For over 50 years this roller caster in Missouri has been taking riders on an extreme, intense ride, and it's gearing up for another season.

The River King Mine Train at Six Flags St. Louis has been around since 1971 and at first, had side-by-side tracks. One of the tracks was sold to the Dollywood theme park where it was in operation from 1989-1998.  It was then moved to the Magic Springs in Hot Springs, Arkansas, but the Six Flags mine train is still in operation today.

The ride reaches up to 37 miles per hour while moving through a series of dips, dives, and turns. I am not a big coaster rider, but every time we visit Six Flags this is one coaster that I can enjoy even with that 14-foot drop in the dark.

The whole ride is 2349 feet long, reaches a height of 32 feet, and is one of the coasters that if you want to introduce to your kids might be a good start and not some BIG like the Ninja, or MR. FREEZE,

The coaster is registered on the National Register of Historic Places and is a historical landmark. Now, it's not a super fast coaster with speeds going up to 10 miles per hour, but it holds so much history on where coasters started and how they are designed today.
