RE: The Startram Project: Shoot a Train Into Space
What kind of forces would be exerted on the "train" upon exiting the vacuum tube? I imagine it would be a pretty intense deceleration?

The tube ends at a height of 12 miles, that is so the atmospheric pressure is reduced enough to allow it to still reach space even though some deceleration would happen once it did leave the tube. By my calculations that altitude has only 6.8% of the pressure at sea level.
So leaving the tube would be like hitting a wall in a car that was traveling 2.7mph - not so bad.
