Line 3, which will be 22.1km long and have 18 stations, will run from Américo Vespucio to Tobalaba/Larrain. The 15.3km Line 6 will have 10 stations and will connect Pedro Aguirre Cerda with Los Leones.
Systra's technical assistance will cover all systems and rolling stock for the new lines, and will be divided in two phases. During the first phase, which will last for around a year, Systra will conduct the basic design for the two lines. The second five-year phase encompasses assistance with awarding of contracts, review of construction design studies, supervision of works, testing and assistance with commissioning.
Systra will establish a staff of 10 people in Santiago to work on the project, with more than 45 people involved in the contract. Systra has assisted Santiago Metro with design and construction of Chilean capital's entire metro network since it was first conceived in the 1960s.
