Note: Why the “Rails to Oblivion” post title? Because the lack of an efficient system of railroads is one of the six main reasons why the South lost the Civil War:
1. Weak federal government.
2. Lack of manufacturing capacity.

4. Tiny navy / little shipbuilding / ship repair capacity.
5. Unable to arm the largest Southern pool of potential soldiers:
male slaves ages 18-50 years old.
6. Poor coordination of the efforts of Southern armies.
