A monorail is a rail-based transportation seestem based on a single rail, which acts as its sole support an its guideway. The term is an aa uised variously tae describe the beam o the seestem, or the vehicles travelin on such a beam or track. The term originates frae jynin mono (ane) an rail (rail), frae as early as 1897,[1] possibly frae German engineer Eugen Langen who cried an elevated railway seestem wi wagons suspendit the Eugen Langen Ane-railed Suspension Tramway (Einschieniges Hängebahnsystem Eugen Langen). The transportation seestem is eften referred tae as a railway.[2]

Colloquially, the term "monorail" is eften uised erroneously tae describe ony furm o elevatit rail or fowk mover.[3] In fact, the term refers tae the style o track,[note 1] nae its elevation.
