Northern Lines Crewe to Manchester including the Styal LineNorthern Lines Crewe to Manchester including the Styal Line 20. 95 by Vic Mitchell & Keith Smith The complex and fascinating history of this very early route is illustrated in detail, as is the "Stockport Bypass", created in the 20th century to relieve traffic congestion at the old junctions. Known as the Styal Line, this has received little attention from photographers, neither has the more recent Manchester Airport branch. This is rectified herein.
