That's significant, but was it decisive? (I'm really asking, am not sure myself.) I note moving of division sized units by railway also happened during the crushing of the 1948/9 revolutions. *Lunatic*, n. One whose delusions are out of fashion.
Railroads are certainly on this list.
Nor was the importance of railroads neglected at the time. Opponent's railways, when they could not be taken over, were routinely ripped up. The Fates are kind.
After doing some read-up, I submit that railways were decisive in the American Civil War, particularly the 1864 campaigns. *Lunatic*, n. One whose delusions are out of fashion.
