A lot to see in this view from the 126 meter high "Prime Tower" (Zürich's highest building), with the Letzigrund stadium (Soccer and track and field) on the left and Altstetten on the right. In the middle Switzerlands longest railway viaduct, the new 1156 meter long single track Letzigraben bridge, which lifts the express trains leaving Zürich towards the west up to 16 meter high over the track field to Zürich Altstetten. The allowed maximum speed over this bridge is 120 km/h, the maximum down grade towards Altstetten 4.0 %! In the foreground, a highspeed tilting train ETR 610 of Trenitalia is on the bridge from the Herdern holding sidings to the main station, for a run to Milano. A commuter double deck train DPZ with locomotive Re 450 is running from Hardbrücke towards Oerlikon via the Käferberg line. Behind the Letzigraben bridge are the buildings of the SBB Reparaturcenter Altstetten (repair center), the former industrial works or "Hauptwerkstatt".
