CTA Tracker Apps Go Dark April 22 for Maintenance
Chicago transit riders won't be able to check real-time bus and train arrivals starting Wednesday, April 22, 2026, at 10 p.m. when the CTA takes its Bus Tracker and Train Tracker systems offline for planned maintenance. The outage affects all CTA routes systemwide, though transit officials said actual bus and train service will continue operating normally during the work. Officials didn't specify when the tracking systems will come back online.
Tracking Systems Offline, Service Continues
The maintenance work targets only the digital tracking infrastructure that powers real-time arrival predictions, according to the transit agency. Route schedules and the trip planner tool will remain available for departure information during the outage, officials said. Transit agencies typically perform such maintenance during off-peak hours to minimize rider impact, though the CTA hasn't said whether this work will extend into Thursday morning's rush hour. The agency advised customers to use alternative methods for schedule information during the maintenance period.
Systemwide Alert Covers All Routes
The alert applies to the CTA's entire network, including all bus routes numbered from route 2 through route 192, officials confirmed. Multiple rail lines are currently operating with various service statuses, including normal service and planned work. Elevator alerts are also in effect at various stations across Red, Brown, Green, and Orange Lines, though officials didn't specify whether those are related to the tracking system maintenance. The agency said passengers should check the alerts page for any unplanned or planned service reroutes during the maintenance window.
No Timeline for System Restoration
Officials scheduled the maintenance to begin at 10 p.m. Wednesday but didn't provide an end time for the work. The CTA hasn't said whether the tracking systems will be restored by Thursday morning or if the outage could extend into the workday commute. Transit agencies typically complete such maintenance within several hours, though complex system upgrades can take longer.
Riders Face Temporary Information Gap
Commuters who rely on real-time arrival predictions will need to consult printed schedules or the trip planner tool during the maintenance period. The outage affects both the Bus Tracker and Train Tracker systems that thousands of riders use daily to time their trips. Moovit provides real-time CTA updates and trip planning for Chicago transit riders, with alerts about service changes and arrival predictions across the system.
