Around Stairfoot to the south of Barnsley, a complex junction of lines sprung up including a short branch constructed by the Midland, connecting its main line at Cudworth with the Sheffield-Barnsley route. It completed a diversion known as the Chapeltown Loop which bypassed a bottleneck around Rotherham. The Dearne valley was spanned by an iron viaduct, supported on 10 brick pillars. It still stands today and, following refurbishment, forms part of the National Cycle Network.
