Streetcars attract wealthier riders than buses and inspire new, high-density property development. Over a dozen municipalities around the world have restarted and extended streetcar lines. And some 50 cities in the United States are planning new lines.

About a quarter of the total cost of streetcar rail construction goes toward installing the power lines.
