The route under study for the extension of MST line 3 will be 7.16 km long, including ten stations: Pêra, Várzea de Pêra (with connection to Funchalinho), Costa da Caparica Center, Costa da Caparica Urban Park, Santo António, São João, São Pedro, Madame Faber/Matas Nacionais, Bombeiros Voluntários da Trafaria and Estação Fluvial da Trafaria.
