What is a tram?

[OJocelyn]

Tram is a streetcar. The relevant introduction of tram is as follows: Introduction to tram: A tram (also known as streetcar or tramcar) is a light rail transit vehicle powered by electricity and running on tracks. It is a form of public transportation, also called a street tram, commonly referred to simply as a tram, and is a type of light rail. The train usually consists of no more than five cars. Modern tram: Compared to other motor vehicles, modern trams have fixed tracks, making them safer for pedestrians; they also produce fewer emissions, lower noise levels, and provide a better walking environment for pedestrians. Therefore, commercial districts often adopt a model where motor vehicles are prohibited, allowing only 'pedestrians + trams'.
