The Aarau–Suhr railway line was a standard gauge railway line in the canton of Aargau, Switzerland. It ran {{convert|4.2|km}} from {{rws|Aarau}} to {{rws|Suhr}}, providing a connection between the Bözberg and Zofingen–Wettingen lines. The Swiss National Railway (SNB) opened the Aarau–Suhr and Zofingen–Wettingen lines on 6 September 1877.{{sfn|Wägli|Jacobi|2010|p=19}} The line passed to Swiss Federal Railways in 1902. SBB electrified the line from Aarau to {{rws|Zofingen}} via Suhr on 15 July 1946.{{sfn|Wägli|Jacobi|2010|p=71}} SBB closed the line 11 December 2004 to permit the re-routing of the narrow gauge Menziken–Aarau–Schöftland railway line off surface streets. The rebuilt line opened on 22 November 2010.{{Cite news |last=Widmer |first=Toni |date=16 November 2010 |title=Suhr/Buchs - Wynental- und Suhrentalbahn ist endlich weg von der Strasse |language=de |work=Aargauer Zeitung |url=https://www.aargauerzeitung.ch/aargau/lenzburg/wynental-und-suhrentalbahn-ist-endlich-weg-von-der-strasse-ld.2034706 |access-date=20 November 2021}}
