Starting in 2006 with Thunderbird at PowerPark in Finland, the company expanded beyond the United States and began building coasters in Europe and Asia.

In 1996, the firm opened Wildcat at Hersheypark which contained many of the signature elements the firm would soon become known for: tight sweeping curves, reminiscent of designs from the turn of the century by such noted coaster designers as Fred Church and Harry Traver.

These trains also contain individual lap bars which automatically lower and lock into a position to accommodate the rider, allowing quicker dispatch times.

GCI unveiled a new train design, the Infinity Flyer, at the 2018 IAAPA Expo in Orlando, Florida.
