The main East - West lines for the Union Pacific railroad runs right through Iowa. Along these tracks have been many, many tons of coal, new automobiles and even the two 200 inch blanks for the Mount Palomar Hale telescope direct from the Corning Glass Works in Corning, New York. Yes, two blanks. The first one delivered developed a crack in the lens and needed to be replaced. It is or was on display at Corning's museum.
