Zürich Hauptbahnhof (often shortened to Zürich HB) (English: Zurich Main Station) is the largest railway station in Switzerland. Zurich is a major railway hub, with services to and from across Switzerland and neighbouring European countries such as Germany, Italy, Austria and France. Constructed as the terminus of the Spanisch Brötli Bahn, the first railway built completely within Switzerland, it is one of the oldest railway stations in Switzerland. Serving up to 2,915 trains per day, Zurich HB is one of the busiest railway stations in the world.
It is in the Altstadt or old town in central Zurich at the confluence of the rivers Limmat and Sihl, where the river Sihl passes the station in a tunnel between the tracks on the upper and the lower level. The station railway yards extend about 4 km (2.5 mi) to the west.
The station is included in the Swiss Inventory of Cultural Property of National Significance.
