U have to keep in mind this is an 5 or 6 coach train. That would need a very large turntable.
Thats nothing for Vekoma
I can only think of they use the GotG CR trains that can rotate 360 degr , no need for turntable.
They can set it on random , forward or backwards. So it will be a surprise...
Here some better images from today : (Jul 17th 2022)
These are the same coaches that where on display Jul 3rd 2022, during an special event at Vekoma Factory. This train is for Energylandia. COTA train is 1 coach shorter
No, there is storage inside the factory available. (or in their storage facility)
They haven't been outside for years. last time in 2015.
They just popped up in the testing area last week.
