The Bernina Railway, part of the Rhaetian Railway network, is a testament to early 20th-century engineering prowess. Construction began in 1908 and the line opened in 1910, connecting St. Moritz with Tirano across the Bernina Pass. It was designed not just for practical transportation but also with tourism in mind, offering access to the stunning alpine regions. What makes the Bernina Railway particularly unique is its gradient – it is one of the steepest adhesion railways in the world, meaning it operates without the need for a rack-and-pinion system, relying solely on the friction between the wheels and the rails. In 2008, the Bernina Line, along with the Albula Line, was inscribed as a UNESCO World Heritage site, recognized for its harmonious integration into the landscape and its innovative engineering. Today, the Bernina Express continues to be a crucial link and a beloved scenic route, preserving its historic infrastructure while providing a modern, comfortable travel experience through one of Europe's most awe-inspiring natural environments.
