Early as I said before the railroads generally interchanged freight cars Maybe back to the 1850s when several railroads provided the possibility of a through route between the east coast and Chicago. And then continuing for another two or three decades. A few years ago I read about this era -- maybe in the R&LHS publication
Railroad History. Or maybe in the book
The American Railroad Network, 1861-1890 from the University of Illinois Press.
