major stadium in the city without direct access to the L.

'''Purple Line''': AKA the Evanston Shuttle or Express. Runs from the northern end of the Red Line through the northern suburbs of Evanston and Wilmette. During rush hours, the line follows the Red Line route express to where it meets the Brown Line, than follows the Brown Line route to the Loop, which it circles before going north again. The Wilmette terminal was built in a shady manner; people around the stop's location opposed the building of the extra stop, so construction crews quickly built tracks and platforms in the middle of the night, before later court orders declared to move legal. The choice of color for the line was made for Northwestern University, which four of its stops are two blocks west of.

'''Yellow Line''': Formerly the "Skokie Swift." Runs from the northern end west, the north into another one of Chicago's suburbs. This line was built in the 1920s as an express bypass for the interurban line to Milwaukee, which lasted until 1963; the city system operated a lightly-used local service between the suburb of Skokie and Howard Street Station between 1925 and 1948. The CTA reinitiated service on the 4.7-mile section between Howard Street and Skokie in 1964, with no intermediate stations, as an experimental project in suburban transit under the Department of Housing and Urban Development. The experimental operation became permanent, though until 2004 the line used a unique overhead catenary system instead of third rail. One intermediate station in Skokie was reopened in 2012.

Unlike many other train systems, very little of the "L" is composed of subway. In fact, the only sections of subway that do exist are the downtown portions of the Red and Blue Lines, a short stretch of the Blue Line that moves trains from the Kennedy Expressway to an elevated segment parallel to Milwaukee Avenue, and the Blue Line's terminus at O'Hare. As the name suggests, many of the lines are elevated. Three large sections of 'L' (a large portion of the Blue Line and most of the Red Line south of the Loop) run in the middle of highways, with stations connected to overpasses or with walkways over or under the highways. The CTA was the first to do this on any kind of scale, and the idea has since been taken up elsewhere. Expressways have some advantages as routes for elevated lines, since (1) they tend to already be elevated (meaning the pylons are already there) and thus (2) they are already grade-separated (meaning the trains can get their own rights-of-way), and furthermore (3) the government tends to already own the expressways, so getting the rights to build on the land isn't an issue, and (4) the expressways are already noisy and busy, so one common complaint people raise against building a line near them is simply not applicable. This comes at a trade-off of somewhat higher maintenance cost over subway, but that's true of all elevated tracks and not just those on elevated expressways.

In addition to extensions to the Red, Yellow, and Orange Lines, a "Circle Line" or "Outer Loop" has been proposed and is in planning stages. The line, which would run [[ExactlyWhatItSaysOnTheTin in a circle]] would share the same tracks as the Red Line from the near north side, through downtown, and then splitting off after coming back above ground to merge with the Orange Line. It would then run southwest along the Orange Line before splitting off and turning north at Ashland, eventually running alongside the Pink Line and continuing north past the Green Line until meeting up with the Red Line once again. The route would allow a greater amount of north-south traffic to bypass the Loop and provide more links to a number of Metra lines without having to connect downtown. As the bulk of the route will run alongside existing lines, only the sections between the Orange and Pink Lines on the southwest side and Green and Red Lines on the north side will require new track to be built. The restoration of previously unused track along Paulina St. that the Pink Line now runs on was considered to be the first phase of the project.

'''Green Line''': Consisting of a merger of the Lake St. and South Side Elevated lines. This line, from west to south, follows an elevated track from one of Chicago's western suburbs directly over Lake St. (one of the few major streets in Chicago not laid out along a straight line) to the loop, follows the north and east sides of the loop, and then travels almost directly south with one jog over. For the last couple of stops, the line splits, one section (part of the former "Jackson Park" branch) going a few blocks east, another section (formerly the "Englewood" branch) going west for some distance. These two sections were the oldest elevated lines built (and were the only elevated lines in Chicago to use steam locomotives), but were not merged into one line until 1993. (As mentioned in the Red Line, the western section was originally paired with the Dan Ryan section of the Red Line, while the southern section was attached to the subway and northern sections of the Red Line, these were switched to balanced the number of riders on both branches.) For two and a half years starting in 1994, the Green Line was shut down for repairs, a very controversial move.

Chicago's metro rail system.[[note]]Not to be confused with [[www.metrarail.com Metra]], which is the area's commuter rail system.[[/note]] Radiating from downtown, it stretches through most of the city of Chicago into some of the nearby suburbs, and carries about 600,000 riders on an average weekday. The system, along with Chicago's buses, is managed by the Chicago Transit Authority. The system's most well-known feature is "The Loop" in downtown Chicago, a square of elevated tracks over Wabash Avenue, Lake Street, Wells Avenue and Van Buren Street where most of the lines converge--indeed, "the Loop" is a common synonym for the heart of Downtown. The northwest corner of the Loop is one of the busiest rail junctions in the world, with trains from (currently) 4-5 of the 8 lines traveling in different directions at this intersection.

