Monorail
A monorail is a railway in which the track consists of a single rail, typically elevated. The term is also used to describe the beam of the system, or the vehicles traveling on such a beam or track. The term originates from joining ''mono'' (one) and ''rail'' (rail), from as early as 1897, possibly from German engineer Eugen Langen, who called an elevated railway system with wagons suspended the ''Eugen Langen One-railed Suspension Tramway'' (Einschieniges Hängebahnsystem Eugen Langen). Colloquially, the term "monorail" is often used to describe any form of elevated rail or people mover. More accurately, the term refers to the style of track,〔The term "track" is used here for simplicity. Technically the monorail sits on or is suspended from a guideway containing a singular structure. There is an additional generally accepted rule that the support for the car be narrower than the car.〕 not its elevation, with 'Mono' being the Greek numeral prefix for one and 'Rail' meaning 'rail' structure utilized.〔 〕 ==Differentiation from other transport systems== Monorails have found applications in airport transfer and medium capacity metros. To differentiate monorails from other transport modes, the Monorail Society says “Monorail n. 1. A single rail serving as a track for passenger or freight vehicles. In most cases rail is elevated, but monorails can also run at grade, below grade or in subway tunnels. Vehicles either are suspended from or straddle a narrow guide way. Monorail vehicles are wider than the guide way that supports them.”
