The Union had more than twice the density of railroads per square mile as the Confederacy, and several times the mileage of canals and macadamized roads. The South could produce enough food to feed itself, but the transport network, adequate at the beginning of the war to distribute this food, soon began to deteriorate because of a lack of replacement capacity. Nearly all of the rails had come from the North or from Britain; of 470 locomotives built in the United States during 1860, only nineteen had been made in the South.
