The newest attraction to be themed on Snow White and the Seven Dwarfs is the Seven Dwarfs Mine Train at Disney World. It is part of the expanded Fantasyland and is a rollercoaster themed around, obviously, the diamond mine the dwarfs work in.
Only opening in 2014, I've yet to ride it, but as a massive fan of rollercoasters I look forward to putting the experience top of my list when we return to Florida in the future.
Courtesy of Youtube, it looks like a fun, not-too-intense coaster with some good dips and curves. The highlights look to be the dark ride elements. The trains pass through the diamond mine allowing riders to witness some amazing animatronic dwarves. The ride also ends by passing the dwarves' cottage where they are dancing with Snow White to The Silly Song in a set-up highly familiar from the Snow White's Scary Adventures ride. Indeed, the figures are recycled from that ride as it was closed prior to this ride being opened. The animatronic witch lurking outside the cottage window is another amazing piece of animatronic wizardry.
