The Black Hawk was an Amtrak passenger train service that operated from 1974 to 1981 between Chicago, Illinois, and Dubuque, Iowa, via Rockford, Illinois. Plans are underway to restore the route between Chicago and Rockford by 2025 as part of the Illinois Service. Restored service to Rockford was planned to begin in 2015, but was put on hold by Illinois Governor Bruce Rauner. An extension to Dubuque was to open at a later date. The service was later funded in 2019 with the support of Governor J.B. Pritzker.
