The Brusio spiral viaduct, some say “Brusio circular viaduct”, is a single-track nine-arched stone spiral railway viaduct. It is located near Brusio, Switzerland, and was opened on 1 July 1908. The Brusio spiral viaduct is a part of the Bernina Railway. Normally, you would think, that this model railway layout was made by Swiss model railroaders.
