It looks like Big Thunder Mountain Railroad won’t have the promised “exploding dynamite” when it reopens in 2026.
Big Thunder Mountain Railroad Description Update

A few days ago, Disney shared more details of the updates coming to Big Thunder Mountain Railroad at Magic Kingdom. The ride closed this past January and will reopen next year “with a little bit of new magic.”
Big Thunder Mountain Railroad Refurbishment Update Removes Mention of Exploding Finale
A new description of Big Thunder Mountain Railroad on the Walt Disney World website stated guests would “dodge exploding dynamite and falling boulders as you swoop around turns, drop into canyons, and dart through the town of Tumbleweed.”

The references to exploding dynamite and falling boulders have been removed from the website. Here’s the updated description.
The story of Big Thunder Mountain Railroad begins when Barnabas T. Bullion struck gold in the Big Thunder region. One day, strange and unexplainable things started happening. No matter how deep the miners dug into the heart of the mountain, the forces of Big Thunder fought back.
After you arrive at the legendary Big Thunder Mining Company, descend into an active mine shaft and board your runaway train. As you enter the cavern, the engine speeds up along the rickety track, then swoop around turns, drop into canyons and dart through the town of Tumbleweed.
The dynamite seemed to indicate the Magic Kingdom version would get a scene similar to the Disneyland version of Big Thunder. In 2012, the California coaster got an update including dynamite exploding in a simulated earthquake effect around the train as they climb the final lift hill.
The rest of the Big Thunder Mountain Railroad description remains the same, including the new Rainbow Caverns opening scene.
