39. Oberleitungsbus
Ein Oberleitungsbus ist ein elektrisch angetriebener Bus, der seine Energie normalerweise über oberhalb der Straße verlaufende elektrische Leitungen und am Fahrzeug angebrachte Stromabnehmer erhält. Anders als eine Straßenbahn fährt ein Oberleitungsbus auf gewöhnlichen Straßenrädern und wird vom Fahrer gelenkt, statt von Schienen geführt zu werden.
Oberleitungsbusse dienen in der Regel dem öffentlichen Personenverkehr und können Busspuren, Haltestellen und andere Einrichtungen des öffentlichen Verkehrs nutzen. Manche modernen Oberleitungsbusse verfügen zusätzlich über Batterien oder Hilfsantriebe, mit denen sie kurze Strecken ohne Verbindung zur Oberleitung fahren können.
What is a trolleybus?
A trolleybus is an electrically powered bus that normally receives electricity from overhead wires while travelling on ordinary road wheels.
Is a trolleybus the same as a tram?
No. A tram runs on rails and follows the path of its tracks. A trolleybus has ordinary tyres and is steered like a conventional bus.
Is a trolleybus an electric bus?
Yes. A trolleybus uses an electric motor, but unlike a battery-electric bus it traditionally receives most or all of its operating power from overhead electrical wires.
How does a trolleybus receive electricity?
Electrical current is normally collected from overhead wires through poles or another current-collection system mounted on the vehicle.
Can a trolleybus drive without overhead wires?
Some trolleybuses can. Modern vehicles may have batteries or auxiliary motors that allow limited operation away from the overhead wiring.
Can a trolleybus change lane?
Yes. Because it is steered rather than rail-guided, a trolleybus can move sideways within the range permitted by its overhead electrical connection and road layout.
Can trolleybuses use bus lanes?
Yes, where local rules permit. Trolleybuses operating public-transport services can normally use infrastructure reserved for authorised buses and public transport.
Do trolleybuses have priority when leaving stops?
This depends on the local traffic law. Some countries require other drivers to allow public-transport buses, including trolleybuses, to leave designated stops.
Should drivers slow down near a stopped trolleybus?
Yes. Passengers may be boarding, leaving or crossing the roadway. Drivers should approach carefully and give passengers sufficient space where required.
Does a trolleybus produce exhaust emissions?
A trolleybus operating entirely on electric power produces no combustion-engine exhaust emissions at the vehicle. Non-exhaust emissions from tyres, brakes and road wear can still occur.
