Miles of railroad in the United States prior to the American Civil War 1861

This graph shows the total length of railroad tracks in each of the home fronts in 1861, at the outbreak of the American Civil War. From the data we can see that the Union States had over double the amount of railroad than the Confederacy, and well over ten time that of the Border states. This is was a significant advantage for the Union forces as they had a much better infrastructure for transporting men and supplies throughout the war.
