Hay is a very significant railway site in the State system. The station building reflects political developments between the States and interstate rivalries that resulted in the construction of a grand building at an important freight site. The whole complex indicates the importance of the site in the production of wool and the policy of shipping it to Sydney rather than through the southern states. The line was opened in response to an aggressive Victorian economic policy offering special rebates for
shipping grain through Victoria. There was an unstated plan for the line to be extended to Adelaide through Hay and the scale of the building is evidence of this. The buildings are of very high quality with fine detailing and are among the most important structures in the State. It is the only first class station in the State not to be built on a main line or at a major junction which gives it added significance. All of the buildings and structures at Hay are of high significance and it is important that the site be retained as a whole. Hay railway station was listed on the
New South Wales State Heritage Register on 2 April 1999 having satisfied the following criteria.
