The Original Wooden Version

A Möbius Loop Coaster is a clever design. Named after the German mathematician August Ferdinand Möbius, the track has no real beginning or end.
Instead, it is a continuous loop: the first side becomes the second, which then returns to the first. Yes, this is very confusing and very clever.
The result is a racing coaster that uses two tracks with two trains running side by side, so you return to the opposite side of the station you left.

Steel Variation

Möbius loop coasters were only wooden coasters until 2010, when Preston & Barbieri built  Nitro at Dennlys Parc in France as the first steel model.
Since then, they’ve built new steel coasters, including Max Adventures Master Thai at Mirabilandia in Italy, but no wooden ones have been built since Montaña Rusa at La Feria Chapultepec Magico in Mexico City, which opened in 1964 and closed in 2019. (Pictured at the top of this page.
