elevated train

Synonym discussion
Sense: noun/1
All four are forms of urban rail, but they differ in where and how they run. An 'elevated train' is carried on tracks built high above the streets, so passengers look down on traffic and rooftops. A 'subway' is the opposite: it runs through tunnels below ground, which keeps the streets clear but hides the view. A 'monorail' rides on a single raised beam rather than two ordinary rails, and is often seen at airports or theme parks. A 'tram' stays at street level, sharing the road with cars and pedestrians, and usually stops more often. When you want to stress that a city train is lifted above the road on supports, 'elevated train' is the precise choice; for the underground version, say 'subway'.

Etymology
The phrase joins two old borrowings. 'Elevated' comes from Latin 'elevare', 'to lift up' (from 'levare', to raise), and reached English in the late Middle Ages. 'Train' comes through Old French from Latin 'trahere', 'to pull', first meaning a line of things drawn along behind. The compound 'elevated train' is much newer: it appeared in the late 19th century to name the raised city railways then being built in places like New York and Chicago, where the line was lifted onto supports to clear the busy streets below.