'''Red Line''': The most used line, known by old-timers as the "Howard-Dan Ryan Line" or the "North-South Line." From north to south, it begins on an elevated line from the city's northern boundary before descending into the State Street Subway south of Fullerton (around a couple miles north of downtown). The line follows the subway through downtown before re-emerging aboveground at Cermak-Chinatown into the middle of the Dan Ryan Expressway, which it follows to 95th Street. There are plans to extend this further to close to the southern city limits, but funding is not available for this project yet. The northern section of the line was the main line of the Northwestern Elevated (which opened a few years after the west side of the Loop was built to directly connect with it, due to many delays in construction), and it remained completely elevated until the subway opened in 1943. The Dan Ryan, southern section was built in the late 1960's, and was originally connected to the west and loop section of what is now the Green Line, while the northern route went through the subway and connected to what is now the southern Green Line, but these were switched in the early 1990's to better match the number of riders between sections. The Dan Ryan section was closed for several months, in a somewhat controversial move, for large scale track repairs. If you are a [[UsefulNotes/{{Baseball}} baseball]] fan, this is the line to know - both Wrigley Field (Addison) and U.S. Cellular Field (Sox-35th) are easily reached from this line, and it's generally believed that any (at this point, given the records of [[ButtMonkey the Cubs]] and [[EveryYearTheyFizzleOut the Sox]], ''highly'' theoretical) World Series between these teams would be termed the "Red Line Series."

Though the system's ridership has generally been increasing over the past few years, and several expansion plans exist, it still experiences financial/funding difficulties, and maintenance difficulties, with large sections of track considered "slow zone" (Some of these maintenance difficulties are likely to do the elevated and highway sections of track, which is a rougher environment for the structure than a subway or ground level line would experience). Several large structure repair projects have been done over the past few decades, including shutting down the Green Line for 2 years in the 1990's, and the Dan Ryan section of the Red Line in 2013 (These projects proved controversial, partly for obvious reasons related to loss of transit for long periods of time, and partly because these lines serve very poor neighborhoods, already experiencing a range of other problems).

'''Blue Line''': The second most used line, formerly the "Congress-O'Hare Line" or the "West-Northwest Line". This line, from north to south, starts at O'Hare International Airport, travels in the middle of the Kennedy Expressway through several of Chicago's northwest sections, before a short subway that connects to a small elevated section. After this elevated section, it enters a longer subway under Milwaukee Avenue, enters downtown under Lake Street (with the only direct transfer station between the Loop and the subway), turns parallel to the Red Line on Dearborn Street, and leaves downtown heading west under Congress Street, where it emerges into the middle of another highway (Eisenhower Expressway), which it follows to the end of the line at Forest Park.

In 1970, the line was extended northwest from Logan Square over another expressway route to Jefferson Park, and in 1984 the extension to O'Hare was opened.

* Music/{{Wilco}}'s song "Far, Far Away" (off ''Being There'') has the lyrics "I long to hold you in my arms and sway/Kiss and ride on the CTA," the CTA being the 'L' (or a CTA bus, but probably the 'L'). Wilco is of course from Chicago; the song is about missing a significant other in a far away city (so it's probably about lead singer Jeff Tweedy on the road wanting to go home to Chicago and his wife).

From north to south, it begins on an elevated line from the city's northern boundary before descending into the State Street Subway south of Fullerton (around a couple miles north of downtown).

The system started as four separate elevated lines built in the 1890's to connect different sections of the city downtown. The developers of these lines (except for the Lake Street line) sought to mitigate the obtrusiveness of elevated railroads by building them in alleys between city streets instead of directly over them. One of the builders of these lines, Charles Tyson Yerkes, decided to bring them together into the modern loop by extending the downtown endpoints until in 1897 they met in the square that exists today. These early lines gradually expanded over time, with several branches and extensions added. However, the lines had trouble making money, and the various railroad companies were merged together to form a single company in 1924. This company also experienced financial troubles after some time, and in 1947 the city took it over and established the CTA. Over the next ten years, the CTA closed several lesser branch lines (including one that served the city's notorious stockyards), sped up service by eliminating many lightly-used intermediate stations, and replaced the ancient wooden rolling stock. Financial issues have continued since, however, with the CTA regularly experiencing budget problems. Despite this, several expansions have been constructed over time, and the system's ridership in the past few decades has actually been increasing.

