I’ve found a theory on Twitter from JAMMY that could possibly explain why John Wardley is “impressed” with the capacity of the new coaster while also keeping to what we know about it only having one train and excluding any theories about 2 trains and fancy station setups:
Basically, JAMMY’s suggestion is back to back winged seating similar to what the Vekoma Invertigo has. This would double the capacity per train from 24 to 48, and would result in 4 riders per row per side rather than 2. It would also suit a shuttle coaster; as I said above, this has been done before on the Vekoma Invertigo models.
In theory, this would effectively double the theoretical capacity from 720pph to 1,440pph, but it should be noted that the park time would be roughly twice as long (2 minutes rather than 1 minute) with a 48-rider train compared to a 24-rider train. However, this would still boost the capacity to 960pph, or a 48 rider train every 3 minutes, which is fairly decent.
