With a name meaning "One Hundred Valleys", the Centovalli Railway connects Locarno in Switzerland to Domodossola in Italy. Construction of the line was delayed with the advent of the First World War, so it did not open until 1923. However, with its beautiful bridges over some incredible lakeside and valley scenery, the line has remained open ever since, being especially popular with tourists.
The railway never used steam engines, and is currently powered by diesels. However, some of the heritage trams from the early days of the line are used on special occasions.
