The Seven Dwarfs Mine Train roller coaster forms part of a major expansion of the Magic Kingdom's Fantasyland that was completed in 2014.
The coaster takes guests on a musical ride deep into a diamond mine. It features a first-of-its-kind ride system that allows the vehicles to swing back and forth as they move along the twisting track, accompanied by tunes from "Snow White and the Seven Dwarfs".
The Seven Dwarfs Mine Train was manufactured by Vekoma (a favorite of Disney, responsible for nearly all of its modern steel roller coaster work) and features both indoor and outdoor sections. The ride sits somewhere between Barnstormer and Big Thunder Mountain in terms of thrills.
