With the arrival of the canals and the railways, the Castlefield area developed very quickly in the Victorian period. The canals drew both housing and factories westward, and by the 1820's the developing Georgian grid had been supplemented by the rapid spread of infill back to industrial housing. In 1844 the Liverpool Road Passenger Station was given over to goods traffic as the passenger railway station moved to Hunt's Bank. The opening of Central Station in 1879, extended the viaduct network through the castle-in-the-field. In the mid-18th century the population of Castlefield had reached around 50,000 people, but the population was halved again with the arrival of the railroad. Built in 1825, St. Matthew's Church, split Camp Field in two, thus splitting the site of a market. The markets continued to function, and were rehoused in two cast iron structures (the Lower and Higher Campfield Markets). It was noted in 1886, the commercial activity of the area had, "done more to clear away the City's slums than any amount of sanitary legislation." The turn of the century brought major developments on the edge of the area with the building of shops and offices.
