Disney have added a backstory to Big Thunder Mountain Railroad, the popular rollercoaster attraction at the Magic Kingdom.
From the official Disney Parks Blog:
Barnabas T. Bullion is the founder and president of the Big Thunder Mining Company. The longtime mining magnate comes from a powerful East Coast family and considers gold to be his very birthright by virtue of his oddly appropriate name; in fact, he considers the ultimate gold strike to be his destiny. And that is why he is having so much trouble with Big Thunder Mountain. According to superstitious locals, Big Thunder Mountain is very protective of the gold it holds within, and the unfortunate soul who attempts to mine its riches is destined to fail. And so far that prophecy is coming to pass. The mine has been plagued by mysterious forces and natural disasters ever since. And yet the Big Thunder Mining Co. is still in operation. In fact, Bullion is discovering new veins of gold and digging new shafts every day, offering a closer look at the Big Thunder mining operation than ever before. But a word to the wise for anyone attempting to visit the mountain: watch out for runaway trains.
Disney have confirmed that a number of new additions, including interactive elements will be added to Big Thunder Mountain Railroad as part of this new backstory. Work on the queue area has already begun overnight, two new additions include a portrate of the Barnabas T. Bullion character, and a landscape of the mountain itself.
