Tram

A tram (tramcar, trolley, or streetcar) is a passenger vehicle that is like a light train. It carries people to places within a city. Because a single tram can carry many people at the same time, riding on a tram instead of driving a car is a good way to help prevent pollution and stop the roads getting too busy.

The word tram is used mainly outside North America, while within North America these vehicles are called streetcars or trolleys as they run mainly on streets.

More modern and larger trams manufactured since the 1970s, such as the one in the second picture from Warsaw, are called light rail vehicles. These vehicles are bigger because they are very often made of two or more parts, with a bendy section in the middle which works like a human joint. In railway jargon, these types of vehicles are called "articulated". These may sometimes have their own right-of-way instead of traveling on the street and their stops are usually farther apart than the stops of trams so that they can travel faster.

On Market Street in San Francisco, vintage streetcars from the 1910s through the 1940s, called "historic streetcars" (the F Market line), that travel on the street are a popular tourist attraction. Another city whose trams are highly used by tourists is Hong Kong, because here the trams have two floors which is very rare in the world.

The largest tram networks in the world are in: Melbourne, St. Petersburg, Amsterdam, Berlin, Moscow and Vienna.
