Big Thunder Mountain Railroad was designed by Imagineer Tony Baxter and ride design engineer Bill Watkins. This is a P.O.V. video of this runaway mine roller coaster. The concept came from Baxter's work on fellow Imagineer Marc Davis's concept for the Western River Expedition, a western-themed pavilion at the Magic Kingdom, designed to look like an enormous plateau and contain many rides, including a runaway mine train roller coaster.
