A new aerial photos of the new Potter coaster posted to Twitter this weekend shows a train on the tracks, with the cars wrapped tightly in white plastic. While you canít see the details, the trains are seven cars long, and if the Motocycle theme is true, and the shape does look a bit abnormal, then the cars will seat two across, so only 14 riders per train, compared to the 32 riders that fit in a Hulk coaster train, or the 24 that fit in the Gringotts trains.
