The Wynental and Suhrental Railway (, WSB) was a privately owned railway company in the canton of Aargau in Switzerland. It was formed by the merger of the Aarau-Schöftland Railway (, AS) with the Wynental Railway (, WTB) in 1958. It in turn merged with BDWM Transport in 2018 to form Aargau Verkehr (AVA). The company owned and operated the Menziken–Aarau–Schöftland railway line, a metre gauge railway line from Menziken to Schöftland via Aarau. The line continues to run, under the ownership of Aargau Verkehr. History The Wynental Railway In 1871, several municipalities in the Wynental founded a committee requesting a concession for two railway lines, from Aarau via Oberkulm to Reinach, and from Beinwil am See via Reinach to Menziken. Both were planned as standard gauge lines operated with steam engines. A year later the project was granted by the authorities of the canton Aargau, but was not executed, mainly due to disagreements over the exact line through the narrow valley. Eventually the section between Beinwil am See and Menziken was built and opened in 1883 by the Seetal Railway (now SBB). Later on, this route was extended to Münster (today's Beromünster). Eventually, the Wynental municipalities came to the conclusion that a narrow-gauge electric tram would be more economic. In January 1903 construction works were started. The opening of the Wynentalbahn (WTB) between Aarau and Reinach was on March 5, 1904, the extension to Menziken followed a few weeks later on 1 May. Originally the line had its starting point in the street on the north side of SBB's Aarau railway station. In 1924, the WTB opened its own station south of the SBB railway lines. The Aarau-Schöftland Railway In the Suhrental too, there were thoughts about constructing a railway. Here, however, from the beginning on, a narrow gauge electrically powered line was planned, in the largest part of the route to be operated as a tramway. The project of the company Brown, Boveri & Cie (BBC) received the license and soon thereafter the construction works began. The Aarau-Schöftland Railway (AS) started operation on November 19, 1901. The planned extension of the AS from Schöftland to Triengen (connecting to the Sursee-Triengen-Bahn) was never realized. Like the Wynental Railway, the Aarau-Schöftland Railway had its starting point in the street on the north side of SBB's Aarau railway station. When the Wynental terminus was moved south of the station, the connection
