From the July 26, 2017, MidWeek (DeKalb County, Illinois) "Looking Back."
1917, 100 years Ago.
"Yesterday forenoon a long freight train rolled through DeKalb (imagine a train going through DeKalb) and an acid car near the middle of the train was seen to be steaming rather alarmingly. Officer Rowe spied the matter and telegraphed to the railroad headquarters concerning the matter.
"The train dispatcher stopped the train in Maple Park (about ten miles away) and the car was given attention. Railroad men of the local yards say that this is the first time they have experienced such a thing as that."
Could Have been a Major Problem. --RoadDog
