We had CTA and fire personnel and police actually assisting us to make sure we had nobody falling off the train," District Chief Timothy Sampey, Chicago Fire Department, said.Passengers said they heard a popping sound before the train started leaning."Just a loud pop sound went. And then the next thing I know, the train me and my kids were on, that train was leaning over," Laresa Bellamy said. "It was just a scary moment."The passengers were all checked out by paramedics at the scene. No injuries were reported.The CTA is still investigating, but it appears the third car of the four-car train derailed. The train was removed from the tracks later Wednesday evening as crews evaluate any possible track damage.
