I made some Facts and Theories around the construction drawings.
I have just colored the pictures of RCTLand for some clarity:
This is known simply drawing 1, taken in 2 corners.
Well the purple line (you can see the queue) lies in the same place. As you can see in A is the purple line parallel to the station (black). So B is black parallel to the purple line. May slightly be to the left or right but it comes to the idea of the angle of the direction of the track.
Same counts at drawing A's Helix, the twist and outcome is not entirely true, but look at B you see he runs away anything from the path, hence the angle right here.
The gray (Pad) and green (Water Quay) lines are simply landmarks that you can see that I'm in the right direction.
The orange and dark red are supports footers and filled in, this helps in the 3D viewing on the helix.
Well Theory direction:
I have this picture of myself, the part of the layout drawn about because the angle is not quite correct for.
(Helix and cornering are wrong obviously, but I want to show that just fit on the area.)
Many believe the track will go from the Immlemann (which I drawn in Orange for direction and angle) straight to the Helix (featuring a cammelback and a looping) Obvious (as you can see the lines) this couldn't be true as the lift is around 2 stations (I used Krake for measuring), this would mean we go under the highest part not far beyond that. This could be the lay-out:
Station, lift, continue in the drop and tunnel, Immlemann, looping, slightly turn, Cammelback, and finish in the helix. But there may be more to it. Imagine if we go over the ground in a right turn (after the Immlemann) followed by the loop and make a Horse-Shoe turn around 2 cammelbacks into the helix. Just some wishful thinking here.
