The first Line 4 train rolled out of CNR Changchun's factory in September 2014.

BRAZIL: Communications project leader ENG has selected Kapsch CarrierCom to implement a Tetra digital radio network for Rio de Janeiro metro Line 4.

Kapsch is to provide four base stations, 140 handheld portable radios and 30 in-train cab radios for the fleet of 15 six-car trainsets, which CNR Changchun is supplying.

Running from General Osório to Jardim Oceánico, with a branch to Gávea, the 16 km Line 4 is due to open in the first half of 2016, in time for the Olympic Games taking place in Rio that year. Deliveries of the 15 trainsets are due to be completed by June 2015.
