That you tube video is fake.It was made by a 14yr old who obviously cannot spell
It isnt made by a 14 year old. Ollie from coaster force knows the uploader, the uploader isnt who made the video. Also, I dont see any spelling mistakes. =/
This has been considered before in detail, the main argument against being the distinctive pieces of V shaped attachment to the ends of the track before the area was enclosed. These, whatever they are (and it's mooted that they are the means by which the track disconnects/attaches) obviously serve the same purpose on each level, and therefore cast extreme doubt on there having been a track extension on the lower level.
This theory relies on the fact that the moving section will not only move up and down but forwards and backwards, and given the size of the building and the limitations as to how much it can move forwards and backwards, it would be extremely impractical for them to gear the technology for such a small movement (The offset distance) when they can make it do a simple up, down motion as is shown in the video.
