The Weinberg Tunnel (German: Weinbergtunnel) is a railway tunnel in the Swiss city of Zürich. The tunnel runs from the western approaches to Zürich Hauptbahnhof railway station, east under the station and city centre before turning north and surfacing on the southern approach to Zürich Oerlikon railway station, and allows trains running between east and west to pass through Zürich without reversal. It includes a new set of underground platforms at Zürich Hauptbahnhof, and carries twin standard gauge (1,435 mm or 4 ft 8+1⁄2 in) tracks electrified at 15 kV AC 16 2/3 Hz using overhead catenary.The tunnel was opened on 14 June 2014, and forms part of the Altstetten–Zürich–Oerlikon cross-city line, also known as the Durchmesserlinie Zürich, which also includes new elevated approach tracks from Altstetten to Zürich Hauptbahnhof, and the rebuilding of Oerlikon station with two additional tracks and platforms. At Zürich Hauptbahnhof, the tunnel serves a pair of underground island platforms, with four platform tracks, numbered as Hauptbahnhof tracks 31 to 34 but sometimes referred to as Löwenstrasse station. These platforms are linked to the station's other platforms and facilities, both underground and surface, by a complex of subways and shopping malls.The Weinberg Tunnel is one of three different routes from Oerlikon to Hauptbahnhof, each of which tunnels through the intermediate ridge. Unlike the Weinberg Tunnel, the other two, the Wipkingen Tunnel and the Käferberg Tunnel, both connect to the Hauptbahnhof's western approaches. All three tunnels emerge from adjacent portals to the south of Oerlikon station.The tunnel is used by both long-distance passenger trains and by suburban trains on Zürich S-Bahn lines S2, S8 and S14. From December 2015, when the full Altstetten–Zürich–Oerlikon cross-city line is planned to open, it is expected that the line will be served by 460 trains per day, comprising 320 S-Bahn services and 140 long-distance services.Along its route, the Weinberg tunnel passes under several other tunnels, including the Hirschengraben rail tunnel that links Zürich Hauptbahnhof and Zürich Stadelhofen stations, the now disused Letten rail tunnel, and the Milchbuck road tunnel.

The Milchbuck Tunnel is a motor road tunnel in Switzerland, and forms part of the A1L motorway from Zürich Schwamendingen to Zürich Letten, where the tunnel's southern portal lies on Wasserwerkstrasse, which leads into central Zürich. Constructed in 1978, the tunnel is 1,910 metres (6,270 ft) in length.A proposed second tunnel bore (to create two separate tunnels for two directions of traffic) was turned down. Now, only one lane handles traffic into downtown Zurich, one lane handle traffic leaving the city, with an emergency lane in the middle. By 2006, the emergency services in the tunnel has been upgraded, with the escape path being added. At the northern portal in the direction to the city, the entrance to Irchel underground car park is to the left of the lane. At about the midpoint of the Milchbuck tunnel, the Weinberg rail tunnel passes beneath it.

Zürich Letten (German: Bahnhof Zürich Letten) is a former railway station in the Swiss city of Zürich. It is situated on the old route of the Lake Zürich right bank railway (Rechtsufrige Zürichseebahn) from Zürich HB to Rapperswil via Tiefenbrunnen. Radical changes to the local railway geography in conjunction with the opening of the Zürich S-Bahn system led to the closure of the station in 1989, but the station building still exists, and the trackbed and viaducts are used as a pedestrian path/cycling route. The former railway station is adjacent to the Letten Power Station on the Limmat.

The Letten Tunnel (German: Lettentunnel) is a disused railway tunnel in the Swiss city of Zürich. It is situated on the old route of the Lake Zürich right bank railway (Rechtsufrige Zürichseebahn) from Zurich Hbf station to Rapperswil station. Radical changes to the local railway geography led to the tunnel being superseded in 1990, and closed and sealed by 2002.As built in 1894, the right bank railway was a single track line that departed from Zürich Hbf in a westerly direction, before performing a clockwise 270 degrees turn via a viaduct over the Limmat, the principal river flowing through the city of Zürich. It then passed through Letten station and the Letten Tunnel in order to reach Stadelhofen station. By rail the distance between Zurich Hbf and Stadelhofen was some 5 kilometres (3.1 mi), despite the fact that they are only 1.5 kilometres (0.93 mi) apart in a straight line. In 1990 the Letten Tunnel was replaced by the Hirschengraben Tunnel, which took a direct route from new through low-level platforms at Zurich Hbf under the Limmat to Stadelhofen. After the new route opened, the original railway line and tunnel fell into disuse. The railway line was closed in 1998, and by 2002 it had been removed, and the tunnel was filled in and sealed off.The northern portal of the tunnel can still be observed from a location close to the former Letten railway station and the Letten power station on the banks of the Limmat. The northern approaches to the tunnel, including the bridge over the Limmat, are now used as a cycle and pedestrian path.

The Sihl is a Swiss river that rises near the Druesberg mountain in the canton of Schwyz, and eventually flows into the Limmat in the centre of the city of Zürich. It has a length of 73 km (45 mi), including the Sihlsee reservoir, through which the river flows. Water is abstracted from the river at the Sihlsee, leading to decreased downstream water flows and a consequent reduction in water quality.The river flows through, or along the border of, the cantons of Schwyz, Zürich and Zug. The main settlements of the Sihl Valley are all in the canton of Zürich, and include the towns of Langnau am Albis and Adliswil, along with a south-western segment of the city of Zürich. Above Langnau am Albis, some 13 km (8.1 mi) from the confluence with the Limmat, there are no major settlements alongside the river, and only a few small villages. Whilst the town of Einsiedeln is situated close to the Sihlsee, it is actually in the valley of a tributary river, the Alp.
