Bremgarten–Dietikon railway line

The Bremgarten–Dietikon railway line (German: Bremgarten-Dietikon-Bahn, BD) is a railway line in Switzerland. It connects Wohlen and Bremgarten in the canton of Aargau with Dietikon in the canton of Zürich. Passenger service on the line now forms part of the Zürich S-Bahn, branded as the S17, and a frequent service is provided, with trains running up to every 15 minutes.

The line was opened in stages, and under different ownership, between 1876 and 1912. Whilst the earliest section to be opened, between Wohlen and Bremgarten, was built as a traditional branch line, the later section between Bremgarten and Dietikon was built as rural electric tramway. Whilst much of the line has been upgraded, this is still apparent in the long stretches of roadside track, and stretches of street running in Dietikon.

Today the line is owned and operated by BDWM Transport AG, a company that also operates bus services in the region.

History

Wohlen-Bremgarten railway

The route between Wohlen and Bremgarten West was built to standard gauge by the Aargauische Südbahn railway, which connected Aarau and Rotkreuz via Wohlen. The service began on September 1, 1876, operated by steam locomotives.
