Metro are a mass rapid transit system inside a city. It can be underground, elevated or at grade, so don't get fooled by an elevated metro, like in Bangkok, Chicago? Or at grade like in London suburb. Trams are light rail vehicles, often sharing tracks with cars.

No, a tram is not a metro, although they both fall under the category of urban rail transit. The primary difference lies in the "right-of-way" and capacity. A tram (also known as a streetcar or trolley) typically operates on tracks laid within public streets, often sharing the road with cars, buses, and pedestrians. Trams stop frequently and are integrated into the streetscape, making them ideal for short-distance city travel. In contrast, a metro (also known as a subway, underground, or U-Bahn) is a high-capacity "rapid transit" system that is entirely "grade-separated." This means it operates on its own dedicated tracks, usually in tunnels underground or on elevated structures, completely isolated from street traffic. This allows metros to travel at much higher speeds and carry significantly more passengers over longer distances. There is a middle ground known as "Light Rail Transit" (LRT), which uses tram-like vehicles but often has its own dedicated lanes or tunnels, blurring the line between the two, but in a strict technical sense, the shared-street nature of a tram separates it from the heavy-duty, isolated metro system.
