Red Line Derailment: CTA Train Derails Near Armitage, Causes Widespread Delays

Updated story

A train on Chicago's CTA Red Line derailed late Thursday morning, causing widespread delays and service interruptions.

According to the Chicago Tribune, the derailment took place around 11:20 a.m. when a southbound Red Line train left the tracks near Armitage Avenue, causing the power to be shut off on both the southbound Red and Brown lines and the northbound Red Line.

By late Thursday afternoon, ABC Chicago reports, service was restored on both the Red and Brown lines. Prior to that, commuters had to rely on shuttle buses and other alternative means of transportation:

Sixty-four passengers on the train were moved off the derailed car into another train car that had been pulled alongside of it, NBC Chicago reports.

Two DePaul University students told CBS Chicago it took about 45 minutes for all passengers in the derailed car to be moved off the train. No injuries have been reported though one woman was taken away on a stretcher because she was reportedly "shaken up" by the incident.

A witness walking less than 100 yards from the derailment told DNAinfo Chicago he "just heard a big boom sound, and then just a huge screech and everyone screaming."

The incident made for huge crowds pouring out into the streets at nearby rail stations, particularly at Belmont, as documented by Lakeview Patch editor Andy Ambrosius:

The CTA has yet to determine what caused the derailment.
