Metra proposed two routes in the early 2000s, SouthEast Service, which would connect some portions of the southern suburbs with downtown Chicago, and the Suburban Transit Access Route, which would connect various suburbs with each other without going into the downtown.
Metra mengusulkan dua rute pada awal 2000-an, SouthEast Service , yang akan menghubungkan beberapa bagian dari pinggiran selatan dengan pusat kota Chicago, dan Rute Akses Transit Suburban , yang akan menghubungkan berbagai pinggiran kota satu sama lain tanpa pergi ke pusat kota.
