The Big Thunder Mountain Railroad at Walt Disney World Resort is scheduled to reopen on May 3, concluding a significant refurbishment. The closure, which began in early 2025, spanned approximately 15 months, a substantial period for such a popular attraction. This extensive work has introduced new show elements, including a narrative expansion within the Rainbow Caverns. Guests will also experience updated ride vehicles.

The refurbishment involved a full track replacement and new trains, indicating a commitment to the ride's longevity and preservation of its iconic status. This strategic update balances nostalgia with modernization, a key approach for legacy attractions. Testing has been observed, with steam and geyser features being part of the ongoing activity. The reopening is part of a larger transformation of Frontierland, with construction continuing in adjacent areas.
