Not necessarily. As the inclined turntable is the first part of the coaster, you could either not rotate and drop backwards, or it could rotate to the right (or left, but that would take the train outside and straight back to the station). So technically there are many ways they could operate this ride. You are going forwards and backwards. The train could leave the station forwards or backwards depending on how it arrived. If they wanted, they could send you through the same section of track again, but facing the opposite direction. And if they really wanted, you could stay on this coaster all day without re-enterting the station because they are using this turtable at least twice.
The track is definitley shorter than I was expecting, but with over half of it being inside, I have hope this could be an incrediblty themed coaster. And just because it's short in track length, doesn't mean the ride necessairly will be. If there are things happening around you while you're on the inclined lift hill, the ride time could be decent.
We've got to remember this coaster is targeted for families (kids the grandparents), so it was never going to be this extreme ride, but as already mentioned by others, there are some awesome family coasters around the world and we might just be getting one.
As for the overall map of the land, it's great to see the vintage cars will have a decent track length (hopefully some aweosme themign and scenes. I'm very excited by the scale of the building that Jungle Rush will have. I was expecting there to be more pathways through the land and not just one main thoroughfair. But seeing the layout of the rides, I understand why there isn't.
I also really did think they were going to utilise the former TOT building for this land, so I hope they're planning on demolishing it because its an eyesore.
