The Trolleybus Zurich is the trolleybus system of the Swiss city ​​of Zurich . The Zurich public transport company (VBZ) operates - in addition to the Zurich tram and various bus lines - six trolleybus lines that are integrated into the Zurich Transport Association (ZVV). The total length of the route, without the 83 route, is 53.8 kilometers. Every year 54.1 million passengers are transported, 117.2 million passenger kilometers are performed and 5,400,000 car kilometers are driven. In 2011 the trolleybus handled 18.5 percent of the total VBZ passenger volume.

The information for the total travel time and the number of stops are shown separately for the direction of travel specified under route and the corresponding opposite direction, whereby the first value stands for the specified direction. All stops including the departure and end stations are taken into account for each direction of travel.

Line 31 to Schlieren was the only trolleybus line to cross the city limits of Zurich. This route was created in 1956 as a replacement for tram line 1 and a section of line 2, which emerged from the Limmattal tram . Due to the work on the Limmattalbahn , line 31 has only been running to Altstetten station since December 2019. With the completion of the Limmattalbahn, line 31 is to be extended again from the Farbhof to the last Micafil stop still in the city area, and a turning loop with a stop is to be created in the area of ​​Hermetschloostrasse. In return, tram line 2 is to serve the extra-urban section of line 31 to Schlieren. There are also additional reinforcement courses on line 46 between Rosengartenstrasse and Central (in the morning) and between Bahnhofquai / HB and Lehenstrasse (in the afternoon). However, these are generally driven by diesel buses.

Since the timetable change in December 2019, route 83 has also been considered a trolleybus route. In spring 2020, a total of eight trolleybuses of the latest generation will gradually replace the diesel buses previously used. The vehicles have to cover the distance between Hardplatz and Altstetten station without overhead lines. Between Hardplatz and Milchbuck they use the overhead line and recharge their batteries in the process.

history

The Zurich trolleybus was opened on May 27, 1939 by what was then the Zurich City Tram , or St. St. Z. for short . After the Lausanne trolleybus and the Winterthur trolleybus , it was the third modern trolleybus operator in Switzerland. De facto, the trolleybus operation initially belonged to the legally independent transport company Autobusbetrieb der Städtische Strassenbahn Zürich . This was founded in 1927 as a vehicle operation for the Zurich city tram and was renamed in 1935. It was not until March 1949 that the two parts of the company were merged, and the Zurich City Transport Authority was established, and Zurich Transport Authority since 1978 . Since opening, the trolleybus network has developed as follows:

particularities

Lines C or 34 were isolated from the rest of the trolleybus network between their opening in 1946 and 1956. The vehicle was exchanged by means of so-called bow trolleys on tram rails. To this day, the trolleybus catenary network is closely linked to that of the tram: for example, only two rectifier stations are used exclusively for the trolleybus. In some places the return line to the rectifier takes place via the rails of the tram. There is also a special trolleybus test route on the premises of the central workshop in Altstetten ; this ring route is not connected to the rest of the trolleybus network.

Another special feature is the catenary crossing in Friesenberg , where line 32 crosses the Uetlibergbahn, which is operated with 1200 volts DC . In contrast, the electrification of bus line 62 at the catenary of the Swiss Federal Railways failed : A catenary crossing in Affoltern was not approved for safety reasons due to the high voltage of 15,000 volts.

Battery trolleybus number 200 with newly designed front and rear sections at the terminus at Milchbuck

When Albisriederplatz was redesigned in 2015, it was decided not to cross the overhead lines of lines 33, 72 and 83 again with the contact wires of tram lines 2 and 3. The trolleybuses therefore lower their pantographs at Albisriederplatz (direction of travel Hardplatz) or Hardplatz (direction of travel Albisriederplatz) and drive with their auxiliary electric drive to the next station, where threading funnels enable automatic wire-in.

future

Transport companies and the city of Zurich plan to expand the trolleybus network in the future. Early 2024 is provided Bus number 69 ( Milchbuck- Bucheggplatz - ETH Hönggerberg ) and mid-2025, the line 80 ( Oerlikon station -ETH Hönggerberg- Triemlispital switch) Overhead line operation. The steeply inclined routes, which open up the university location from different directions, are already partially prepared for the use of trolley buses and are well suited for the changeover. The current passenger numbers and the development potential also promise a worthwhile use of double-articulated trolleybuses on the Hönggerberg lines. From the point of view of transport companies and the city council, the advantages of electrical operation compensate for the higher investment costs, especially with regard to the implementation of the 2000-watt society . The budget for the new infrastructure is 44 million Swiss francs.

