Synonym discussion

Sense: noun/1

Monorail, elevated train, light rail, subway, and maglev are all types of urban rail transit, but they differ in track design and position relative to the ground. A monorail runs on a single raised track, whereas an elevated train runs on a traditional two-rail track that is raised above street level. Light rail runs on two parallel rails, often at street level alongside cars and pedestrians. A subway travels entirely underground, while a maglev train floats above the track using magnetic force, reaching much higher speeds but at far greater cost. For example, Tokyo's monorail connects the city centre to Haneda Airport on a single elevated beam, while the city's subway tunnels run deep beneath the streets.

Etymology

GreekOld FrenchEnglish

'Monorail' combines the Greek prefix 'mono-' (meaning 'one' or 'single') with the English word 'rail' (a metal bar that trains run on). The prefix 'mono-' appears in other English words such as 'monotone' (a single, unchanging tone) and 'monopoly' (control by one seller). The word 'rail' comes from Old French 'reille', meaning an iron bar. The term 'monorail' was first used around the early 1900s to describe an experimental single-track railway in Germany.
