Apocalypse The Ride
Every GCI coaster, with just one exception, now operates with GCI-designed Millennium Flyer trains.   Roar at Six Flags America is the outlier that still uses PTC trains.  The articulated Millennium Flyer trains, which can be identified by the open gate on the front car, have short two-passenger cars.  This design allows the trains to go through tight twists and turns.
