Outside Europe, 14 vehicles built by, and for, the Shanghai trolleybus system in mid-1999 were the first reported low-floor trolleybuses in Southeast Asia. Wellington, New Zealand , took delivery of its first low-floor trolleybus in March 2003, and by the end of 2009 had renewed its entire fleet with such vehicles. Unlike Europe, where low floor means "100%" low floor from front to back, most "low floor" buses on other continents are actually only low-entry or part-low floor. In

Responses varied, with some systems keeping their high-floor fleets, and others retiring them early but, in many instances, selling them second-hand for continued use in countries where there was a demand for low-cost second-hand trolleybuses, in particular in Romania and Bulgaria. The Lausanne system dealt with this dilemma in the 1990s by purchasing new low-floor passenger trailers to be towed by its high-floor trolleybuses,
873-453: A switch while braking or accelerating through a switch without activating it. One variation of the toggle switch will simulate accelerating by causing a larger power draw (through a resistance grid), but will not simulate coasting and prevent activation of the switch by cutting the power. A Selectric switch has a similar design, but the contacts on the wires are skewed, often at a 45-degree angle, rather than being lined up. This skew means that

Number of minorities in Bremen by nationality as of 31 December 2022: The recent influx has somewhat moderated the tendency toward an accelerated ageing of the population. As it is, more than half the population of the state of Bremen are over 50, and more than a quarter are over 60. The Stadtbürgerschaft (municipal assembly)
1067-401: A transmitter, often attached to a trolley pole. The receiver is attached to the switch and causes it to trigger if the correct code is received. This has the advantage that the driver does not need to be accelerating the bus (as with a power-on/power-off switch) or trying to make a sharp turn (as with a Selectric switch). Trailing switches (where two sets of wires merge) do not require action by

#17331066247481164-432: A trolleybus going straight through will not trigger the switch, but a trolleybus making a turn will have its poles match the contacts in a matching skew (with one pole shoe ahead of the other), which will trigger the switch regardless of power draw (accelerating versus coasting). For a Fahslabend switch, the trolleybus' turn indicator control (or a separate driver-controlled switch) causes a coded radio signal to be sent from
1261-697: A trolleybus to get around a route blockage or can reduce the amount (or complexity) of overhead wiring needed at operating garages (depots). This capability has become increasingly common in newer trolleybuses, particularly in China, North America and Europe, where the vast majority of new trolleybuses delivered since the 1990s are fitted with at least limited off-wire capability. These have gradually replaced older trolleybuses which lacked such capability. In Philadelphia , new trackless trolleys equipped with small hybrid diesel-electric power units for operating short distances off-wire were placed in service by SEPTA in 2008. This

6499-416: The fuselage section (excluding the cockpit) of the A400M military transport aircraft takes place before delivery on to Spain. More than 3,100 persons are employed at Airbus Bremen, the second largest Airbus site in Germany. As part of the Centre of Excellence – Wing/Pylon, Bremen is responsible for the design and manufacture of high-lift systems for the wings of Airbus aircraft. The entire process chain for
6596-443: The high-lift elements is established here, including the project office, technology engineering, flight physics, system engineering, structure development, verification tests, structural assembly, wing equipping and ultimate delivery to the final assembly line. In addition, Bremen manufactures sheet metal parts like clips and thrust crests for all Airbus aircraft as part of the Centre of Excellence – Fuselage and Cabin. In Bremen there
6693-416: The largest producers in North America and Western Europe – ones whose production totalled more than 1,000 units each – included the U.S. companies Brill (approx. 3,250 total), Pullman-Standard (2,007), and Marmon-Herrington (1,624); the English companies AEC (approx. 1,750), British United Traction (BUT) (1,573), Leyland (1,420) and Sunbeam (1,379); France's Vétra (more than 1,750); and
6790-437: The left bank of the Lower Weser, through which the Ochtum flows, is the Weser Marshes, the landscape on its right bank is part of the Elbe-Weser Triangle . The Lesum , and its tributaries, the Wümme and Hamme , the Schönebecker Aue and Blumenthaler Aue , are the downstream tributaries of the Weser. The city's municipal area is about 38 kilometres (24 miles) long and 16 kilometres (10 miles) wide. In terms of area, Bremen
6887-404: The line profile used. This battery allows them not to depend on overhead lines. They can thus operate with a mix of electric wire and batteries (60% of the time on the wire and 40% on the battery). With the development of battery technology in recent years, trolleybuses with extended off-wire capability through on-board batteries are becoming popular. The on-board battery is charged while the vehicle
6984-603: The loop. Because of its proximity to the University of British Columbia (UBC) and the University Endowment Lands , it is heavily used by students. All routes going westbound from Dunbar Loop terminate at UBC during regular weekday hours. This article about a building or structure in British Columbia is a stub . You can help Misplaced Pages by expanding it . This article about transport in British Columbia
