Building Mag-Rails in enemy territory

[kipwheeler]

Just messing around a bit today during a war, and I decided it would be worthwhile to use a worker to make a stretch of magrail to help me move troops faster through a choke point, and a question occurred to me.

If you are at war with another faction (which lets you move workers into their territory), and if you build a magrail in his culturally-controlled space, does the mag-rail upkeep cost fall on your shoulders (since you are the builder), or on the enemy's shoulders (since it's his territory)?

I really can't tell in the current game, because I've got free upkeep on roads and mag-rail infrastructure from Supremacy 3 Affinity, so I thought I'd see if anyone here knows off the top of her head.

It does strike me that if the cost falls on the enemy when you build such a road, one goofy strategy might be to try bankrupting them (if they are non-Supremacy) by building access roads through the hinterlands of their empire.

I'm 96% sure that Magrails in Civ-Territory are paid for by the owner of the tile and Magrails in neutral Territory are paid by the person who built them.

Don't expect to "ruin" any AI above Beginner-Level though, they won't really care too much about the the maintenance from roads due to the bonuses they get.

Good point about the A.I. bonuses. Taking those into account, it would probably require pillaging every tile of the A.I.'s territory in addition to the mag-rails to dent his wallet.
