The Bonnyrigg railway line refers to the historical railway services that served the town, primarily the one on the Peebles Railway and the Esk Valley Railway. Both lines have been closed, with the main Peebles line closing to passengers in 1962 and goods in 1965, while the Esk Valley line closed to passengers in 1951. The former station sites are now used for other purposes, such as public paths or housing developments.
This geocache was hidden by the bull patrol of the Bonnyrigg Scout group as part of the geocashing badge.
