TrolleyFavorite form of transportation Trolleywelcome. Trolley''This article refers to the mass transit vehicle. For other uses see Trolley (disambiguation)'' A trolley or trolley car is an electric streetcar that draws power from a live suspended wire. Outside of the United States of America and Canada, a trolley is usually known as an electric tram. The term "trolley" derives from the trolley pole that collects live power from an overhead wire or cable, sometimes simply strung, sometimes as catenary (railways). The trolley pole in turn derived its name from the "trolley wheel" that was formerly the chief means of contact between car and wire as the wheel "trolled" behind the moving car. Modern trolleys often do not use a trolley wheel (using a metal shoe with a carbon insert instead) or even a trolley pole, a pantograph (rail) being the preferred means of contact. Other streetcars are sometimes called trolleys, even though this may be technically incorrect, as for a cable car or a conduit car that drew power from an underground third rail. Trolleys and trolley lines are also often described as light rail, especially if the line has significant off-street running. Tourist buses made to look like a streetcar are also sometimes called trolleys; see tourist trolley. Electric buses, which still overwhelmingly use twin trolley poles (one for live current, one for return) are also called trolleys, trolleybuses, or trackless trolleys. Vehicles Electric railways Light rail Trolley== Terminology == If 'a trolley is a kind of streetcar' as the 2nd para clearly stated, why not say so in the first para, rather than saying it is 'a common carrier ... rail vehicle that ... operates on a regular schedule, picking up and dropping off passengers when hailed', which applies to all streetcars, but misses the fundamental point of a streetcar, which is that it runs in the street. Simplifying text on that basis. -- User:Chris j wood 23:43, 10 Jan 2005 (UTC) See other meanings of words starting from letter: TTA | TB | TC | TD | TE | TF | TG | TH | TI | TJ | TK | TL | TŁ | TM | TN | TO | TP | TR | TS | TU | TW | TX | TY | TZ |Words begining with Trolley: Trolley Trolley Trolley Trolley Trolley-bus Trolley-pole Trolleybus Trolleybus Trolleybuses Trolleypole Trolleys Trolley_(disambiguation) Trolley_bus Trolley_car Trolley_cars Trolley_car_suburb Trolley_coach Trolley_dodger Trolley_park Trolley_pole Trolley_problem Trolley_problem Trolley_Square Trolley_Square.
