SALEM, IL — Salem fire crews responded to two incidents on Wednesday. Firefighters were called to a car fire on Hawthorn Road after the exhaust system ignited dry grass while a car was attempting to pull a mower out of the mud. Crews quickly contained the fire. Later, they responded to a transformer explosion on South Maple, which caused a brief power outage and a small fire. The flames had already been extinguished by the time firemen arrived, and they remained on scene until Ameren crews took over.
