Technically they do race (very technical sense), but they are mirror image tracks, you never see the other train as you go along (exept in one or 2 places). So it's not a racing coaster, its just 2 tracks with identical mirror image layouts which happen to dispatch at the same time for thematic purposes (when you pass another train during the ride)
