Overview
- Big Thunder Mountain Railroad returned with a fully replaced track and new trains that produce a noticeably smoother ride.
- The attraction’s story now centers on mining magnate Barnabas T. Bullion, with expanded scenes that include Rainbow Caverns and a gold mine finale.
- A lowered 38-inch height requirement was reported for the reopened coaster, allowing more young guests to ride.
- Magic Kingdom’s May 2026 paper guidemap marks the ride with a purple “REFRESHED!” label to call out the update.
- A new side-by-side POV shows a brighter Rainbow Caverns and a shimmering gold-filled third lift in place of the former falling-boulders sequence.
