Sure, I could see I was not getting my point across.
As to vertical track, you might be able to build a 2 mile near vertical track but you end up adding a lot of energy more cheaply with a horizontal track and for the most part it's energy that's important as you can trade horizontal energy for vertical energy inside the atmosphere. Don't forget for moderate cost you could use balloons to get a few tons to 50+km up where the air is vary thin. But altitude is just not that much of an issue.
