I'm going with Rita retheme - they're flogging of Rita merchandise cheap
Other than that, the supports and track match - 100% - supports and track for Premier and Mack eMotion coasters. As much as they can do doing direct comparisons based on the plans. It's very regular, very basic supports (due to the bi-rail track not having much support in itself).
Obviously, we'll not know until actual track arrives if it's identical to the plans, but if it's different, the council will have a fit. Where they say footers are going, and the size of them - they have to match the plans.
Vekoma bi-rail track is VERY different to the track in the plans. So it was always a long shot it was going to be Vekoma.
I don't think manufacturer is important anyway - it's the "world's first" bit which really makes the ride. We already know the basic layout pretty much sucks!
