The metro operates through a system of interconnected lines that share certain sections of track.

The system uses modern trains, such as those manufactured by CRRC, to handle high passenger volumes. These specific trains can carry up to 2,240 people at a single time. They are designed to reach a top speed of 80 kilometers per hour. Because Rio de Janeiro can be very hot, these trains are equipped with air conditioning units. These units allow the trains to operate effectively even in temperatures as high as 40 degrees Celsius. The fleet includes many of these advanced cars to ensure frequent service.
