My first campaign game as the South is now in late 62. As it has always been an area of interest for me, I have been paying close attention to how the game handles Southern industrialization.
I think Civil War 2 has done an excellent job in capturing the difficulties the South had in using and maintaining their rail network.
What sort of difficulties?
To start with, the southern rail system was largely designed to connect cotton growing areas to sea ports and was not linked together in a logical pattern.
Furthermore, many of the rail companies used different gauges and trains had to be unloaded and reloaded when switching company roads.
At the start of the war, the only Southern iron works that could make locomotives was in Tennessee. It quickly fell to the North. The Tredegar works in Virginia had closed their locomotive shop a few years before the war and switched their rail machinery to other purposes.
The South did an incredible job of industrialization, but their Achilles heel was the rail net work. A limited system to began with, it was poorly managed, over worked, and quickly wore out. The transportation failure lead to food shortages in an agricultural paradise; the armies starved in the middle of plenty. In addition, raw materials could not be shipped to manufacturing centers. Proof of this is, during the war, the Tredegar Iron Works never ran at more then %70 capacity. The rich supply of Alabama and Tennessee iron never made it to Richmond.
If your interested in digging deeper into the topic of Southern war industry try reading:
Ploughshares into Swords: Frank E Vandiver - an excellent book on Josiah Gorgas and Confederate Ordnance.
Confederate Industry: Harold S Wilson - dry but informative on the textile industry.
Ironmakers to the Confederacy: Joseph R Anderson - history of the the Tredegar works.
To sum it up, I believe the game designers did an excellent job of capturing the crappy Southern rail system.
