What is difference between a streetcar and a trolley?
The term “trolley” refers to an electric vehicle that operates over fixed rails usually imbedded in pavement. The trolley itself is a small device, usually a wheel or slider, which touches the overhead wire to carry the flow of electricity from the wire to the electric motors. It’s this device that gives the vehicle its name. A streetcar is another term which can be used interchangeably to describe the same vehicle; in some countries, the word “tram” is used instead. In Washington D.C., the term used was two words: “street car”. “Streetcar” is the term preferred by dictionaries and most transit systems.
