Which mode of transport runs on tracks in many urban areas?

Explanation

A tram is a passenger rail vehicle which runs on tracks along public urban streets and also sometimes on separate rights of way. Trams are used as public transport in many cities, transporting people from one stop to the next. The first trams were pulled by horses. The very first tram was on the Swansea and Mumbles Railway in south Wales. It started operating in 1807.
