DPing, but from Unagi on ParkFans: the coaster will be able to operate 4-5 trains total. I think the reason it specifies two, is because two would be on the course from the moment one clears dispatch; and then another one is cleared for dispatch when the first of the two trains hit a certain point (like say maybe a MCBR or the bottom of the dive loop booster?).
Wish
@tommyhawkins could do a breakdown of the capacity, but one has to assume this will hit near 1.4K.
