two belts on one tile width

You can also carry 100's of factories around in your pocket. I don't find it too much of a stretch to imagine that there is more going on below the surface than meets the eye. Perhaps each tile is a 20m square, and it's just the icon that fills the view. Just seems an arbitrary thing to get "it can't work that way" about.

Yeah, I try not to think about the stack of trains in my backpack.

Theory as to why it works, and why they are at different depths for different belts. Each belt is moving at different speeds, So in the same amount of distance (The single Map tile in which the change elevation) the faster belt could cover more "Ground" in the vertical direction. Not to mention with the resource cost of setting something like this up, can you really call it an exploit or unrealistic? There is no reason why an underground belt would only be able to travel so far without resurfacing its all just balance and in my opinion the cost of doing this, is the balance.
