Pace Orion I bus #2370 was repainted for use on the "Cubs Roundtripper" service between Schaumburg and Wrigley Field, for Chicago Cubs baseball games. The bus is decorated to resemble the Wrigley Field bleachers, including the classic vines on the outfield walls. Location is outside Wrigley Field.
In later years, a Pace Orion VI bus was repainted for use on the "Cubs Roundtripper", with different images of Wrigley Field. When no game was being played, the bus could appear on any Pace Northwest route. In this case, the #250 Dempster route, seen at the O'Hare Airport "Kiss and Fly" terminal.
Pace eventually started operating special bus service to Chicago White Sox games. Including with this Orion VI bus, painted with an image of the exploding scoreboard. When no game was being played, the bus could appear on any Pace Southwest route. In this case, the #386 Harlem route, seen at the Midway Airport transit terminal.
Some Pace bus routes in Du Page County were once operated by Laidlaw, formerly Vancom, now First, using these Bluebird Buses.
Operated independently from Pace for many years was the Grove Commuter Shuttle, serving Downers Grove. Eight 40 foot Gillig "Phantom" buses were built in 1992, and numbered 11, 12, 13, 15, 16, 17, 18, and 20. Buses were also available for charter service during the mid day. One charted bus is parked near the Adler Planetarium, south of downtown Chicago. In 2005, these buses were replaced with buses acquired second hand from Pace. Those 40 foot Ikarus buses were built in 1992, and renumbered 11, 12, 13, 17, 18, and 20.
