Metra is the primary commuter rail system in the Chicago metropolitan area serving the city of Chicago and its surrounding suburbs via the Union Pacific Railroad, BNSF Railway, and other railroads. The system operates 242 stations on 11 rail lines. It is the fourth busiest commuter rail system in the United States by ridership and the largest and busiest commuter rail system outside the New York City metropolitan area. In 2022, the system had a ridership of 23,726,400, or about 154,200 per weekday as of the third quarter of 2023. The estimated busiest day for Metra ridership occurred on November 4, 2016—the day of the Chicago Cubs 2016 World Series victory rally.
The Illinois Zephyr and Carl Sandburg are a pair of passenger trains operated by Amtrak on a 258-mile (415 km) route between Chicago and Quincy, Illinois. As Illinois Service trains, they are partially funded by the Illinois Department of Transportation. Between Chicago and Galesburg, Illinois, the trains share their route with the California Zephyr and Southwest Chief; the remainder of the route (Galesburg–Quincy) is served exclusively by the Illinois Zephyr/Carl Sandburg.
The Union Pacific North Line (UP-N) is a Metra line in the Chicago metropolitan area. It runs between Ogilvie Transportation Center and Kenosha, Wisconsin; however, most trains terminate in Waukegan, Illinois. Although Metra owns the rolling stock, the trains are operated and dispatched by the Union Pacific Railroad. This line was previously operated by the Chicago & North Western Railway before its merger with the Union Pacific Railroad, and was called the Chicago and North Western Milwaukee Division and then the Chicago & North Western/North Line before the C&NW was absorbed by Union Pacific in April 1995. It is the only Metra line that travels outside Illinois.
The Union Pacific West Line (UP-W) is a Metra commuter rail line operated by Union Pacific Railroad in Chicago, Illinois and its western suburbs. Metra does not refer to its lines by particular colors, but the timetable accents for the Union Pacific West line are "Kate Shelley Rose" pink, honoring an Iowa woman who saved a Chicago & North Western Railway train from disaster in 1881. Green and yellow were already selected for the Union Pacific North Line and Union Pacific Northwest Line, respectively, so pink was chosen for this line. Therefore, the UP-W is the only Metra line that uses a color to honor a person instead of a fallen flag railroad. Until the late 1940s the line had a branch to Freeport, Illinois. It diverged from the main line at West Chicago and had stations at Elgin, Marengo, Belvidere, Rockford, Freeport, and other communities. The line was once known as the Chicago & Northwestern/West Line until UP took over the C&NW in 1995. All Metra trains on this line terminated at Geneva until 2006, when the line was extended to its present terminus in Elburn. The line runs as part of the Union Pacific Railroad's Geneva Subdivision.
The Union Pacific Northwest Line (UP-NW) is a commuter rail line provided by Metra and operated by the Union Pacific Railroad in Chicago, Illinois and its surrounding suburbs. While Metra does not refer to any of its lines by colors, the timetable accents for the Union Pacific Northwest Line are bright "Viking Yellow," honoring the Chicago & North Western Railway's Viking passenger train.
The North Central Service (NCS) is a Metra commuter rail line running from Union Station in downtown Chicago through northwestern and far northern suburbs to Antioch, Illinois. In December 2022, the public timetable shows seven weekday departures from Chicago. This line does not run at all on weekends or holidays. While Metra does not explicitly refer to any of its eleven routes by colors, the NCS' timetable accents are lavender, a shade of purple. It is one of two Metra lines that do not have a specific color for a fallen flag railroad that used to operate on the route.
The Milwaukee District North Line (MD-N) is a Metra commuter rail line in Chicago, Illinois and its northern suburbs, running from Union Station to Fox Lake. Although Metra does not refer to any of its lines by color, the timetable accents for the Milwaukee District North line are pale "Hiawatha Orange" in honor of the Milwaukee Road's Hiawatha passenger trains.
The Milwaukee District West Line (MD-W) is a Metra commuter rail line in Chicago, Illinois, and its western suburbs. Metra does not refer to any of its lines by a particular color, but the timetable accents for the Milwaukee District West line are dark "Arrow Yellow," honoring the Milwaukee Road's Arrow passenger train. Trains are dispatched from the Canadian Pacific Kansas City Railway's American headquarters in Minneapolis.
The Heritage Corridor (HC) is a Metra commuter rail line in Chicago, Illinois, and its southwestern suburbs, terminating in Joliet, Illinois. While Metra does not refer to its lines by colors, the Heritage Corridor appears on Metra timetables as "Alton Maroon," after the Alton Railroad, which ran trains on this route. The name Heritage Corridor refers to the Illinois and Michigan Canal Heritage Corridor. Established in 1984, it runs parallel to the line.
The SouthWest Service (SWS) is a Metra commuter rail line, running southwest from Union Station in downtown Chicago, Illinois, to Manhattan, Illinois. Metra does not refer to its lines by color, but the timetable accents for the SouthWest Service line are "Banner Blue," for the Wabash Railroad's Banner Blue passenger train. The trackage is owned by Metra north of a junction with the Belt Railway of Chicago at Loomis Boulevard, and is leased from Norfolk Southern Railway south of the junction.
The Rock Island District (RI) is a Metra commuter rail line from Chicago, Illinois, southwest to Joliet. Metra does not refer to its lines by color, but the timetable accents for the Rock Island District line are "Rocket Red" in honor of the Chicago, Rock Island and Pacific Railroad's Rocket passenger trains.
The Metra Electric District is an electrified commuter rail line owned and operated by Metra which connects Millennium Station, in downtown Chicago, with the city's southern suburbs. As of 2018, it is the fifth busiest of Metra's 11 lines, after the BNSF, UP-NW, UP-N, and UP-W Lines with nearly 7.7 million annual riders. While Metra does not explicitly refer to any of its lines by color, the timetable accents for the Metra Electric District are printed in bright "Panama orange" to reflect the line's origins with the Illinois Central Railroad (IC) and its Panama Limited passenger train. Apart from the spots where its tracks run parallel to other main lines, it is the only Metra line running entirely on dedicated passenger tracks, with no freight trains operating anywhere on the actual route itself. The line is the only one in the Metra system with more than one station in Downtown Chicago, the only line with no stations in fare zone 4, and also has the highest number of stations (49) of any Metra line.

It is operated by BNSF Railway as the easternmost part of the railroad's Northern Transcon to Seattle, Washington. This line is known as the Racetrack because it is mostly triple-tracked and supports fairly fast trains. It had been operated by a BNSF ancestor, the Chicago, Burlington and Quincy Railroad, which introduced high-speed Zephyr passenger trains in 1934 and ran many of them along this subdivision from Chicago to points west.
