The line was extremely expensive to build with extensive earthworks. The navvies were accommodated in specially-built houses near the Rising Sun pub, which still exist, and are known as the ""Navvy Mansions"." The line from Edgeley Junction, just south of Stockport, to Hazel Grove was electrified in 1981 on the 25 kV AC overhead system. This allowed electric trains on the route from , via Sale, to serve the station until that line was closed for conversion to Manchester Metrolink operation in late 1991; electric services to and from Piccadilly continued thereafter.
