See world's longest passenger train run through Swiss Alps The 1.2 mile (1.9 kilometer) long train broke the record on October 29 after completing an over 15-miles-long trip.

Switzerland holds the world record for the longest passenger train, a feat achieved by the Rhaetian Railway (Rhätische Bahn) on October 29, 2022. To celebrate the 175th anniversary of Swiss railways, the company assembled a massive train consisting of 100 carriages, stretching approximately 1,910 meters (nearly 1.2 miles) in length. The train traveled along the Albula Line, a UNESCO World Heritage route known for its dramatic spirals and viaducts, covering the 25-kilometer journey from Preda to Alvaneu. This historic run required seven drivers and 21 technicians to coordinate the multi-unit system over the mountainous terrain. The record was officially confirmed by Guinness World Records, showcasing Swiss engineering precision and highlighting the country's commitment to high-capacity, sustainable rail infrastructure in one of the world's most challenging geographic environments.
