CTA Blue Line derails at Pulaski on Forest Park branch

CHICAGO (WLS) -- CTA Blue Line trains are running again with residual delays after a derailment near Pulaski on the Forest Park branch.

Service was restored between Cicero and Western on the Forest Park branch around 9:15 a.m., about two hours after the derailment.

"I feel like we ran over a giant object or something, like some cylinder or something. That's all. I saw some smoke come up. I thought the engine broke, because I don't really know how trains work. I thought an engine popped or something," Isaiah Hinton, passenger, said.

"I heard a small crunch sound, then I heard a poof of smoke. A plume of smoke, and the train stopped," Alex Moore, passenger, said.

No one was injured, Chicago fire officials said, but they had to help one woman off the derailed train in a stretcher due to another previous leg injury.

"There was a part of the train that came off, which derailed one wheel on the second car, right. We shut the power down on both sides of the train for safety," Chicago Fire Department Commander Jeffrey Horan said.

Those on the derailed car were escorted off the tracks by firefighters. Passengers in the other cars stayed onboard while crews separated the derailed car and moved the rest of the train back to the platform. The train only had to back up about 600 yards, CFD crews said, since it had just pulled out of the station.

Officials have not determined if the weather led to the derailment, which remains under investigation.
