Wanderlust World Wanderlust World Roller coasters are not made of medals. Medals are commemorative objects (gold, silver, bronze alloys). Coasters are engineered structures built from industrial materials:
Steel: Track (tubular, box-girder, or I-beam), support structure, train chassis, wheel hubs, fasteners. High-strength low-alloy steels (A572, A588) for fatigue resistance.
Aluminum: Train bodies, some support components—lighter, corrosion-resistant.
Fiberglass/composites: Train shells, theming elements, some track fairings.
Concrete: Foundations, footers, station buildings.
Polyurethane/nylon: Wheel tires (road, upstop, guide)—critical for ride dynamics.
"Medal" vs. "metal"—a phonetic slip. Or "medal" as shorthand for "metal alloy." But the distinction matters: medals symbolize achievement; coasters embody it—through metallurgy, dynamics, and safety engineering.
Wood coasters: Southern yellow pine, Douglas fir (structural); steel track caps. Hybrid (RMC): Steel track on wood structure. Modern steel: Precision-fabricated, CNC-bent, factory-welded track segments. Future: Carbon fiber track, 3D-printed nodes, smart materials.
Coasters are applied materials science at 120 km/h—not ceremonial tokens.
