The Fantasyland section of the Magic Kingdom underwent a large expansion and renovation from March 2010 through May 2014.
As part of the expansion, the Magic Kingdom's original Snow White attraction, Snow White's Scary Adventures, was permanently closed on May 31, 2012 and replaced with Princess Fairytale Hall, a new Disney Princess meet and greet. A new area themed to Snow White and the Seven Dwarfs, featuring Snow White's cottage and the new the Seven Dwarfs Mine Train roller coaster, was dedicated on May 2, 2014 and officially opened on May 28, 2014.
The ride soft-opened in the Magic Kingdom on May 21, 2014, fully opening a week later on May 28, 2014.
The queue hosts a few interactive activities. One is a gem-sorting game where you match up three jewels of different shape but the same color. There is also a spot with barrels full of gems that you spin to create reflective animations of the Seven Dwarfs on the ceiling. If all of the dwarfs are present on the ceiling, an animation of She pictures in.
On November 1, 2014, falling embers from Wishes fireworks show landed on the fake grass exterior of the ride, causing a fire near the bridge that the coaster travels on just before entering the mine. This caused the ride and the area around it to be evacuated. The fire was first reported around 10:20p.m. Reedy Creek Fire Department responded and extinguished the fire within minutes, according to eyewitnesses. By 11 p.m., multiple eyewitnesses said the fire was out. There were no injuries reported. The area around it reopened later that night and the ride reopened at 12:30 a.m. that same night.
