MetroLink (St. Louis)

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 entire system currently consists of two lines (Red Line and Blue Line) connecting Lambert-St. Louis International Airport and Shrewsbury, MO with Scott Air Force Base near Shiloh, Illinois through downtown St. Louis. The system features 37 stations and carries an average of 51,716 people each weekday.

A second line, the "Cross-County Extension", now known as the Blue Line, opened to the public August 26, 2006 (2006-08-26). This 8-mile (12.9 km), nine-station line connects Washington University, Clayton, the popular Saint Louis Galleria shopping center, and Shrewsbury to the system. Further extensions are under study, but no alignments have yet been chosen, engineered, or funded.

MetroLink is operated by the Bi-State Development Agency, operating as Metro since 2003, in a shared fare system with the MetroBus lines.
