Authorised in 1882, the Cornhill Branch was built to link the farming communities of north Northumberland with the market town of Alnwick, and link the North Eastern Railway's Kelso line to its Alnwick Branch.
Increased bus competition in the 1920s led to passenger trains being withdrawn on 22 September 1930, although the service resumed briefly during the Second World War to serve RAF Milfield, near Akeld.
Inglenook Sidings, created by Alan Wright (1928 - January 2005), is a well-known model railway train shunting puzzle.
It consists of a specific track layout, a set of initial conditions, a defined goal, and rules which must be obeyed while performing the shunting operations.
The puzzle is based on Kilham Sidings, on the Alnwick-Cornhill branch of the North Eastern Railway (NER).
