Hear me out here. I believe I've narrowed down the track type, at least.
The distance of rail to spine is too close together for the track to be a Hyper/Mega.
Dive machine is completely out. No more speculation for a Dive Machine should be discussed. The ties are COMPLETELY different.
It is also not any style of "inverted" coaster, as indicated by the rail ties. The inverted styles such as the classic B&M Inverted and the Flyer have curved ties, and the Mystery Track has straight ties. NOT a Flyer or Inverted.
Which leaves either Sit Down, Floorless, or Stand Up.
The center of the ties are very small. All three styles remaining have small center ties. However, the distance from rail to spine is slightly longer in Floorless and Stand Up than in Sit Down, and as much as I would love to see a Stand Up built, I feel as though this is a Sit Down style coaster.
Just my two cents. However I could be terribly wrong with my conclusion based on the angle the photo was taken. (Please excuse my large post.)
