The Wynental and Suhrental Railway was a privately owned railway company in the canton of Aargau in Switzerland. It was formed by the merger of the Aarau-Schöftland Railway with the Wynental Railway in 1958. It in turn merged with BDWM Transport in 2018 to form Aargau Verkehr (AVA).

The Schöftland–Aarau–Menziken railway line is a metre gauge railway line in the canton of Aargau in Switzerland. It provides a through service, in the form of an inverted 'V', from Schöftland to Menziken via Aarau. The two parts of the V were built separately, with the Aarau–Menziken railway line running through the Wynental, and the Aarau–Schöftland railway line running through the Suhrental.
