Description: "Anderson's Piano" is a set of wires and signals at the Pass of Brander, near Falls of Cruachan in Scotland, that try to detect when there might be a boulder on the track. They're 140 years old, and so far no-one's been able to find a better solution — but they're working on it. Thanks to all the team at Network Rail and Scotland's Railway: scotlandsrailway.com Edited by Michelle Martin twitter.com/mrsmmartin I'm at tomscott.com on Twitter at twitter.com/tomscott on Facebook at facebook.com/tomscott and on Instagram as tomscottgo
