Rail capacity: how to check

[Volcano Man]

Yes, I think the abstraction works well enough. What you would do, as a commander, send your large "important" combat units by rail first. Then in the second load, send your small support units up to where you dropped off the combat units. Besides, who is to say that this "rail capacity" is number of rail cars, locomotives, currently available trains (at that exact given moment), or some tonnage capacity?

I do like the fact that given that it is controlled by number of units, it can vary on the size of units that are transported at once. Do I transport 15 full strength infantry units, or do I transport 15 supply units or company sized support / gun units? Or, do I send a mix of combat and support units together for the whole organization, but in small pieces? It does make it seem a little less precise in a way, which I believe is a good thing because its not as if you would have a consistent number of trains / rail tonnage moving capacity / locomotives available at any given time. Well, that is how I justify it in my mind anyway. ;)
