Well, we're assuming a certain shape based on the footers and the old pre-viz's of it. What if the tower has a four-point base, as the footers indicate, but the points all converge at the top, like a Gulf oil derrick platform? I know you've already imagined that in your last but maybe it's going to be even narrower than that. Those two newest big supports are already angling to converge at a certain height. A narrow top would make curling around the outside near that height easier for the train and less speed required than if it were wrapping around a wider box shape.Did not expect the base legs of the tower to be so angled at this height... this one's gonna be weird, I can just feel it. Perhaps those join up and it becomes a 3-legged tower after all?

What really has me wondering are the two v-shaped fittings on the outside of the latest supports. The bottom two are angled about right it looks like to anchor down to the two farthest footers. Or, connect to the lower segments of the final outer supports. Then there are the top fittings of the V that would support the back tower frame laterally. And I'd guess that pattern may continue up another 100'. Beyond that, I'm really intrigued how the structure will look. The new supports will merge together in an A shape at some point, and they're pretty sharply angled already so I wonder if where they meet is near the top or shorter. If shorter, how will the rear frame be supported going up to 375'? Some real geometry and engineering lies ahead.
