A traditional form of public transport in Lisbon is the tram. Originally introduced in the 19th century, the trams were originally imported from the U.S. and called americanos. The Lisbon tramway system still employs small (four wheel) vehicles of a design dating from the early part of the twentieth century. These distinctive yellow trams are one of the tourist icons of modern Lisbon, and their size is well suited to the steep hills and narrow streets of the central city.
