The remaining 14 sets are due to be delivered by the end of this year and following commissioning the fleet will initially be used on metro lines 1 and 2 before entering service on the new line, which is due to open in time for the Olympic Games next August.

The 16km six-station Line 4 will link Jardim Oceânico in Barra da Tijuca with Nossa Senhora da Paz in Ipanema and will serve the Olympic Village with a journey time of 15 minutes between the two termini.