With the planned extension of tram line 2 from Farbhof to Schlieren Geissweid as part of the Limmattalbahn project (2019), the trolleybus route between Schlieren and Micafil, where line 31 will turn in the future, will probably be eliminated. In the course of the tram extension to Affoltern (2027), line 32 would now turn at Bucheggplatz.

The double-articulated trolleybuses initially only had route 31 as their main route, on which they began service in September 2007 and have served all courses since 2008. Since the beginning of 2009, individual routes on line 32 have also been running with double articulated trolleys, before this was also completely switched to lightrams when the timetable changed in December 2012. Due to the associated increase in capacity - while at the same time thinning the cycle from five to six minutes - it was possible to reduce the run-out during rush hour from 18 to 14 courses and the total number of trolleybuses to be reduced accordingly. For the use of the double articulated wagons, individual stops on the two lines had to be converted as they are around seven meters longer than a conventional articulated wagon. Before that, at the beginning of 2006 there was an extensive trial run of a double articulated vehicle from the Geneva trolleybus .

Former inventory

The FBW trolleybus 79 built in 1974, taken in 1979
The O 405 GTZ number 140 in 2005 on route 33

Initially, the Zurich trolleybus had six solo cars at its disposal; they came from the manufacturers Saurer , Tüscher , FBW and SWS , differed from one another technically and in terms of car construction, and carried company numbers 51 to 56. By 1957, the number of two-axle vehicles of various types had increased to 57 units .

In 1957 the VBZ received their first articulated trolley prototype of the type GTr51 from FBW, SWS and MFO , it was numbered 101. The subsequent series procurement between 1959 and 1964 comprised the cars 102 to 133. The second articulated car series from 1974/1975 consisted of the Car 70 to 100 and came from FBW. These were so-called VST standard trolleybuses of the type 91 GTL, also known locally under the nickname Jumbo . With them, the last solo car could be replaced.

Some vehicles of the first two articulated trolley series, the seven cars 73, 105, 107, 109, 111, 129 and 132, were handed over to Chile in 1991 and 1992 . As the last of these used cars, car 129 was withdrawn from the Valparaíso trolleybus at the end of December 2016 .

The articulated cars from the 1950s were replaced by the first series of the type O 405 GTZ from Daimler-Benz and ABB . This comprised the prototype 1 (built in 1986) and the series cars 2 to 36 (built from 1988 to 1989) and was replaced by the low-floor Swistrolley 3. The second articulated car series from the 1970s was accordingly replaced by the second series O 405 GTZ in 1992/1993. This comprised 43 copies with the numbers 101-143, the last four representatives of which - the last Zurich high-floor wagons - were retired in November 2015.

The Swistrolley prototype built in 1991 remained a one-off . This demonstration car was temporarily put into regular service in Zurich under road number 50 and was Zurich's first low-floor trolley. In 1996 it was finally sold at short notice to the Biel transport company. The duo bus number 51 of the type O 405 GNTD also remained a loner . This second low-floor trolley in Zurich was in trial use between October 1997 and March 1999.

  • The Swisstrolley prototype was also in use in Zurich under the number 50, here already in 2008 on the Biel / Bienne trolleybus

  • The former FBW 51 solo car 86, shown here as car 847 in Geneva in 1971

  • The former articulated trolley 105, here in 2015 on the Chilean trolleybus Valparaíso where it kept its old number

  • The former articulated trolley 122, here in 2006 as trolley 217 in Sibiu, Romania

  • The earlier car 129 also made it to Valparaíso, but was given a two-part windshield and a new company number

Garage

All vehicles are deployed from Garage Hardau. It is planned to use the outside facilities of the Kalkbreite depot to park trolley buses in the future. The additional space required is related to the further procurement of double-articulated trolleybuses. The main maintenance of the vehicles takes place in the central workshop in Altstetten.
