Plans reportedly showing the layout for Mickey and Minnie’s Runaway Railway have been posted online by a Twitter account infamous among Disney fans.

The account, known as BackDoorDisney, has gained notoriety over the past year for posting photos from backstage areas of Walt Disney World off-limits to guests, as well as the original account owner’s connection to unproven rumors that an animatronic figure had been stolen from Epcot.

The account said the plans were posted elsewhere online, but neither Orlando Rising nor other theme park sites have found the original source for these purported blueprints.

If the plans are legitimate, they depict how Mickey and Minnie’s Runaway Railway will utilize the existing show building left from its predecessor, the Great Movie Ride. Beginning at the same loading platform as the shuttered ride, the new attraction would take guests through scenes with names such as “Trouble in the Tunnel,” “Hover the Falls,” and “Picnic in the Park” — the latter of which is similar to “Perfect Picnic,” the new “Mickey Mouse” short cartoon being developed for the ride.

The blueprints begin with numbering Scene 3 (the vehicle load area), indicating the ride’s queue will contain two more scenes setting up the attraction’s premise.

The attraction appears to largely follow the same track as the Great Movie Ride, though the new ride will use a trackless system that allows the vehicles some additional freedom. According to the blueprints, the vehicles (or “train cars”) will be connected when guests board the ride, but that connection will be lost somewhere between “Trouble in the Tunnel” (listed as Scene 5a in the plans) and “Stampede” (Scene 5b).

Disney has not commented on the validity of the blueprints.

Mickey and Minnie’s Runaway Railway is still under construction. Originally set to open this year, it’s now been delayed to spring 2020, leaving Disney’s Hollywood Studios without another high-capacity addition as crowds are drawn to the park for Star Wars: Galaxy’s Edge.
