Other forms: trams; tramming; trammed
A tram is a trolley or a streetcar—it's a vehicle that transports people using electricity from overhead cables while running on tracks that are set into the street.
In the U.S., you might also call a tram a cable car or light rail. If you've been on a streetcar in San Francisco or a trolley in Philadelphia, you've ridden a tram. The word tram was originally a Scottish term for the wagons that are used in coal mines, stemming from a Middle Flemish word meaning "rung or handle of a barrow."
