Engineering the Matterhorn Bobsled Ride: A Walt Disney Engineer's Story

The Genesis of the Matterhorn Ride

• 💡 Walt Disney's inspiration for the Matterhorn Bobsled ride came from a postcard of the Matterhorn mountain in Switzerland, which he wanted replicated.
• 🎯 Walt tasked engineer Bob Gurr with a seemingly impossible assignment: to "put a track inside this mountain," giving him only nine months.

Overcoming Design and Material Challenges

• 🛠️ The team faced a significant timeframe problem, leading them to innovate by using tubular steel for the coaster track, a novel approach for such an application.
• ⚠️ Concerns about the hollow tubes sustaining the weight were addressed by pressurizing sections of pipe with air and monitoring for leaks.
• 📐 Bob Gurr, despite admitting to an F in geometry, designed the complex three-dimensional track using pencil, paper, and a compass, thinking in "slices" to translate 2D drawings into a 3D ride.

Testing and Legacy of the Ride

• 🧪 During the initial test run, hay bales and sandbags were used as safety measures, with Bob Gurr himself being the first to ride the completed track.
• ✅ The first ride was described as "rattly and shaky" but the car stopped perfectly, validating the design.
• 🎢 Even years later, the Matterhorn Bobsled ride is noted for its roughness, with Bob Gurr humorously stating he would not ride it again due to its intensity.
