As you point out a circle helix will not provide enough clearance. Using
Matt's rule of 2/3 brick rise per section of track a circle of 16 track
sections has a maximum clearance of 10 2/3 bricks - track height (1 brick) and
roadbed/support thickness (1 brick) = 8 2/3 bricks. My tallest train (measured
from the top of the rails) is ~12 bricks. As you say, no go. However, if you
add 10 straight sections to the circle to make an oval of 26 sections you get a
clearance of 17 1/3 bricks - 2 bricks (see above) = 15 1/3 bricks. Of course
all this is theory at this point. Most of my locos have 2 drive motors each
anticipating the need for pulling pow
