Need a different bogey, or clone and edit that bogey to raise it up. Simplest way to do that is add a position tag under the main mesh for the bogey, start with 0,0,0.1 and see what it looks like in game. What I use to approximate is 1 meter = 40 inches, so 0.1 is 4 inches, 0.025 is one inch. Adjust and repeat until the little beggar is sitting with the wheels on the rails.
