1916 Explosion at Miller, South Dakota Roundhouse

I found this postcard with papers previously belonging to my step-great-grandmother, Ida Marie Sherman who married Charles Lorenzo Vandervort (and became step-mother to his three children)and a decade after he passed away she married John William Radloff.  Charles Lorenzo Vandervort worked for the railroad as an Assistant Master Mechanic.  He worked for the Milwaukee/St. Paul Railroad in Milwaukee from 1890 to 1901.  He worked for the Soo Line in Enderline N Dakota, Gladstone and Minneapolois from 1901 to Nov 1922.  He died in  1 941.  He worked for the Rail road for a total of 31 years according to his wife's notes. He and Ida likely had this postcard since they lived in North Dakota at that time.
