MetroLink ( reporting mark BSDA) is the light rail transit system in the Greater St. Louis area of Missouri and the Metro East area of Illinois. The system consists of two lines (Red Line and Blue Line) connecting Lambert-St. Louis International Airport and Shrewsbury, Missouri with Scott Air Force Base near Shiloh, Illinois through downtown St. Louis. The system features 38 stations and carries an average of 53,123 people each weekday.  As of the first quarter of 2015, it is second only to Minneapolis Metro Transit's Blue and Green lines in the Midwestern United States in terms of ridership, and is the 11th-largest light rail system in the country.

Construction on the initial MetroLink alignment from Lambert-St. Louis International Airport to the 5th & Missouri station in East St. Louis began in 1990. The initial 17-mile (27 km) segment with 19 stations opened on July 31, 1993 between the North Hanley and 5th & Missouri stations.  Service was operated with 31 high-floor light rail vehicles.  About 14 miles of the original 17 miles were on existing rail right-of-way. The first phase of MetroLink was complete when the line was extended westward to Lambert Airport Main station on June 25, 1994.   At that time another station, East Riverfront, was opened in East St. Louis.  Four years later, in 1998, the Lambert Airport East station was added.  The capital cost to build the initial phase of MetroLink was $465 million. Of that amount, $348 million was supplied by the Federal Transit Administration (FTA). 
Construction on the St. Clair County MetroLink extension from the 5th & Missouri station to the College station in Belleville began in 1998 and opened in May 2001. The extension added eight new stations and seven park-ride lots. The total project cost was $339.2 million, with the FTA and St. Clair County Transit District sharing the burden at 72% ($243.9 million) and 28% ($95.2 million), respectively. Local funding was provided by the St. Clair County Transit District as a result of a 1/2 cent sales tax passed in November 1993. 
In May 2003, a 3.5-mile (5.6 km) extension from Southwestern Illinois College to Shiloh-Scott station opened. This $75 million project was funded by a $60 million grant from the Illinois FIRST (Fund for Infrastructure, Roads, Schools, and Transit) Program and $15 million from the St. Clair County Transit District. 
The Cross County Extension from Forest Park-DeBaliviere station to Shrewsbury-Lansdowne-I-44 station opened to the public on August 26, 2006Washington University, Clayton, the popular Saint Louis Galleria shopping center, Maplewood, and Shrewsbury to the system.  The entire project was funded by a $430 million Metro bond issue. Metro cited repeated delays and cost overruns as its reasons for firing its general contractor in Summer 2004. Metro sued the Collaborative for $81 million for fraud and mismanagement. The Collaborative counter-sued for $17 million for work that Metrolink hadn't yet paid for. On December 1, 2007, a jury voted in favor of the Cross County Collaborative, awarding them $2.56 million for work as yet unpaid for.. This 8-mile (13 km), 9-station extension connected
On October 27, 2008Emerson Park to Fairview Heights. All trains have a red or blue sign on the front that identify the train as a Red Line or Blue Line train, and all operators make station announcements identifying the Red Line or Blue Line.  , Metro renamed the two MetroLink lines using color designations: the Lambert Airport branch was renamed to the Red Line; the Shrewsbury branch, the Blue Line. Service was also extended on the Blue Line from its former terminus at

The main Metrolink alignment begins at Lambert St. Louis International Airport, making stops at the main and east terminals. It then proceeds through Berkeley before making a stop at North Hanley north of Bel-Ridge. It then makes two stops ( UMSL North & South stations) at the University of Missouri St. Louis campus located in Normandy. After leaving the University of Missouri St. Louis, the line continues along the old Wabash Railroad right-of-way until Grand Avenue.   Along this right-of-way stops are made in Pagedale at St. Charles Rock Road and in Wellston, before crossing the county line at Skinker Boulevard; and making a stop at Delmar, serving the popular Delmar Loop area that straddles the St. Louis/University City border. It meets up with the Blue Line at the Forest Park-DeBaliviere station. From this station on until the Fairview Heights station, it shares tracks with the Blue Line. The line is a total of 38 miles with 29 stations. For the rest of the Red Line, see "Shared alignment".
The Blue Line starts in Shrewsbury just to the west of River des Peres. It crosses Interstate 44 and then continues northeast till the next 2 stations located in Maplewood, one at the Sunnen Industrial Complex, the other at Manchester Road. From there, it continues north to the Brentwood I-64 station located in Brentwood just south of Interstate 64. It then proceeds underneath Interstate 64, continuing to the Richmond Heights station in Richmond Heights. This station serves the popular St. Louis Galleria shopping center. Following that it proceeds to Clayton station in Clayton, serving the Central Business District of St. Louis County. From here, it continues in a tunnel right under Forest Park Parkway, making stops at Forsyth Boulevard and Big Bend Boulevard in University City, serving Washington University. It then makes a stop at Skinker Boulevard in St. Louis City, before meeting the Red Line at Forest Park DeBaliviere station. It is 24 miles long, with 22 stations. For the rest of the Blue Line, see "Shared alignment".
Both MetroLink lines meet at the Forest Park-DeBaliviere station and continue for 14 more stations east on shared tracks until the Blue Line terminates at Fairview Heights. 
From the Forest Park station, the trains continue to the Central West End station, serving the Barnes-Jewish Hospital complex and the popular Euclid Avenue shopping district. From there, it proceeds to the Grand station under the Grand Boulevard viaduct, which services the St. Louis University complex and hospital. The trains pass under the Jefferson Avenue viaduct before they enter the next station near Union Station, located underneath 18th Street just near the popular Union Station shopping mall. A short distance later, the trains stop at the Civic Center Station, with transfer to the Gateway Transportation Center and the Scottrade Center. The trains then continue to run parallel under the 14th Street and Tucker Boulevard viaducts to the elevated section of Interstate 64 until the Busch Stadium station, originally serving the old, and now the new Busch Stadium. From then on, the line goes underground through a previously abandoned tunnel that had not been in use since 1974,  with stations at 8th & Pine streets, and the Convention Center under Washington Avenue and 6th Street, serving the Edward Jones Dome and Convention Center. It then makes stops on both sides of the Eads Bridge at Arch– Laclede's Landing station and at the East Riverfront station in East St. Louis, which serves the Casino Queen Gambling Casino & Hotel. From there, it runs at-grade from the 5th & Missouri station till the Fairview Heights station in Fairview Heights, Illinois. Here, the Blue line trains terminate, and the Red line trains continue until the line terminus at Shiloh- Scott AFB station at the gate to the base in Shiloh, Illinois.
MetroLink operates a fleet of 87 light-rail vehicles composed of 31 SD-400 and 56 SD-460 vehicles. Each 90-foot (27 m), single articulated vehicle has 4 high platform doors per side and has a capacity of 72 seated and 106 standing passengers.   The cars are powered by an electric motor which gets its electricity from a catenary wire with a 750 volt supply. 
Each car has an enclosed operator cab at each end. This allows the most flexible system for managing operations, but prevents travel between cars except at stations. Each car also has separate doors for station level and track level access. In normal operations the track level doors (equipped with stairs) are unused.
The system also has two different railroad yards along the line for the storage and maintenance of light-rail vehicles: Ewing Yard is located between the Grand and Union Station stops just west of downtown St. Louis; 29th Street Yard is located between the JJK and Washington Park stops in Illinois. In October 2009, Metro had opened a paint booth facility in the Illinois railyard in East St. Louis, Illinois at a cost of $1.1 million.

