The Käferberg Tunnel (‹See Tfd›German: Käferbergtunnel) is a railway tunnel in the Swiss city of Zürich. The tunnel runs under the Käferberg hill from the western approaches to Zürich Hauptbahnhof to a portal to the south of Oerlikon station. It is 2,119 metres (6,952 ft) long 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. Heading south from the southern portal of the tunnel, the railway first crosses the River Limmat and Hardturmstrasse on a concrete viaduct. Still on viaduct the line splits into two, with the right hand leg being a single-track viaduct that descends into Zürich Altstetten station. The left hand leg, still double track and on viaduct, runs into the upper level of Zürich Hardbrücke station, before continuing its descent into the Hauptbahnhof. The tunnel was opened in 1969. As built, only the Altstetten leg of the southern connecting lines existed, and the tunnel was only usable by freight and other trains that bypassed Hauptbahnhof station. In 1982, Hardbrücke station and its leg of the connecting lines opened, allowing the tunnel to be used by trains running between Hauptbahnhof and Oerlikon. Today the tunnel carries Zürich S-Bahn lines S5, S6, S7, S9, S15, S16 and S21, all of which operate via Hardbrücke. It also carries freight traffic, which runs via the Altstetten link. The Käferberg Tunnel is now one of three different routes from Oerlikon to Hauptbahnhof, each of which tunnels through the intermediate ridge and emerge from adjacent portals to the south of Oerlikon station. Like the Käferberg Tunnel, the Wipkingen Tunnel (opened in 1856) connects to the Hauptbahnhof's western approaches, whilst the Weinberg Tunnel (opened in 2014) accesses the Hauptbahnhof's lower level through platforms from the east.

Kantonsschule Zürich Nord (KZN) is a Swiss cantonal gymnasium (Langzeit-, Kurzzeit, und Fachmittelschule) in Oerlikon, northern Zürich, Switzerland. The school, which first opened in 2012, was formed by the merger of Kantonsschule Zürich Birch and Kantonsschule Oerlikon (see German WP).

Unterstrass is a quarter in the district 6 in Zürich. It was formerly a municipality of its own, having been incorporated into Zürich in 1893. The quarter has a population of 19,921, in an area of 2.46 km2 (0.95 sq mi). In 1962, the faculty of science of the University of Zürich proposed to establish the Irchelpark campus on the Strickhofareal. The first stage the construction of the university buildings was begun in 1973, and the campus was inaugurated in 1979. The construction of the second stage lasted from 1978 to 1983. The campus also houses the anthropological museum Anthropologisches Museum, and the cantonal Staatsarchiv Zürich. Built in 1901 as Rigiblick restaurant, the former Gastsaal was re-opened as Theater Rigiblick in 1984.

The Gustav-Ammann-Park is a public park in Oerlikon, Zurich, is built on the former area of the Bürhle AG and covers 32,291 ft². In 1996, the privately owned park became a preserve. One year later, the formerly nameless facility was handed over to the population as Gustav-Ammann-Park. It was gently renovated in 2004/2005, maintaining all historical garden monuments. The name of the park reminds us of Gustav Ammann (1886–1955), a well-known Swiss landscape architect who worked in the modernist style.

Zürich Wipkingen railway station (German: Bahnhof Zürich Wipkingen) is a railway station in the Wipkingen quarter of the Swiss city of Zürich. It is situated on the Zürich–Winterthur railway line, which was built by the Swiss Northeastern Railway (Schweizerische Nordostbahn).The route towards Zürich HB leads over the Wipkingen viaduct (Wipkinger Viadukt). Immediately at the northern end of the station, the Wipkingen Tunnel starts and connects it to Zürich Oerlikon.

