but why do they slow movement? If they're underground, the surface could be bulldozed to speed units up...

Wow, tubes slow movement. :blink: You learn something new every day.
I have no clue why that might happen... I wonder if it is intentional or not?
Anyway, I think the programmers kind of "cheated" in making tubes indestructible for the sake of simplicity.
I imagine the reason that train tracks couldn't be made similarly invincible is that they have too big a strategic value, and are such a big factor in war that it would be stupid to make the enemy unable to affect them.
I personally would love to see some implementation of monorails/trains/etc. just out of sheer curiosity, but most of the community seems opposed to the idea, so, whatever...
