EMPLOYEE #1 CLIMBED THE EMBANKMENT TO THE RAILROAD TRACK ABOUT 1000 FEET NORTH OF LAKE COOK ROAD. HE WANTED TO GIVE INSTRUCTIONS TO SOME EMPLOYEES WORKING ON THE EAST SIDE OF THE RAILROAD TRACK. WHILE STANDING ON OR NEAR THE RAILROAD TRACK, EMPLOYEE #1 WAS STRUCK BY A NORTH BOUND SOO LINE FREIGHT TRAIN (A SINGLE ENGINE AND A SINGLE BOX CAR). EMPLOYEE #1 RECEIVED MULTIPLE INJURIES, AND WAS PRONOUNCED DEAD AT THE SCENE BY THE LAKE COUNTY DEPUTY CORONER. THE TIME OF DEATH WAS 11:47 AM ON JANUARY 17, 1986.
