This intermediary signal box was located between New Cumnock (to the west) and Kirkconnel. The box was on the south side of the line. There was a trailing crossover.
The box closed in 1940 and the crossover taken out.
Today the former box is probably most noteworthy for David L. Smith's article 'The Hold-up at the Cairn - A Mogul with a coal train sticks between Kirkconnel and New Cumnock' which can be found in his 'Legends of the Glasgow and South Western Railway in LMS days' book.
