Disney World is in a building boom right now! With 50 magical enhancements – some bigger than others – promised before the 50th anniversary in 2021, there seem to be construction walls everywhere.

One new addition before the big date is the Tron Lightcycle Power Run, which will take riders on a thrilling race through the digital frontier.

This ride, which will be situated in Tomorrowland next door to Space Mountain, is expected to be massive. Because of its size, some attractions must be temporarily closed to allow for safe construction for both workers and guests.

At this point, we only know of two, but there could be more before Tron is completed. Let’s take a look at what we know about the two planned closures.

Walt Disney World Railroad

The Walt Disney World Railroad circles the entire park with stops in Frontierland and Fantasyland before returning to its home station on Main Street USA.

The railroad, which passes by Tomorrowland, will be entirely shut down because the Tron construction will interfere with the railroad’s track. The closure begins December 3rd, and Disney hasn’t given a reopening date leading many to believe that it will be well into 2019.

However, the closure means a really cool photo opportunity with the train that normally doesn’t stop for photos. You can even get an up-close look at the train, which isn’t possible during regular service.

Walt Disney World Railroad is expected to reopen exactly as it currently is with no changes to the current track.

Two popular Magic Kingdom attractions will have to close temporarily to make room for Tron.

Tomorrowland Speedway

Tomorrowland Speedway won’t fare as well.

The gasoline-powered auto attraction, while far from futuristic, is located in Tomorrowland and is still very popular – especially with smaller drivers. When Disney announced that Tron would be coming to the park, many thought that this meant the end for one of Walt’s favorite rides.

While the track will have to be modified to make room for Tron, the attraction will reopen on May 18th, 2019.

Fortunately, it will remain open for the 2018 holiday season with the closure not starting until January 2nd.
