The name of the record-breaking longest passenger train in Switzerland is the Capricorn (specifically a consist of 25 "Capricorn" trainsets). In late 2022, the Rhaetian Railway (RhB) officially broke the world record by running a train that measured 1,906 meters (about 1.2 miles) long. This massive train consisted of 100 carriages and was operated by seven train drivers and 21 technicians working in perfect synchronization. It traveled along the spectacular Albula Line, a UNESCO World Heritage route, crossing 48 bridges and passing through 22 tunnels, including the world-famous Landwasser Viaduct. While this specific mega-train was a one-time event to celebrate the 175th anniversary of Swiss railways, the "Capricorn" trains themselves are the modern workhorses of the Graubünden region in 2026. For daily travelers, the longest regular scheduled train in Switzerland is typically the InterCity 1 (IC1) or InterCity 5 (IC5), which can reach lengths of nearly 400 meters, but they remain much shorter than the historic 1.9km "Endless Snake" that put the Rhaetian Railway in the Guinness World Records.
