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 Glacier Express from Zermatt to St. Moritz (or Davos Platz [Summer only]) in Switzerland is one of the great train journeys in the world. It is not an "express" in the sense of being a high-speed train (it isn't) but rather in the sense that it provides a one-seat ride from end to end, even though the train travels over several different railroad lines; reputedly it is the slowest "express" in the world. The trip on the Glacier Express is a 7½ hour railway journey across 291 bridges, through 91 tunnels and across the Oberalp Pass at 2,033 metres in altitude. The entire line is metre gauge, and large portions of it use a rack-and-pinion system both for ascending steep grades and to control the descent of the train on the back side of those grades.
