Line 2 (Green) of the Rio de Janeiro Metro serves working-class residential neighborhoods extending toward the north. It is a diagonal line, and almost completely above ground (mostly at graded and partly elevated). This line started as a light rail line, but for increasing commuters, it gradually changed to metro standards.[1] Due to its origin as light rail, it is at-grade except for Estácio station, although Cidade Nova station will be elevated.
