Pace Pulse

A system of express bus services operated by Pace was proposed as far back as 2014. One line was to run along Milwaukee Avenue from the Jefferson Park Transit Center, serving the Blue Line and the Union Pacific Northwest Line, to the Golf Mill Shopping Center. Despite delays, the Pulse Milwaukee Line opened on August 11, 2019.

Another express bus service was planned to run from O'Hare Airport to Evanston mostly via Dempster Street. The Dempster Line opened on August 13, 2023, at a cost of $10 million; however, buses only ran on Sundays. Services on the Dempster Line began running daily on October 29, 2023.

Milwaukee Line

The Milwaukee Line (internally designated as route 100) entirely runs along Pace bus route 270 from the Jefferson Park Transit Center to the Golf Mill Shopping Center. The line primarily travels along Milwaukee Avenue.

Stations

The entire route is in Cook County, Illinois.

Dempster Line

The Dempster Line (internally designated as 101) entirely runs along Pace bus route 250 from O'Hare Multi-Modal Facility, which directly connects to O'Hare International Airport via the Airport Transit System, to a station hub on Davis Street in Evanston. The majority of the line travels along Dempster Street.

Stations

The entire route is in Cook County, Illinois.

Pace is planning to add two more Pulse lines, both of which will be located in the South Side of Chicago and the south suburbs. One line will mostly run along 95th Street from the Moraine Valley Community College to the Red Line's 95th/Dan Ryan station; another will mostly run along Halsted Street from Harvey station on the Metra Electric District line to the same Red Line station that the 95th Street Line will end.
