Dietikon is a railway station in Switzerland, situated in the city of Dietikon. The station is located on the Swiss Federal Railway's Zurich to Olten main line and is also the terminus of the metre gauge Bremgarten-Dietikon-Bahn (BD). The station is served by Zurich S-Bahn lines S3 and S12 and some long distance trains on the main line, and by S-Bahn line S17 on the BD.[1][2]
The first station on the site was built by the Swiss Northern Railway in 1847, as part of their pioneering line from Zurich 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 entusiasts' club. It 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.[3]
The station has five through platforms on the main line, and two terminal platforms on the BD. Whilst the BD 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.
For most of the day, line S3 provides 2 train per hour (tph) to Zurich and Wetzikon and 1 tph to Lenzburg and Aarau. Line S12 provides 2 tph to Zurich and Winterthur and 2 tph to Baden and Brugg. Line S17 provides 2 tph to Wohlen, with an additional 2 tph as far as Bremgarten on weekdays only. Additionally there is a single InterRegio train per hour between Zurich Airport and Basel SBB that bypasses Zurich Hauptbahnhof but calls at Dietikon in both directions.[4]
