I apologize for the delay in replying to your comments - I hadn't realized I had left these unanswered.
Pocus, the pics are straight off of Google, though I believe what I titled the Montgomery ironworks is actually a picture of a mill in England at about the same time. I'll be glad to send you copies of the pics if you PM me an address (or tell me to use the company address). I do have some pics of Alabama ironworks.
Historically, Alabama produced a lot of pig iron from the Tannehill region, and Mobile was an important iron-works town (a lot of the decorative iron railings that New Orleans is famous for were actually made here in Mobile). During the Civil War there wasn't enough manpower or transportation to make use of the deposits, but post-war Birmingham, Alabama became a huge iron and steel producing city. In my story my tycoon forces the development of the iron industry 30-40 years earlier than it actually happened.
I created an American Civil War scenario for Railroad Tycoon 3. Basically you have 20 years to build a railroad and five years of war to put it to the test. Each year of war has a hauling mission, carrying ammunition and weapons to Kentucky or Missouri (1861), Tennessee or Louisiana (1862), Mississippi (1863) and Georgia (1864). Virginia, North Carolina, Tennessee, Kentucky, Missouri and Arkansas may - or may not - join the Confederacy. If at least 5 states remain in the CSA in January of 1865, Lincoln fails re-election and the South wins. You can play as the North, or the South.
The basic plot for the AAR hinges on a few points. One, I assume that an excellent railroad net (coupled with intensive industrialization as the railroad builds the industries to make goods it can haul and sell) enables the South to use an over-sized army corps as a 'fire-brigade' to turn back Union invasions of the West. Two, I make Jeff Davis' health a bit worse than in 'our' history, putting Robert Barnwell Rhett in the Presidency. Rhett may have been one of the very few men who could alienate and insult people faster than Davis. Third, I assume the eventual Confederate victory is hollow - the revolution collapses as the Southern fire-eaters turn in on each other and rip the CSA apart. High war debt, manpower losses, the expense of maintaining a standing army and navy and above all the inability to deal with post-war political realities simply sink the post-war South.
The battles and such in the AAR are descriptions of what was happening in the AAR but the plot elements are all my own imagination.
veji1, thank you for the compliment, and for taking the time to let me know you liked it. There are other AARs of mine
here. The link is to a Napoleonic AAR, but my latest one is Frontier, for Galactic Civilizations II. Look in my signature for the links.
Jabberwock, I hope you enjoyed the AAR. Certainly you should spend more time playing AACW and perhaps writing your own AAR for it.

It looks like AGEOD has covered the elements I think essential, and handled them in ways I find appropriate and useful. Now that I have improved my graphics card I hope to take on the game myself sometime soon.
