Este sitio agrupa dos líneas ferroviarias históricas que cruzan los Alpes suizos por dos puertos de montaña. Inaugurada en 1904, la línea del Albula está situada en la parte nordeste del sitio y tiene 67 km de longitud. Comprende un conjunto impresionante de obras de ingeniería formado por 42 túneles y galerías cubiertas y 144 puentes y viaductos. La línea del Bernina tiene 61 km y cuenta con 13 túneles y galerías y 52 puentes y viaductos. El sitio es un ejemplo notable de la utilización del ferrocarril, a principios del siglo XX, para acabar con el aislamiento de las poblaciones de los Alpes centrales e inducir un cambio socioeconómico duradero en la vida de los montañeses. Este ferrocarril es una realización excepcional en el plano técnico, arquitectónico y ambiental, que encarna los logros que pueden alcanzar la arquitectura y la ingeniería civil en perfecta armonía con el paisaje circundante.

The Rhaetian Railway in the Albula/Bernina Landscapes represents an exemplary railway development for the disenclavement of the Central Alps at the beginning of the 20th century. The railway’s socio-economic consequences were substantial and lasting for mountain life, the interchange of human and cultural values, and changes in the relationship between man and nature in the West. The Rhaetian Railway offers a wide diversity of technical solutions for the establishment of the railway in often severe mountain conditions. It is a well designed construction that has been realised with a high degree of quality and it has remarkable stylistic and architectural homogeneity. The railway infrastructure moreover blends in particularly harmoniously with the Alpine landscapes through which it passes. Criterion (ii): The Rhaetian Railway of Albula/Bernina constitutes an outstanding technical, architectural and environmental ensemble. The two lines, today unified in a single transalpine line, embody a very comprehensive and diversified set of innovative solutions that bear witness to substantial interchanges of human and cultural values in the development of mountain railway technologies, in terms of its architectural and civil engineering achievements, and its aesthetic harmony with the landscapes through which they pass. Criterion (iv): The Rhaetian Railway of Albula/Bernina is a very significant illustration of the development of mountain railways at high altitudes in the first decade of the 20th century. It represents a consummate example of great quality, which was instrumental in the long-term development of human activities in the mountains. It offers diversified landscapes in conjunction with the railway that are significant of this period of the flourishing of a relationship between man and nature. The railway infrastructures of the Albula and Bernina lines form an authentic ensemble of great integrity. Their technical operation and their maintenance ensure long-term conservation of high quality. The Rhaetian railway company that has unified them and carries out their technical management has introduced technical changes and innovations that are compatible with the concept of authenticity of technological properties that are still in use. The legal protection in place is adequate. The management system of the property is satisfactory, though a reinforcement of the presentation to the public of the founding heritage aspects of the property is desirable.
