The Manchester, South Junction and Altrincham Railway opened in 1849, and led to the middle classes using Sale as a commuter town, a residence away from their place of work. This resulted in Sale's population more than tripling by the end of the 19th century. The land in Sale Moor was the cheapest in the town because the soil was poor and difficult to cultivate, which was part of the reason the area was common land until the early 19th century. However, when the railway opened, Sale Moor was close to the station and became the most expensive area in Sale. Villas were built in Sale Moor, and a few in Ashton upon Mersey as the demand for land increased. They were often decorated with stained glass or different coloured bricks in an attempt to make them "mansions in miniature" for the aspiring middle class.
