This from Eric Haak:
Here are a few images from the CTA train derailment on August 5. The call came in from CTA who gave an approximate location of 61st and Calumet. The actual incident occurred just about directly over 63rd Street. It was a minor derailment and there were no injuries. Passengers were escorted only about 100 feet to a stairway that led from the tracks to the ground below. F634 was brought out from Midway by Engine 127 but was not needed.
