There isn’t a single “trolley schedule” for downtown Chicago, because the city’s free trolley service has multiple routes and seasonal hours. The downtown/free trolley network typically runs daily in summer, with some routes operating year-round or on weekends and holidays, and common intervals are about every 20 to 30 minutes.

What the schedule usually looks like

  • Free downtown trolley service has been reported as running from about 10 a.m. to 6 p.m. during the summer season, with service every 20 to 30 minutes.
  • A free Navy Pier trolley has been reported as operating daily year-round from 10 a.m. until the pier closes.
  • Some trolley routes around downtown and nearby attractions have been described as running daily 10 a.m. to 6 p.m., while others are weekend/holiday seasonal routes.
  • CTA’s downtown transit pages point riders to route maps, station timetables, and trip planning tools for the most current information.

Practical note

If you mean CTA transit in downtown Chicago, the Red Line runs 24 hours through downtown, and the Brown Line runs daily with overnight service ending after midnight on weekdays and weekends. If you mean the free tourist trolley , the exact schedule depends on the route and season, so the route map or current downtown transit map is the right place to check.

Best next step

For the exact downtown trolley you want, the safest answer is to check the current downtown map and route-specific timetable, since those services can change by season and event.
