With over 14,000 units, Tatra T3 is the most widely produced type in history.
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which vehicles, whether individual railcars or multiple-unittrains, run on tramway tracks on urban public streets; some include segments on segregated right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term light rail, which also includes systems separated from other traffic.
Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city streets and diesel in more rural environments. Occasionally, trams also carry freight. Some trams, known as tram-trains, may have segments that run on mainline railway tracks, similar to interurban systems. The differences between these modes of rail transport are often indistinct, and systems may combine multiple features. (Full article...)

The Eurocopter AS 350 Ecureuil ("Squirrel") and AS 355 Ecureuil 2 are a family of light helicopters originally manufactured by Aérospatiale (now part of Eurocopter Group). The AS 350 (marketed as the AStar in North America) is the single-engined version, while the AS 355 (TwinStar) uses two engines. The EC 130B is a recent adaptation of the AS 350 airframe.
