TC6 added some interactions with the rail system with arcane rails and making the bore movable by minecarts. I think this should be expanded more.

1) Vis Battery Minecarts
TC6:s aura mechanics have been described as "bland" by some individuals so I think a fitting solution for the problem of moving vis/aura would be by implementing minecarts that have a vis battery in them. It would only hold the default amount of 10 vis, but it could be moved around and controlled to your liking. It would eject all the vis into the aura when powered by a activator rail and it would toggled by the arcane rail. This addition would in my opinion be fitting to the theme and also would encourage some players to make extensive rail tracks to recharge the aura from remote chunks.

2) Flux Battery Minecarts
This would be the same as vis battery minecarts but with flux. Potentially there could be a cross mod interaction with Thaumic Wonders or you could make your own flux "battery". Moving flux somewhere else was already mentioned in other suggestions so this could be a solution.

3) Expanding upon vanilla rails and minecarts
Augmentations already adds some quality of life improvements, so I think that adding some more arcane rails and mundane rails would be a fitting addition. For examble: crossing rails, launching rails, adjustable speed rails etc. Also more minecart variants, like a thaumium cart: it would be tougher and maybe needed for moving flux, a brass cart: would be more lightweight so more speed, but cant hold any blocks like chest or furnaces, infernal engine in a minecart; an upgrade to the vanilla furnace minecart: a infernal furnace powering a minecart. It would be powered by vis in the aura or it could be charged if thats too laggy. A rail placing cart; it could have a theme of being sentient and has a brain in the cart, this would also mean a lot of control on placing the rails, where it could do twists and turns meaning it would be superior to railcrafts carts but would be more expensive and harded to use. Also minecart coupling similiar to railcraft and create would be cool, the carts would be "entangeled" by thaumaturgical means and would share resources in the storage carts.

4) Cross mod interactions (mainly railcraft)
Thaumic wonders was already mentioned, but it would be nice if the carts and rails would be compatible with railcraft, which would enable some cool automation.

Feel free to criticize and discuss in the comments.

Essentia resevoirs could be expanded with making them go into minecarts. They could be loaded with special loaders, and they would be volatile similiar to tnt carts: if they hit against something at high speeds, they will explode, making them a powerful, but hard to use essentia transport option. They would be viable option compared to mirrors for being flux free and their high capacity. The loader/emptier would be interacted by tubes and could not be interacted directly by transfusers to prevent accidents with essentia mixing.
