Dunscore (NX858840) was one of the four principal stations on the Cairn Valley Light Railway (CVR) branch, from Dumfries.

[1] The CVR was nominally independent, but was in reality controlled by the Glasgow and South Western Railway.

The station cost £212 to build in red brick with cream painted poster boards and chocolate-coloured framing.

Electrically controlled home and starter signals were present for both directions and a telephone system was provided for communication between stations.

[5] In about 1936 the London Midland and Scottish Railway removed the original signals and the line was worked by a brass Key Token Trains, however replacement signals were provided to control the passing loop.
