# Río de Janeiro Metro

The Rio de Janeiro metro is a massive underground railway network that serves the city of Rio de Janeiro, Brazil. Opened in 1979 with a single line and five stations, today it includes 41 stations, 57 kilometers of operational routes and three lines (Line 1 Orange, Line 2 Green and Line 4 Yellow) that carry approximately 1 million passengers per day.

In 2016, on the occasion of the celebration of the Olympic Games in the city, Line 4 was launched, as an extension of Line 1 connecting Ipanema and Barra da Tijuca. The final project proposes six new stations connected to each other through communication, transport and security systems that work with stability and coordinately.

Line 4 (Metro Barra) of the Rio de Janeiro metro has EN-54 certified public address and voice evacuation systems in its facilities.
