River King Mine Train

River King Mine Train is a steel coaster at Six Flags St. Louis that features about 2349 feet of track with multiple chain lift hills. The ride includes a tunnel section and carries 30 riders per train across five cars.

The ride opened with the park in 1971 and has been a fixture of the amusement park ever since. A 1984 renovation introduced temporary changes to train design before the attraction returned to its original setup.

The name references a coal mine that once operated in the region, connecting riders to the area's mining heritage. This link to local industrial history adds context to the mining-themed setting of the attraction.

The ride reaches speeds around 37 mph and features a drop of about 41 feet with predictable high points. Allow time before boarding to understand the safety setup, which requires staff to operate manually.

What sets this coaster apart is that safety bars do not close automatically but are manually operated by staff for each rider. This uncommon system makes the ride feel distinctly different from modern automated attractions.
