There are some 13 trains per hour to Zürich Hauptbahnhof, Zürich's main city centre station, with a journey time of between 10 and 15 minutes. By changing trains at Hauptbahnhof, most other places in Switzerland can be reached in a few hours.
Swiss Northern Railway
The line opened on 7 August 1847 and was the first line located entirely on Swiss territory. Shortly after 11:30 am, the arrival of the first official train in Zurich was announced with gun salute. He brought the invited guests and members of the Aargau authorities from Baden to Zurich. The locomotive No. 1 «Limmat» required only 23 minutes, which would correspond to an average speed of 42 km / h. After celebrations and sightseeing of the train station infrastructure the train left Zurich for Baden at 13:00 with 140 invited guests; scheduled operations started two days later. Every day there were four trips in each direction. The 20 km journey took 45 minutes with the trains stopping at Altstetten, Schlieren and Dietikon. Soon after the opening, the line began to be called the "Spanisch-Brötli bahn" ("Spanish bun railway") because the Zürich gentry sent their servants by train to Baden to buy these buns in order to impress their clients at Sunday morning teas. Previously their servants had to set out from Baden at midnight on foot with the buns. The buns were apparently derived from buns made in Milan during the 17th century when it was under Spanish control. Under the laws of the canton they could only be made in Baden.
