Comet has a 'double out and back' layout. These two turns reverse the train's direction to send it back toward the station. The second turn, shown with the blue train at the bottom, is just insane. The train goes unbelievably fast at that point, and the track has little banking, so the lateral g-forces are extreme. Riding it in the dark makes it even crazier!
