We're just using Raptor as a basis considering it's the only other ride that we can gain an understanding on for how Swarm will work. You hit that top break on Raptor (yes, the one after the slow inline) and then stop. On every other B&M I've ridden, the train always stops outside the station ready to come in when the train in the station has left. For some reason this doesn't happen on Raptor. Instead the train moves from the top break area, into the bottom at quite a speed, you stop briefly again and then move into the station. This as you can imagine wastes quite a bit of time as by the time you reach the station, the other train has already left the lift hill.Now whether Swarm will work like that considering it seems to have three break areas remains to be seen. Just at the moment, that part of track layout looks very similar to Raptor.As for trims, Superman de Acero and Raptor are notable ones I've ridden where they remain on. They are both excellent though, regardless so it shouldn't effect Swarm's effect hugely.
