The Pass of Brander stone signals, also known as Anderson's Piano, are a series of railway signals situated in the Pass of Brander, between Loch Awe and Taynuilt stations on the Oban branch of the West Highland Line in Scotland. A screen of wires, linked to semaphore signals, are erected on the mountainside alongside the railway. In the event of one or more wires being broken, signals in each direction are automatically placed at 'danger'. They are part of a warning system that advises train drivers to exercise caution in the event of a rock-fall, and cover a section of track that is just over 4 miles (6.4 km) in length.

The West Highland Line is a railway line linking the ports of Mallaig and Oban in the Scottish Highlands to Glasgow in Central Scotland. The line was voted the top rail journey in the world by readers of independent travel magazine Wanderlust in 2009, ahead of the notable Trans-Siberian line in Russia and the Cuzco to Machu Picchu line in Peru. The ScotRail website has since reported that the line has been voted the most scenic railway line in the world for the second year running.
