Rail capacity gyrating wildly

[CapAndGown]

Last turn my reserved rail capacity was 32k. This turn it is 19k. I didn't lose any rail yards. I don't have anybody still entrained at the end of the turn. The front has barely changed. Yet my rail capacity is gyrating wildly up and down. How am I supposed to be able to plan anything if I can't at least have a rough idea of what my troop transport capacity will be one turn from now? What gives?

Hard to say without more info but haven't seen that happen myself. Would need to see the event log information. Usually the culprit is having units still entrained but looks like you checked that already.

Weather changes and rebasing or overusing aircraft can strain transport of supplies.

I don't see how that can change my rail capacity. I might not have enough rail capacity to move supplies, but the capacity should stay the same, meaning my reserved rail capacity should remain the same. Its not like if I move lots of troops one turn the number I can move next turn should go down.

In bad weather, the rail modifier decrease means that less rail is utilized and therefore there is less demand.

Also, units on rail at the beginning of the turn subtract their rail points from the total capacity. And then AFTER that the reserve rail % is calculated out. Probably an oversight, but it is what it is.

Not sure how these might play into your exact situation but they definitely can matter.
