Description

A roller coaster is a type of amusement ride employing a form of elevated railroad track that carries passengers on a train through tight turns, steep slopes, and other elements. Roller coasters are usually designed to produce a thrilling experience, though some roller coasters aim to provide a more gentle experience. Trains consist of open cars connected in a single line, and tracks are typically built and designed as a complete circuit in which trains depart from and return to the same loading station. The rides are often found in amusement parks around the world. There are an estimated 6,000 extant roller coasters as of July 2025.
