Busch Gardens Tampa has confirmed that when Gwazi reopens after a brief rehab on January 22nd it will be debuting new Millennium Flyer trains from Great Coasters International. The dueling wooden roller coasters opened in 1999 and feature over 7,000 feet of track combined.
The new trains will invigorate the coasters with a much smoother experience, which the general public and enthusiasts alike are sure to enjoy. To celebrate, the park will give each Gwazi rider on Januray 22nd a coupon for 30% off any restaurant or snack cart in the park.
Inside the Magic has posted some photos the park released of the new trains already on the track. I believe this change leaves Roar at Six Flags America as the only GCI with PTC trains.
