According to Metro, there are only about 80 miles of corridors being considered. Commuter rail lines were in Metro's plans in 1994 when voters approved a one-fourth cent transit sales tax, but official dropped them later because the cost was not worth the benefit and the fare would be expensive.

Two routes have been identified, one between Downtown St. Louis and Alton, IL, and the other from Downtown St. Louis to Eureka or Pacific, MO. Though these projects are included as plan options, they are not included in the capital investment strategy. They depend entirely upon the success of Federal and State initiatives to build intercity, high-speed rail connections between Chicago, St. Louis and Kansas City.
