Sihl in the context of "Platzspitz"

Zürich Hauptbahnhof, often shortened to Zürich HB or just HB, and known in English as Zurich Main Station, is the largest railway station in Switzerland and one of the busiest in Europe. Located at the northern end of Zurich’s Bahnhofstrasse, the station is a major railway hub, with services to and from across Switzerland and neighbouring countries such as Germany, Italy, Austria and France. The station was originally constructed as the terminus of the Spanisch Brötli Bahn, the first railway built completely within Switzerland. Serving up to 2,915 trains per day, Zürich HB is one of the busiest railway stations in the world. It was ranked as the best European railway station in 2023 and 2024.

Zürich HB is one of 29 stations in Zurich that are located within fare zone 110 of the Zürcher Verkehrsverbund (ZVV).. It is situated at the northern end of the Altstadt (lit. 'old town') and east of the Europaallee in central Zurich, near the confluence of the rivers Limmat and Sihl (the Sihl actually passes through the station in a tunnel with railway tracks both above and below). The station is on several levels, with platforms both at ground and below-ground level, tied together by underground passages and the ShopVille shopping mall. It is also connected with the Zurich HB SZU subsurface station of SZU, but shares no tracks with the latter. Zürich HB's railway yards extend about 4 km (2.5 mi) to the west.

Eurogate Zurich – originally HB-Südwest (lit. 'Central Station Southwest'), later Stadtraum HB (lit. 'urban space at central station'), and today known as Europaallee Zürich (lit. 'Europe Avenue') – is one of the urban developments on the southwest side of Zurich's Central Station (Zürich Hauptbahnhof, or Zürich HB) in Switzerland.

Located in the city's District 4, near the city centre, Europaallee was completed in 2020 and includes shops, restaurants, offices (e.g. Google), apartments, the college of education (Pädagogische Hochschule Zürich) and a hotel. Europaallee is mostly pedestrianized and features two rows of Ginkgo trees. It also includes a fountain nicknamed 'Europuddle'. The site is connected to the urban developments north of the railway tracks via a pedestrian bridge (Negrellisteg (de)) and the western underpass of Central Station. It is linked with Bahnhofplatz, the square in front of Central Station, via Postbrücke over the river Sihl.

The Limmat is a river in Switzerland. The river commences at the outfall of Lake Zurich, in the southern part of the city of Zurich. From Zurich it flows in a northwesterly direction, continuing a further 35 km until it reaches the river Aare. The confluence is located north of the small town of Brugg and shortly after the mouth of the Reuss.

The main towns along the Limmat Valley downstream of Zurich are Dietikon, Wettingen, and Baden. Its main tributaries are the Linth, Wägitaler Aa and Jona, all via Lake Zurich, the Sihl in Zurich, and the Reppisch in Dietikon.
