Re: Alton Towers | The Smiler | Unknown Gerstlauer World's 1
Here's the same area in the plans showing both hills:
I think that makes it easier to compare the image you've posted and the proposed layout. Your "inversion" support would be on the far left of those plans I think - the hill kind of peeping through the trees.
I did hear that the ride was meant to have 13 inversions, so it's always possible there is another one here, and either one hidden like Saw in the secret area - or a multiple roll taking the inversion count up.
Seeing the drop between the station height and the lift hill, would it be possible for the track to spin tumble drier style as it drops vertically down?
