The southern stretch of the line between Stockport and Guide Bridge was built by the
Manchester and Birmingham Railway, at around the time of its merger into the
London and North Western Railway (LNWR). The contract was let to
John Brogden and Sons in October 1845. The northern section from Guide Bridge to Stalybridge was built by the
Sheffield, Ashton-under-Lyne and Manchester Railway in 1845. This later became part of the
Manchester, Sheffield and Lincolnshire Railway (MS&LR).
Guide Bridge avoiding line Congestion around Guide Bridge led to the LNWR building a new line to avoid the station. Known as the
Stalybridge Junction Railway, it ran from Denton Junction, then under the
MS&LR main line east of Guide Bridge, parallel to the existing Guide Bridge-Stalybridge line, before joining the main line again just west of Stalybridge station. As well as relieving congestion, it also had the advantage of allowing LNWR trains to bypass MS&LR tracks altogether. The line was completed in 1893, with stations at and . A local Stockport-Stalybridge passenger service ran on this line until 25 September 1950. The line was closed completely in 1968 and was dismantled in the early 1970s. As it ran mostly on brick viaducts, which have since been demolished, little physical trace now remains of the line. ==Route==
