A Red Line train approaching Granville "took the wrong route" early Monday afternoon and ended up straddling two set of rails, says a Tribune report. The CTA corrected their own original assessment of a derailment in the incident in which no passengers were injured.
Before it all was over, the Chicago Fire Department sent five ambulances to the scene, thinking a derailment had occurred. But the CTA was able to uncouple the rear car and move the rest of the train back to Loyola station, where passengers exited safely.
Service between Howard and Belmont was suspended soon after the incident occurred at about 12:45 p.m. The CTA was able to restore full service by 2:30.
In April of 2011, a similar incident occurred on the Brown Line, with the CTA insisting it wasn't a "derailment" because "all of the wheels stayed on the track."
