A rail car with a possible chemical leak resulted in multiple fire departments responding to the Canadian National tracks yesterday afternoon south of Tamaroa. Crews were called to a railroad crossing on Pintail Road, south of Tamaroa, after CN railroad reported a possible chemical leak to the Perry County Sheriff’s Office.  A hazardous materials team responded to the scene and after an investigation, determined there was no leak.  Numerous agencies, including Carbondale, DuQuoin, Herrin, Marion, Metropolis and Murphysboro were staged nearby in case cleanup and evacuations became necessary.  Authorities did not find a leak so the train was allowed to continue on its route around 4 PM.  Crews did shut down Pintail Road while they investigated.  There were no evacuations and no one was hurt.