The Louis-Häfliger-Park in Oerlikon, Zurich, covers 5,000 m2 (53,820 sq ft) and is embedded between the Regina-Kägi-Hof co-operative settlement, the existing production buildings for Oerlikon-Contraves AG, and new service buildings. It is a neighbourhood park allowing people who live or work here to relax and meet. The park is named after Louis Häfliger (1904–1993), "Saviour of Mauthausen". He saved the lives of about 40,000 inmates of the Mauthausen concentration camp.

The MFO-Park is a public park in the Oerlikon quarter of the Swiss city of Zürich. The area to the north of Zürich Oerlikon railway station was once home to the extensive works of Maschinenfabrik Oerlikon (MFO), as site that has now been redeveloped as Neu Oerlikon. As part of that redevelopment, four new parks were created, including the MFO-Park, which was created on the footprint of one of MFO's buildings. The project was designed by the architects Burckhardt + Partner, landscape architects Raderschallpartner and structural engineers Basler & Hofmann AG.The park is characterized by its modern and unusual design. The large “Park-Haus” is a double-walled steel-framed construction, 100 m (330 ft) in length, 35 m (115 ft) in width and 17 m (56 ft) high, reminiscent of a conservatory without glass. It is covered by a trellis (or treillage) and covered with climbing plants, resulting in a space that is filled by ever changing light, shadow and smells. The large hall space is broken up by four plant-covered wire chalices. The water basin planted with irises is located in a sunken area that is floored with recycled glass. The spaces between the double walls contain staircases, linking to balconies and platforms at different levels, including a sun deck high up on the roof that offers views over northern Zürich.The MFO-Park accommodates a number of different activities. The facility is suitable for sport and games, for meetings of all kinds, or events such as film screenings, concerts and theatrical performances – all with a baroque backdrop of hedges. Small silent garden rooms with a view into the hall are created in the spaces between the walls, just like opera boxes.The foundation stone was laid in autumn 2001 and the MFO-Park was inaugurated in summer 2002. As originally planned, there was intended to be a second phase which would feature an area with plant-covered pillars in front of the south side of the hall. This phase has not yet been implemented, and the four-story brick building which was originally intended for demolition to make space for this will continue to be used for the time being.The garden has received the following awards: European Garden Award in the category of "Most Innovative Contemporary Park or Garden", awarded by the European Garden Heritage Network EGHN 2010 Award for good architecture in the Zürich canton 2006 - Recognition Award for good architecture from the City of Zürich 2006 2004: MAX on top Vienna, free space 02, 2nd place 2004 Play & Leisure Award Friedrichshafen 2004 BDLA Prize (Association of German Landscape Architects) 2003 - Appreciation Public design-award 2003

District 6 is a district north of the old town in the Swiss city of Zürich. The district comprises the quarters Unterstrass and Oberstrass. Both entities were formerly municipalities of their own, but were incorporated into Zürich in 1893.

Maschinenfabrik Oerlikon was a Swiss engineering company based in the Zürich district of Oerlikon known for the early development of electric locomotives. It was founded in 1876 by the industrialist Peter Emil Huber-Werdmüller, and occupied a large site immediately to the west of Oerlikon railway station. In 1906 the armaments business was demerged to form Schweizerische Werkzeugmaschinenfabrik Oerlikon, which evolved into the technology company OC Oerlikon and the armaments company Rheinmetall Air Defence (formerly Oerlikon Contraves). In 1967 Maschinenfabrik Oerlikon was taken over by Brown, Boveri & Cie, which in 1988 merged with ASEA to form ABB Group. The site of the company's works has been redeveloped, including the innovative public MFO-Park. In the second decade of the 21st century, a project was initiated to expand Oerlikon railway station, with the provision of two additional platform tracks on north-western side of the station. This affected the site of the former office building of Maschinenfabrik Oerlikon, dating from the late 19th century and now a restaurant complex known as Gleis 9. Because of its cultural importance to the region, plans to demolish the building were rejected, and instead the 6,200-tonne (6,800-ton) building was moved 60 meters (200 ft) to the west on specially laid tracks. The move took place in May 2012, and took 19 hours.
