King County Metro Fleet
As of 2017, King County Metro operates the 10th largest fleet of buses in the United States, with a total of 1,540 buses. Upon taking over transit operations on January 1, 1973, Metro used buses acquired from predecessor agencies Seattle Transit System and the Metropolitan Transit Company, still painted in their original colors. Metro acquired the 91-bus fleet of the Metropolitan Transit Company in December 1972 at a cost of $2.75 million. The first fleet of new buses ordered by Metro arrived in June 1976, consisting of 145 diesel coaches manufactured by AM General. In 1978, Metro became the first large transit agency in North America to introduce articulated buses to its fleet, which required some bus stops to be rebuilt to accommodate coaches. The fleet of 151 buses were manufactured by German maker MAN as part of a bulk order with other large U.S. transit agencies. Vehicle types In 1978, Metro was the first large transit agency to order high-capacity articulated buses (buse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid Bus
A hybrid electric bus is a bus that combines a conventional internal combustion engine propulsion system with an electric propulsion system. These type of buses normally use a Diesel-electric powertrain and are also known as hybrid Diesel-electric buses. The introduction of hybrid electric vehicles and other green vehicles for purposes of public transport forms a part of sustainable transport schemes. Powertrain Types of hybrid vehicle drivetrain A hybrid electric bus may have either a parallel powertrain (e.g. Volvo B5LH) or a series powertrain (e.g. some versions of the Alexander Dennis Enviro400 MMC). Plug-in hybrid A plug-in hybrid school bus effort began in 2003 in Raleigh, NC when Advanced Energy began working between districts across the country and manufacturers to understand the needs of both. The effort demonstrated both a technical and business feasibility and as a result was able to secure funding in 2005 froNASEOto purchase up to 20 buses. The resulting R ...

King is the title given to a male monarch in a variety of contexts. The female equivalent is queen, which title is also given to the consort of a king. *In the context of prehistory, antiquity and contemporary indigenous peoples, the title may refer to tribal kingship. Germanic kingship is cognate with Indo-European traditions of tribal rulership (c.f. Indic ''rājan'', Gothic ''reiks'', and Old Irish ''rí'', etc.). *In the context of classical antiquity, king may translate in Latin as '' rex'' and in Greek as ''archon'' or ''basileus''. *In classical European feudalism, the title of ''king'' as the ruler of a ''kingdom'' is understood to be the highest rank in the feudal order, potentially subject, at least nominally, only to an emperor (harking back to the client kings of the Roman Republic and Roman Empire). *In a modern context, the title may refer to the ruler of one of a number of modern monarchies (either absolute or constitutional).

Dead Mileage
Dead mileage, dead running, light running, empty cars or deadheading in public transport and empty leg in air charter is when a revenue-gaining vehicle operates without carrying or accepting passengers, such as when coming from a garage to begin its first trip of the day. Similar terms in the UK include empty coaching stock (ECS) move and dead in tow (DIT). The term '' deadheading'' also applies to the practice of allowing employees of a common carrier to use a vehicle as a non-revenue passenger. For example, an airline might assign a pilot living in New York to a flight from Denver to Los Angeles, and the pilot would simply catch any flight going to Denver, either wearing their uniform or showing ID, in lieu of buying a ticket. Also, some transport companies will allow employees to use the service when off duty, such as a city bus line allowing an off-duty driver to commute to and from work, free. Additionally, inspectors from a regulatory agency may use transport on a dead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, World War 1, Supermarine Nighthawk, an anti-Zeppelin night fighter.Andrews and Morgan 1987, p. 21.