'''Blue Line''': The second most used line, formerly the "Congress-O'Hare Line" or the "West-Northwest Line". This line, from north to south, starts at O'Hare International Airport, travels in the middle of a highway through several of Chicago's northwest sections, before a short subway that connects to a small elevated section. After this elevated section, it enters a longer subway, that enters downtown from the northwest, makes a u-shape, and leaves straight west, where it exits into the middle of another highway (Eisenhower Expressway), which is followed to the end of the line. This line was originally built by the Metropolitan West Side Elevated as a single line connecting to the southwestern corner of the Loop and fanning out into four elevated branches to serve the western neighborhoods. Of the four elevated branches, the "Humboldt Park" branch was discontinued in 1952, the "Garfield Park" branch was replaced when the Congress (now Eisenhower) Expressway was built (the elevated line was in the way of the planned highway), the "Logan Square" branch was connected to the newly opened Dearborn Street Subway in 1951, and the "Douglas Park" branch (now the Pink Line) was shortened and reconnected to the new Congress line. In 1970, the Logan Square lie was extended northwestward over its own expressway route to Jefferson Park, and in 1984 the extension to O'Hare was opened.

The line follows the subways through downtown before re-emerging aboveground at Cermak-Chinatown into the middle of the Dan Ryan Expressway, which it follows into 95th Street. There are plans to extend this further to close to southern city limits, but funding is not available for this project yet. The northern section of the line was one of the original lines that formed the loop and was completely elevated, while the subway was built during UsefulNotes/WorldWarTwo. The Dan Ryan, southern section was built in the late 1960's, and was originally connected to the west and loop section of what is now the Green Line, while the northern route went through the subway and connected to what is now the southern Green Line, but these were switched in the early 1990's to better match the number of riders between sections. The Dan Ryan section was closed for several months, in a somewhat controversial move, for large scale track repairs. If you are a [[UsefulNotes/{{Baseball}} baseball]] fan, this is the line to know - both Wrigley Field (Addison) and U.S. Cellular Field (Sox-35th) are easily reached from this line.

'''Brown Line''': Formerly the "Ravenswood Line." This line was started as a branch off the northern section of what is now the Red Line, which zigzags to the northwest somewhat. It travels to its start point to meet the Red Line at a couple of transfer stops, than follows an elevated route to the loop, and goes around the loop back to its starting point. The routing has changed little since 1949 (before which it was through-routed with various South Side branches and used the State Street Subway after it opened), although expansion for some platforms due to greatly increased ridership were done in the early 2000's.

'''Orange Line''': AKA the Midway Line. The most recently built line, finished in 1993. From the loop this line travels southwest to Midway Airport. Might have been another "middle of a highway" line, but was instead built near freight rail tracks.

Chicago's main rail system. Radiating from downtown, it stretches through most of the city of Chicago into some of the nearby suburbs, and carries about 600,000 riders on an average weekday. The system, along with Chicago's buses, is managed by the Chicago Transportation Authority. The system's most well-known feature is "The Loop" in downtown Chicago, a rough square of elevated tracks where most of the lines converge--indeed, "the Loop" is a common synonym for the heart of Downtown. The northwest corner of the Loop is one of the busiest rail intersections in the world, with trains from (currently) 4-5 of the 8 lines traveling in different directions at this intersection.

The system started as several separate elevated lines serving different sections of the city, built in the 1890's and early 1900's, all ending in downtown. One of the builders of these lines, Charles Tyson Yerkes, decided to bring them together into the modern loop by extending the downtown endpoints until they met in the square that exists today. These early lines gradually expanded over time, with several branches and extensions added. However, the lines had trouble making money, and the various railroad companies were merged together to form a single company in 1924. This company also experienced financial troubles after some time, and in 1947 the city took it over and established the CTA. Financial issues have continued since, however, with the CTA regularly experiencing budget problems. Despite this, several expansions have been constructed over time, and the system's ridership in the past few decades has actually been increasing.

Currently in the process of transitioning from its long-established magnetic strip farecards to a new contactless payment system named Ventra. Controversial since its announcement due to the increase in fare for single-ride tickets and 5 dollar fee for issuing a new reloadable card[[hottip:*:later credited back after being registered online]], a system adapted from ones that exist elsewhere around the world and in the US (e.g. the UsefulNotes/WashingtonMetro and the [[UsefulNotes/PhiladelphiaSubways PATCO]]). The technical issues that plagued it following its initial rollout in summer of 2013 that truly caused it to become the bane of Chicago commuters' existences. The problems forced the CTA to delay the phase-out of the old farecard readers indefinitely. Once the bugs are sorted out however, it should make traveling throughout the metro area more convenient as it is planned to be adopted by suburban commuter rail system Metra by the end of 2014. This will be the first time the two rail systems, as well as the suburban Pace bus network, will all share a common payment system.
