Dietikon railway station is a railway station in Switzerland, situated in the canton of Zürich and the city of Dietikon (Limmat Valley). The station is located on the Swiss Federal Railway's Zürich to Olten main line and is also the terminus of the metre gauge Bremgarten–Dietikon railway (BD).

Dietikon station is not to be confused with Dietlikon railway station located in Dietlikon in the Glatt Valley (canton of Zürich).

History 
The first station on the site was built by the Swiss Northern Railway in 1847, as part of their pioneering line from Zürich to Baden, and hence was one of the first railway stations in Switzerland. The original station building was constructed on the northern side of the railway line and still exists, albeit now used as a rail enthusiasts' club.

The original station was replaced in the 1860s by a new building on the southern, city centre, side of the line. This in turn was replaced in the 1970s by the current large station building on the same side of the line.

Operation 
The station has five through platforms on the main line, two terminal platforms on the Bremgarten–Dietikon railway (S17) and, since 2022, two terminal platforms on the Limmattal light rail line (Limmattalbahn), which is operated by AVA.

Whilst the Bremgarten–Dietikon  terminal platforms are alongside their main line equivalents, trains approach them via street running track through the centre of Dietikon and across the station frontage. Also in the station frontage is a large covered bus station, used by local and regional bus services, and the Limmattalbahn (Zürich tram route 20), which operates between  and  over Dietikon using mostly its own tracks.

Service 
Dietikon station is served by Zürich S-Bahn lines S11, S12, S19, and S42; by some long-distance trains on the main line; and by S-Bahn line S17 on the BD.
