Wow, great scenario! I just won as the South, and thought I'd share how I did it. First of all, if you don't find any iron, you're screwed, because you have to rely on the weapons and ammo coming from the Wilmington port which is not NEARLY enough. I exclusively searched in Alabama for iron with success almost every time. Montgomery is an excellent place to produce your weapons and ammo as it is right down river from your iron mines (all of them you should own). Before the barracks start popping up, I was making bank sending weapons and ammo from Montgomery down to Mobile and then on to New Orleans (double track). This made it fairly easy to save Louisiana in 1862 with four trains running. As 1862 drew to a close, I built a double track straight shot from Montgomery through Meridian to Jackson (where the barracks is). Before the year was up, I redirected my weapons/ammo trains to carry to Jackson instead of New Orleans (after I met the quota). Just in time, since the value of weapons and ammo in Montgomery starts to equal that of New Orleans, and your trains won't haul those goods anymore. The next year, do the same thing, except route your four trains to Atlanta instead. Also, have a train prepared to run from Wilmington to Atlanta right at the start of the year, as that distance takes awhile. Since Montgomery is pretty close to Atlanta, that one is the easiest.
One suggestion. It would be fun to be more specific with the troops, i.e. (send enough troops to Richmond for Lee's northern invasion of 1963, or to Atlanta to defend against Sherman's march, Grant in Vicksburg, etc.)
Great Fun!
