This yard and improvements to the harbour railways were built after the opening of the Glasgow, Paisley, Kilmarnock and Ayr Railway which originally terminated on the north back of the river and had a short branch over a viaduct to the south bank. The improvements took over facilities which were abandoned by the Ayr Waggonway and greatly improved them.
These locations are along the line.
This yard is in the north of Ayr, directly north of Newton-on-Ayr station. The yard is largely associated with the operation of Ayr Harbour for coal export and the various Ayrshire coal loading points. With the demise of Scottish Coal (April 2013) and the reduced demand for coal for power stations the yard is now very under used.
