About 2,500 ComEd customers had their night interrupted when eight cars on a CSX train derailed, one of which slid down an embankment at struck the power pole.
No one was injured in the derailment, which occurred around 2 a.m. CDT in the city's Ashburn neighborhood, the fire department said. The mishap involved one train that struck the other in the rear. A third train on an adjacent track was also damaged, the Chicago Tribune said.
Fire spokesman Larry Langford said at least one of the cars was hauling some type of liquid waste but there were no leaks detected.
A CSX spokesman told the Chicago Sun-Times an investigation was under way.
