Okay, so I know other servers that advance pretty far end up getting a subway. I think it would also be nice to get to other sides of the island quicker, but underground or in the air to avoid disturbing other buildings.
I think the only problem with a subway, though, is that it would collide with the mines at some point.

Perhaps the subway could start in the mines? That way it wouldn't collide with them as such.
