After the colliery was closed, due to an underground fire. The site of the colliery was then used for many years as a training centre for National Coal Board employees. Surrounded by agricultural farmland, much of the village's expansion was due to mining and canal transport. In the early 1900s, Haydock had no fewer than three railway stations–Haydock, Ashton-in-Makerfield, and Haydock Park–along the line which passed through from St. Helens to Lowton. Governance Haydock was a township in the parish of Winwick before being made a civil parish in 1866. The village was in the poor law union of Warrington in the 19th century before being created an urban district in 1894.
