More than a dozen cars of a freight train derailed in Blue Island Wednesday night, but no injuries were reported and police said no hazardous materials were released.

The derailment of the CSX train occurred around 9:20 p.m. at Thornton Road and 136th Street in the south suburb, according to police and the railroad.

CSX said the cause was under investigation. The National Transportation Safety Board was expected to be on the scene this morning.
