The project involves the construction of the line from Tirol-Moura Brazil to Papicú beyond which the depot will be located, and includes 7.3km of tunnelling.


Phase one includes underground stations at Central Chico da Silva, Colegio Militar, Nunes Valente and Papicú, and one ground-level station at Tirol-Moura Brazil.

Strengthening work in the tunnels will also be carried out in preparation for the construction of Catedral and Luiza Távora stations in later phases.
