If it's entirely enclosed, will the application have any details of the ride proper or just the dimensions and appearance of the building?
Best reference we'd have would be the Sub Terra application I reckon. See
Towers Street and
Towers Times for what we got then. In other words, not a lot.
Neither of those archives feature feature a particular document which showed a bit more (with some editing trickery by the sounds of it). See this
article from TT:
That gives a bit more detail to what was going on in the interior, albeit no indication about potential ride systems. However, based on that particular image, it wasn't hard for goons to piece together the most likely ride system.
I expect we'll see similar sort of details in any plans we see for this...maybe not even something as detailed as the image above. But who knows.
For a bit more reference to a 'bigger' attraction, albeit with a different council, we can look at Ghost Train's plans (see
Thorpe Park Mania). For some reason, that doesn't include the most detailed interior view that we got from the plans, but here it is:
Again, no indication whatsoever of a ride system from the plan. And in this case, much harder for goons to guess what it could be. People suggested an immersive tunnel (which I guess isn't too far from the truth), but equally quite far off. There was speculation of it even being an SFX coaster, which to be fair, from what you see there, isn't as far fetched as it sounds today imo.
tl;dr - we could end up seeing some level of indication for how the interior looks, such as big walls / rooms, which may help at least determine if an indoor coaster is likely. But that's by no means a guarantee.
