The ride
River King Mine Train is a steel mine train roller coaster built by Arrow Dynamics on its Mine Train platform at Six Flags St. Louis in Gateway to the West, Missouri, having opened to the public in 1971. After 55 seasons of operation it remains one of the defining attractions on the Six Flags St. Louis midway, drawing repeat riders who track every subtle change to its trains, restraints and station soundtrack.
On paper the ride is a serious thrill machine. It climbs 32 ft above the park before pitching forward into its first descent. That opening drop measures 41 ft, long enough to pin riders against their restraints and pull a prolonged moment of weightless airtime over the lap-bar. Trains reach a top speed of 37.0 mph before the first turnaround, where the layout opens up into a sequence of lateral and vertical elements. In total the track stretches 250 ft, giving the experience a distinctly long-form feel rather than the punchy one-and-done character of many modern compact coasters. enthusiast trip-planning resources
Coasters from Arrow Dynamics have a recognizable signature in track shaping, train design and the way transitions are paced. Riders familiar with other Arrow Dynamics installations will pick up on the same DNA in River King Mine Train's layout, particularly through its station design and the sound profile of the running gear. As a Mine Train, it sits within a recognizable family of attractions and benefits from years of refinement applied to similar installations elsewhere.
Plan to ride River King Mine Train early in the day or during the final hour before park close, when standby waits at Six Flags St. Louis typically drop. Single-rider lines and early-entry ticketing programs, when available at Six Flags St. Louis, are usually the fastest ways to get repeat rides on a busy day.
