I stopped by WDW's Magic Kingdom yesterday to check out some new theming that's recently been installed in the standby queue of Big Thunder Mountain Railroad.
These new additions are rumored to be part of yet-unannounced interactive features expected to appear in the attraction later this year, similar to earlier enhancements in Space Mountain and Haunted Mansion. Currently, the interactive features have not been enabled, but we can get a hint of how they may work from what's already been installed.
To begin, there are a number of signs and set pieces themed around the "Big Thunder Mining Company" offices.
There's gold in them thar safe!
Some humorous signs depicting the "glamorous" life of Old West miners.
Next, we enter the explosives storage area.
This overhead electronic device may trigger an explosive effect...
Along the windows closest to the ride track, these hand-cranks and plunger boxes have been installed. Perhaps guests will be able to trigger "explosions" as trains pass through the finale.
Then there are a series of devices that appear to be periscopes for peering down into the mine shafts below.
...followed by these boxes with circular cranks. No clue what they may do.
Note the canary cages hanging from the ceiling. Never go down into a mine without one!
Finally, these machines seem to spray samples of air from various depths.
