The Landwasser Viaduct (German: Landwasserviadukt) is a single track six-arched curved limestone railway viaduct. It spans the Landwasser River between Schmitten and Filisur, in the Canton of Graubünden, Switzerland. Designed by Alexander Acatos, it was built between 1901 and 1902 by Müller & Zeerleder for the Rhaetian Railway, which still owns and uses it today. A signature structure of the World Heritage-listed Albula Railway, it is 65 metres (213 ft) high, 136 metres (446 ft) long, and one of its ramps exits straight into the Landwasser Tunnel.
The Glenfinnan Viaduct sweeps majestically across a valley at the North end of Loch Shiel in the Scottish Highlands. It carries the steam trains from Fort William to the fishing port of Mallaig on the west coast, from where the ferry runs to Skye.
