Stoosbahn, Schwyz, Switzerland

Formally the Standseilbahn Schwyz– Stoos, it’s got supercool barrel-shaped carriages which rotate to keep passengers on a level floor, and it’s built on a crazy slope of 47.7 degrees.

It opened in 2017 and was hailed as the “world’s steepest railway” as it rises a whopping 2,441ft on a 5,710ft track.
