	Trolleybus - Wikipedia, the free encyclopedia
		Like other electric vehicles, trolleybuses are often seen as more environmentally friendly than fossil fuel or hydrocarbon-based vehicles (gasoline, diesel, alcohol, etc.), but the power is not "free", having instead to be produced at centralised power plants, with attendant transmission losses.
		Trolleybus wire switches (in some countries referred to as "frogs") are a standard piece of equipment in places where the line forks into two others or two lines join into one.
		Bradford Trolleybus 758 is kept at The Trolleybus Museum at Sandtoft.

		This trolleybus is a three-axle, four-door vehicle, in which the c-axle (you read correctly, the last axle) is propelled.
		In the roof of the rear of the articulated trolleybus are two electric ventilators.
		Independent electric heating with three-level control of the heating capacity as well as a three-level control of the air supply are used to heat the driver's seat and to defrost the windscreen.

	Some EV History / History of Electric Cars and other Vehicles
		Electric cars, with their heavy loads of batteries, were at a distinct disadvantage in these situations which required being pulled, lifted and pried out of these sinkholes.
		While many urban areas were beginning to install an electrical infrastructure in the late 1800's and early 1900's, often primarily to replace gas street lamps with electric street lamps to save on the labour associated with lamp-lighters, electricity in the home, and even in businesses, was not the common utility it is today.
		The number of electric cars actually sold in 1912 was only a fraction of the number of gasoline cars sold that same year - the registration figures were an artifact of the number of electrics sold in previous years.

	4.1. Period from 1842 to April 1945
		After around the turn of the century the nature of the electricity was as far as possible enlightened and the use of the electricity brought increasingly economic advantages.
		The trolleybus should become the replacement and so the public utilities gave the job for the building of an electric trolleybus system with single pole collector in Eberswalde to the company Brown, Boveri and Cie.
		The trolleybus overhead system was situated partly absent-minded in the side streets of the city, because it was aside vacated by the fleeing German military columns and cut thereby.

	British Trolleybus history
		The father of the trolleybus is usually said to be Werner Von Siemens, because of his experiments in the Berlin suburb of Halense, between Charlottenburg and Spandau Bock (Berlin) for six weeks beginning 29 April 1882.
		The 1909 RET demonstration trolleybus in fact, had a unique version of the under-running Max Schiemann system - the booms were parallel to the body, with the leading boom 'steering' a circular trolley head casting that pivoted on the casting that joined the two booms.
		Electrically, it "is equipped by Dick, Kerr and Co. Ltd." This trolleybus is one of those mysteries.

		The trolleybus has many advantages over buses using diesel or alternative fuels such as natural gas, especially when effects on the environment are considered.
		While some may consider the overhead wiring required by the trolleybus to be intrusive, it actually helps to draw riders by giving transit a permanent presence on the street.

		"Trolley" refers to the trolley poles on the roof of the bus that are used to transmit the electricity from the overhead wires.
		Thus, "Electric trolley bus" is a redundant term, but must be used occasionally to differentiate real trolley buses from the faux trolley cars and cable cars that are actually small buses.

		Orléans is one of a growing number of French cities to adopt an electric light rail tramway system as a major component of their public transport networks.
		A careful choice of internal operating voltage in a hybrid bus, combined with twin trolley poles and overhead wiring, would create a part-time electric trolleybus that can operate either off of grid power or off of its own diesel-electric engines/battery combination.
		Classic trolleybuses, operating only off grid power and their electric motors, are also likely to see a revival in a "Peak Oil" world.

		The difference is that, whereas the tram usually gets its power from only one large cable, with the current escaping through the rails and into the earth, a Tbus uses two, smaller, wires, drawing the current from one and returning it via the other.
		Because Tbuses use electricity which is centrally-generated at the power station, they can use fuel more efficiently than, say, a diesel bus.
		Tbuses are also capable of 'regenerative braking' which means that the braking system is designed to be used as a mini-generator to recapture some of the energy that might otherwise be lost when slowing down.

		They were stripped to their frames, motors were rewound, insulation and electrical components were replaced, new seats and floors were installed and the buses were repainted inside and out.
		He said 40% of the electric fleet was out of service on a daily basis (not because it wasn't dependable but, in part, because he had pulled them off one of their routes) and that the installation of overhead in the new Wentworth garage then being planned would add $1 million to its cost.
		In 2003, some of those gas buses have now been scheduled for scrapping as they are considered no longer economic to repair, they've cost far more and given the citizens less than half the life of some of the "olde" trolleys certain powers couldn't wait to chuck.

	Portland Transport: 30 Years of Trolleybus Advocacy
		If you have six or eight electric bus routes that merge and run for three miles together through downtown with 30 or 40 buses an hour in each direction during the peak hour, total, hey, good for you, but if you have a single long line with fifteen minute headways, well, not a good candidate.
		For God sakes, if anyone with a bright idea suggests that you have the local investor-owned electric utility put up the wires and you buy the power from them, so that the cost of the wires paid for through your utility bill each month, spit in their eye.
		When considering trolleybuses and other modes, if the long-term costs are similar for a given application (such as diesel vs. trolleybus for a short, medium to high ridership line), trolleybus offers one clear advantage: Of all the modes (even rail), it has the quietest operation.

	Portland Transport: What's Up with Trolleybuses?
		The Trolleybus (AKA: electric bus, trolley bus, trolley coach, trackless trolley, trackless tram) is an interesting technology, crossing the rubber-tired bus with the fixed guideway element of overhead caternary wires.
		Regarding Trolleybus age, the vehicles are mechanically simpler than a diesel bus and tend to last longer with less maintenance.
		There have been experimental systems that hide the electrical in a slot under the road, but this slot can clog up with debris, water, and ice, etc. and is more expensive than standard rail to install.

		Evolved out of motorbus and electric streetcar, it is most certainly the newer, and perhaps as some have insisted, "more civilized" form of urban bus transport.

		In cities with trolleybus systems, the cost of adding new lines or building extensions is small when compared to the capital value of the entire system.

		The trolleybus has a facility whereby it can disconnect from the overhead wires and run on batteries - giving it a flexibility to go off route (or for example uphill to Ealing Hospital entrance) - which the tram cannot match and which might be vital in emergencies.
		When the trolleybus encounters illegally parked vehicles (Ealing Borough Council officers have explained that it is extremely difficult to enforce against such parking) it can manoeuvre round them.
