The blueprint info is correct. I took 2 blueprint classes in college almost 20yrs ago plus work for a company that stores blueprints of everything they build. There is never just 1 blueprint... it would be too much info on the image.
Onto the layout-
Since we cant deduce altitude fluctuations yet, what if the track length is much larger than anyone though as the layout is more vertical than expected... or more vertical than any other giga?
I've been crossing my fingers for a long time that this giga hinting at outpost 5 would include the worlds first hyper loop... and first loop ever on a giga. Imo, it takes a strong bold move to reference outpost 5 if you have no plan on making a steel coaster to produce records that probably will not ever be broken for LONG time financially. If SoB still existed, it would still be untouchable...
