Trams | Light Rail
A tram, light rail, monorail, and city train are modes of train transportation within a city and typically run along a track and transport both passengers and cargo. Trams, also known as streetcars, or trolleys, emerged in the early 1800s, and typically run on tramway tracks on urban streets. A light rail, also known as light rail transit (LRT) or fast tram, is faster and quieter than trams. The concept of the light rail was first developed by H. Dean Quinby in 1962. A monorail is a train that travels on a single rail railway. Its first prototype made by Ivan Elmanov was first seen in Russia in 1820. A city train, also known as a metro, underground, subway, or tube, are electrically powered. The earliest city train system, the Metropolitan Railway, was opened in London in 1863.