7081-595: The northwestern borough of Burglesum. As a result, Bremen has the lowest high point of all the German states . Bremen has a moderate oceanic climate ( Köppen climate classification Cfb ) due to its proximity to the North Sea coast and temperate maritime air masses that move in with the predominantly westerly winds from the Atlantic Ocean. However, periods in which continental air masses predominate may occur at any time of
7178-445: The operator. The frog runners are pushed into the desired position by the trolley shoe, or the frog is shaped so the shoe is guided onto the exit wire without any moving parts. Well over 200 different trolleybus makers have existed – mostly commercial manufacturers, but in some cases (particularly in communist countries ), built by the publicly owned operating companies or authorities. Of the defunct or former trolleybus manufacturers,
7275-522: The overhead wires, usually by accelerating, at the moment the poles pass over the contacts (the contacts are lined up on the wires in this case). If the trolleybus "coasts" through the switch, the switch will not activate. Some trolleybuses, such as those in Philadelphia and Vancouver, have a manual "power-coast" toggle switch that turns the power on or off. This allows a switch to be triggered in situations that would otherwise be impossible, such as activating
7372-621: The past. For an overview, by country, see Trolleybus usage by country , and for complete lists of trolleybus systems by location, with dates of opening and (where applicable) closure, see List of trolleybus systems and the related lists indexed there. Of the systems existing as of 2012, the majority are located in Europe and Asia, including 85 in Russia and 43 in Ukraine. However, there are eight systems existing in North America and nine in South America. Trolleybuses have been preserved in most of
7469-452: The primary transit mode or as a supplement to rapid transit and commuter rail networks. Trolleybuses are quieter than internal combustion engine vehicles. Mainly a benefit, it also provides much less warning of a trolleybus's approach. A speaker attached to the front of the vehicle can raise the noise to a desired "safe" level. This noise can be directed to pedestrians in front of the vehicle, as opposed to motor noise which typically comes from
7566-710: The private Jacobs University Bremen was founded. All major German research foundations maintain institutes in Bremen, with a focus on marine sciences: The Max Planck Society with the Max Planck Institute for Marine Microbiology , and the Gottfried Wilhelm Leibniz Scientific Community with the Center for Tropical Marine Ecology (zmt). The Bremerhaven-based Alfred-Wegener-Institute of the Helmholtz Association closely cooperates with
7663-408: The production network of Airbus SAS and this is where equipping of the wing units for all widebody Airbus aircraft and the manufacture of small sheet metal parts takes place. Structural assembly, including that of metal landing flaps, is another focal point. Within the framework of Airbus A380 production, assembly of the landing flaps (high lift systems) is carried out here. The pre-final assembly of
7760-445: The rear of a bus and is more noticeable to bystanders than to pedestrians. Trolleybuses can share overhead wires and other electrical infrastructure (such as substations ) with tramways. This can result in cost savings when trolleybuses are added to a transport system that already has trams, though this refers only to potential savings over the cost of installing and operating trolleybuses alone. The wires are attached to poles next to
7857-606: The record year 2010 counting 84 days with a snow cover. Nevertheless, snow accumulation of more than 20 centimetres (8 in) remains exceptional, the record being 68 centimetres (26.8 in) of snow on 18 February 1979. The warmest months in Bremen are June, July, and August, with average high temperatures of 20.2 to 22.6 °C (68.4 to 72.7 °F). The coldest are December, January, and February, with average low temperatures of −1.1 to 0.3 °C (30.0 to 32.5 °F). Typical of its maritime location, autumn tends to remain mild well into October, while spring arrives later than in
7954-419: The reference periods of 1961–90 and 1991–2020. This trend has continued over the last 10 years (2011–2020), which average 1680 hours of sunshine, almost 200 hours more than in the international reference period of 1961–90. Nevertheless, especially the winters remain extremely gloomy by international standards with December averaging hardly more than one hour of sunshine (out of 7 astronomically possible) per day,
8051-505: The right-wing group Phalanx 18 was banned by the city-state of Bremen. One of the two mayors ( Bürgermeister ) is elected President of the Senate ( Präsident des Senats ) and serves as head of the city and the state. The current mayor is Andreas Bovenschulte . Provisional results; the AfD did not reach the 5% threshold in Bremerhaven (and will hence only receive seats for votes from Bremen),
8148-580: The southern borough of Neustadt-Neuenland and is Germany's 12th-busiest airport . Bremen is a major cultural and economic hub of Northern Germany. The city is home to dozens of historical galleries and museums, ranging from historical sculptures to major art museums, such as the Bremen Overseas Museum ( Übersee-Museum Bremen ) or the Weserburg . The Bremen City Hall and the Bremen Roland form
8245-497: The southwestern parts of the country. Bremen's economy boomed in line with the West German Wirtschaftswunder of the 1950s and 60s. This saw the growth, and permanent settlement, of a large migrant worker population, drawn largely from Turkey and southern Europe. A new wave immigration occurred after the turn of new century, following the entry of Poland , Bulgaria and other former East Bloc countries into
