The 1.2-mile-long train with 100 coaches ventured 15.5 miles on Saturday through mountains, tunnels and across bridges to claim the record for the world's longest passenger train, Swiss railway company Rhaetian Railway said in a statement. Seven train drivers and 21 technicians operated the train as it rode from the Albula Tunnel in Preda to the Landwasser Viaduct just outside Filisur along the famous Albula-Bernina route, a UNESCO World Heritage designation, ending in Bergün. The previous record was set in Belgium by the National Belgian Railway Company in 1991, according to Euro News. #trains #swissalps
