 | | Trams are distinguishable from other forms of rail-borne vehicles in that they travel wholly or partly along tracks laid down in streets, usually on track reserved for the tram system. |
 | | The first trams, known as streetcars in north America, or horsecars, that were built in the United States, and developed from city stagecoach lines and omnibus lines that picked up and dropped off passengers on a regular route and without the need to be pre-hired. |
 | | Modern trams generally use overhead electric cables, from which they draw current through a pantograph, a bow collector (less commonly) or the now-rare trolley pole (the former is most common and used on most new tram designs). |