8342-455: The street and carefully stretched and mounted so that they are the same width apart and same height over the road (usually about 18 to 20 feet (~5.7m)). The pair of wires is insulated from the poles and provides about 500 to 600 volts to the bus below. Trolleybus wire switches (called "frogs" in the UK) are used where a trolleybus line branches into two or where two lines join. A switch may be either in
8439-479: The switch assembly, which power a pair of electromagnets , one in each frog with diverging wires ("frog" generally refers to one fitting that guides one trolley wheel / shoe onto a desired wire or across one wire. Occasionally, "frog" has been used to refer to the entire switch assembly). Multiple branches may be handled by installing more than one switch assembly. For example, to provide straight-through, left-turn or right-turn branches at an intersection, one switch
8536-597: The temporal power of the Church , and after the Thirty Years' War with Sweden , the masters of the surrounding Duchy of Bremen-Verden . George 1 Louis , the Elector of Hannover (and from 1714, King of Great Britain and Ireland ) who in 1715 acquired Bremen-Verden, recognized Bremen as a free city in 1720. The city was captured in 1806 and then annexed by France in 1810, before it regained independence in 1815. In 1871, Bremen
8633-467: The transition from high-floor to low-floor has meant that some equipment previously placed under the floor has been moved to the roof. Some transit operators have needed to modify their maintenance facilities to accommodate this change, a one-time expense. Since the end of 1997, no double-decker trolleybuses have been in service anywhere in the world, but, in the past, several manufacturers made such vehicles. Most builders of double-deck trolleybuses were in
8730-500: The world's fourth passenger-carrying trolleybus system, which operated at Bielatal (Biela Valley, near Dresden ), Germany. Schiemann built and operated the Bielatal system , and is credited with developing the under-running trolley current collection system, with two horizontally parallel overhead wires and rigid trolleypoles spring-loaded to hold them up to the wires. Although this system operated only until 1904, Schiemann had developed what
8827-575: The world's largest trolleybus manufacturer, producing over 65,000 since 1951, mostly for Russia/CIS countries, but after its bankruptcy, its facilities were partially loaned out to PC Transport Systems . Škoda is Western and Central Europe's largest and the second largest in the world, having produced over 14,000 trolleybuses since 1936, mostly for export, and it also supplies trolleybus electrical equipment for other bus builders such as Solaris, SOR and Breda. In Mexico, trolleybus production ended when MASA , which had built more than 860 trolleybuses since 1979,
8924-429: The year 2014 has been the warmest year on record averaging 11.1 °C (52.0 °F), making Bremen the second-warmest German state after Berlin in 2014. While Bremen is located in the comparatively cloudy northwestern part of Germany, there has been a significant increase in average sunshine hours over the last decades, especially in the months of April, May, and July, causing the annual mean to rise by 121 hours between
9021-555: The year and can lead to heat waves in the summer and prolonged periods of frost in the winter. In general though, extremes are rare in Bremen and temperatures below −15 °C (5.0 °F) and above 35 °C (95.0 °F) occur only once every couple of years. The record high temperature was 37.6 °C (99.7 °F) on 9 August 1992, while the official record low temperature was −23.6 °C (−10.5 °F) on 13 February 1940. On 13 October 2018, Bremen recorded its warmest October day on record with 28.6 °C (83.4 °F). However,
9118-574: Was acquired in 1998 by Volvo. However, Dina , which is now that country's largest bus and truck manufacturer, began building trolleybuses in 2013. A significant change to trolleybus designs starting in the early 1990s was the introduction of low-floor models, which began only a few years after the first such models were introduced for motorbuses . These have gradually replaced high-floor designs, and by 2012, every existing trolleybus system in Western Europe had purchased low-floor trolleybuses, with
9215-472: Was drawn by Prussia into the German Empire . With its new sea anchorage and wharves at Bremerhaven, it was the principal port of embarkation for German and central European emigrants to the Americas, and an entrepôt for Germany's late developing colonial trade. The Norddeutscher Lloyd (NDL), founded in Bremen in 1857, became one of the world's leading shipping companies. In the twentieth century, Bremen,
9312-584: Was the first UK city to replace a tram route with trolleybuses, while Wolverhampton , under the direction of Charles Owen Silvers, became world-famous for its trolleybus designs. There were 50 trolleybus systems in the UK, London's being the largest. By the time trolleybuses arrived in Britain in 1911, the Schiemann system was well established and was the most common, although the Cédès-Stoll (Mercédès-Électrique-Stoll) system
9409-549: Was tried in West Ham (in 1912) and in Keighley (in 1913). Smaller trackless trolley systems were built in the US early as well. The first non-experimental system was a seasonal municipal line installed near Nantasket Beach in 1904; the first year-round commercial line was built to open a hilly property to development just outside Los Angeles in 1910. The trackless trolley was often seen as an interim step, leading to streetcars . In
