History and features
The consortium winner of the Line 4 concession was ViaQuatro, who had to obey the public-private partnership bid that projected the trains must have standard gauge, instead of broad gauge present on Lines 1, 2 and 3 and overhead lines like on Line 5 and CPTM lines. The voltage is of 1,500 V. In March 2010, 5 of the 14 initial units were already in tests on the line.[2]
The compositions, built in South Korea, have the driverless system, the first in Latin America, which allows the operation of the train without a driver.[3] The cars are all interconnected by articulated corridors and also have air conditioning system. Initially, it was estimated that they would have cell phone signal and wireless internet access,[3] but the Wi-Fi propposal was discarded and the cellular connection took months to be available on the line.
The trains have emergency exits on the front and back of the compositions,[3] where the front mask bends down, opening the way and creating a ramp for passagers to disembark and walk on the tracks until the next station. Also because of that, the space between tracks was unobstructed, to avoid accidents in case of evacuation. Besides that, there are side walkways on the tunnels between stations, just like other metro lines. Therefore, so the passengers in B cars can leave, they use the free gangway. In the A cars, there are 2 windows where passengers can have a view from the tracks, an angle not available in other lines of the system, with the exception of Line 15-Silver.
