Tram

A tram (also known as tramcar; in North America known as streetcar, trolley or trolley car) is a rail vehicle which runs on tracks along public urban streets (called street running), and also sometimes on separate rights of way. The lines or networks operated by tramcars are called tramways.

Tramways powered by electricity, which were the most common type historically, were once called electric street railways. Trams also include horsecars, which were widely used in urban areas before electrification. Tram lines may also run between cities and/or towns (for example, interurbans, tram-train), and/or partially grade-separated even in the cities (light rail). Trams very occasionally also carry freight.
