Synonym discussion

Sense: noun/1

While all four terms describe forms of urban rail transport, they differ in scale and track arrangement. 'Light rail' refers to a modern electric railway on dedicated tracks carrying passengers within a city at moderate speeds. 'Light railway' (chiefly British) has a similar meaning but can also include heritage or narrow-gauge lines. 'Metro' (also 'subway' or 'underground') is a heavier, fully grade-separated system designed for high capacity and frequency, often entirely underground. 'Streetcar' (North America) or 'tram' (UK / Europe) runs on tracks laid in the street, sharing space with cars and pedestrians, with shorter distances and smaller vehicles. For example, a journey from a suburban park-and-ride into the city centre would use light rail; a cross-town trip under busy avenues would use the metro; and a short ride through a historic district would use a streetcar.

Etymology

LatinOld FrenchEnglish

'Light' refers to the lighter weight of the trains and tracks compared with mainline railways; the term dates from the 1970s when cities began building modern urban rail systems distinct from older heavy rail and streetcars. 'Rail' comes from Old French 'reille' (iron bar), from Latin 'regula' (straight rod). The compound 'light rail' was popularised by transport planners to describe a middle-weight system between a tram and a metro.
