What is the term for the materials used in constructing roller coaster tracks?

The term for the materials used in constructing roller coaster tracks primarily refers to the traditional choices of steel and wood. Steel is commonly used in modern roller coasters for its durability and ability to support complex designs, allowing for smoother and faster rides. Wood has been a historic choice, favored for its classic aesthetic and the unique ride experience it offers, characterized by a more rugged feel and distinct creaks and sounds. The combination of these two materials—steel for precision and performance, and wood for nostalgia and charm—defines the core of roller coaster construction.

Although other materials like aluminum, plastic, and concrete may find some application in specific components of a roller coaster (such as supports, decorative elements, or safety features), they are not typically used for the main track structure itself, which is predominantly made of steel or wood.
