Like many other cities in Brazil, Rio de Janeiro is a sprawling metropolis with a public transit network that does not truly support the needs of the city. Despite having a population of over 6 million people, the city relies on a bus network with over 400 lines as its primary form of public transportation. There is a small, two line subway that serves a limited part of the city, with plans to construct a third line. There is also a commuter rail system, the SuperVia, which has 8 lines and 100 stations. Rio is home to Latin America’s oldest electric railway of any kind, the Santa Teresa Tram, but it has been suspended since 2011 with only limited service since 2015 due to a fatal accident.
The Santa Teresa Tram is a historic tram line connecting downtown Rio de Janeiro to the Santa Teresa neighborhood along a a 3.7 mile long route. It ran continuously from 1877 until 2011 and was electrified in 1896, making it the oldest electric railway of any kind in Latin America. It was Rio's only tram line after 1967; the city had an extensive tram network prior to then. Service was suspended in 2011 following a serious, fatal accident. As of July 2015, limited service has been restored along the line.