MetroLink uses a proof-of-payment system. Tickets can be purchased at ticket vending machines at the entrance to all stations and must be validated before boarding the train. Single ride tickets are good for up to two hours in the direction that a passenger initially boards.  Some fares, such as monthly or weekly fares, do not need to be validated, but passengers must have the pass in their possession while riding and must show the pass to security personnel upon request. Passengers may also load fares onto a Gateway Card, a multi-use smart card that can be obtained at Metro's downtown retail store. In order to validate this fare type, passengers must tap their Gateway Card on the card reader at any validation machine before boarding. Metro is still in the process of fully implementing the Gateway Card. At full implementation, Metro plans to eliminate most paper passes and tickets, and passengers will be able to obtain a Gateway Card online or at any Metrolink Gateway vending machine at each station. Effective July 1, 2014 , the fares are as follows:
- 1 Ride Ticket-$2.50 (reduced fare-$1.25) (rail only)
- 2 Hour Pass-$3 (reduced fare-$1.50) (unlimited use on Metrobus and Rail for 2 hours only)
- 2 Hour Pass from Lambert Airport $4 (unlimited use on MetroBus and Rail)
- One-Day Pass-$7.50 (unlimited use on MetroBus and Rail)
- Weekly Pass-$27 (unlimited use on MetroBus and Rail)
- Monthly Pass-$78 (reduced fare-$39) (unlimited use on MetroBus and Rail)
Reduced fares can be purchased by seniors ages 65+, people with disabilities, and children ages 5–12. Up to three children under 5 may ride free with a fare-paying rider. Proof of age may be requested of all people riding with reduced fares. Other types of passes, such as a Semester Pass for full-time students are also available in addition to the fares listed above. 
- Daniel Boone Corridor – Clayton to Westport
- A study performed in 2000 recommended a new MetroLink line from Clayton, Missouri to Westport Plaza in Maryland Heights, Missouri. The 8–10-mile (13–16 km) line would run north from the Clayton station along the old Terminal Railroad Association of St. Louis "Central Belt" right-of-way paralleling I-170, then turn west to follow existing Union Pacific Railroad trackage operated by Central Midland Railway to Page where the line would then follow Page Avenue to Westport Plaza.   This future alignment will add up to six stations between Clayton and Maryland Heights in the I-170-Page Corridor. Metro officials have suggested that this line could be the next MetroLink extension to be built.  
- MetroNorth Corridor – Clayton to Florissant
- This 12-mile (19 km) extension project would extend the current Blue Line from Clayton to North County into Florissant. Like the Daniel Boone line, some of it will follow along the old Terminal Railroad Association of St. Louis "Central Belt" right-of-way paralleling I-170.
- MetroSouth Corridor – Shrewsbury to Butler Hill
- This 12-mile (19 km) extension project would extend the current Blue Line from its terminus in Shrewsbury further into South County beyond I-270/ I-255 to Butler Hill Road. An environmental impact study was completed in 2004; however, selection of a locally preferred alternative was deferred due to the lack of local funding sources as well as many other factors. 
- NorthSide Corridor- Downtown to Goodfellow & I-70 to St. Louis Community College-Florissant Valley
The 12-mile (19 km) extension starts north from Downtown St Louis further northwest to the Florissant Valley Community College. A study for this extension was completed in 2008 and a Locally Preferred Alternative selected.
- SouthSide Corridor – Downtown to Bayless to Butler Hill
-  The 9-or-17-mile (14 or 27 km) extension starts from Downtown to the south of St. Louis County to Bayless I-55. A study for this extension was completed in 2008 and a Locally Preferred Alternative selected. The Locally Preferred Alternative begins at the Multi-Modal Transit Center at 14th & Spruce Sts., continues south on 14th St. to Chouteau Ave., travelling west on Chouteau to Jefferson Ave., then travelling south on Jefferson to Meramec St., where it then follows a right-of-way on Interstate Highway 55 to a terminus at Bayless Ave.
