Project Update

Lisbon Metrorail Project, Portugal [free access]

January 1, 2022

Key player: Metropolitano de Lisboa (ML) is the system developer and operator.


Project description: Expansion of the existing metro rail system and deployment of 42 rail cars and automatic train control (ATC) system.


Background: The system comprises four lines that together span 44.3 km and cover 56 stations. These are:


- Linha Azul (Blue), which spans 13.8 km from Santa Apolónia to Reboleira, covering 18 stations.


- Linha Amarela (Yellow), which spans 11 km from Rato to Odivelas, covering 13 stations.


- Linha Verde (Green), which spans 9 km from Cais do Sodré to Telheiras, covering 13 stations.


- Linha Vermelha (Red), which spans 10.5 km from São Sebastião to Aeroporto, covering 12 stations.


There are six transfer stations.


Ridership: The annual ridership is 90.6 million (2020).


Rolling stock and signalling system: A consortium of Stadler Valencia and Siemens Mobility Unipessoal has secured a contract to supply 14 three-car trains and the communication-based train control (CBTC) signalling system. The contract also includes a provision for preventive and corrective maintenance of all equipment for a period of three years, with an option for an extension for an additional two years. The contract value is around EUR114.5 million. In May 2021, Portugal’s Court of Auditors granted approval for the contract.


Stadler will be responsible for supplying the rolling stock, while Siemens will provide the CBTC system. A fleet of 70 trains will be installed with the automatic and continuous control system. The Blue, Yellow, and Green lines will be equipped with automatic train protection (ATP), automatic train operation (ATO), and automatic train supervision (ATS). The contract period is around 77 months. The first train is expected to be delivered by 2023 for testing.


Track and power supply: Tracks are standard gauge (1,435 mm). Power is sourced from the third rail (750V DC).


Fare system: Contactless smartcards and bankcards are used as fare media. The fare system is integrated across all modes of public transportation in the city.


Extensions/Capital projects: ML is undertaking the following projects for the expansion of the system:


- Circular Line: It will comprise a 2-km long tunnel connecting the Cais do Sodré terminus station of the Green Line with the Rato terminus station of the Yellow Line. The project involves the construction of two stations – Estrela and Santos. The project will be constructed in two sections: section 1, from Rato station to Santos station; and section 2, from Santos to Cais de Sodré. The extension will create a new circular line through the city centre, with six-car trains travelling at a frequency of 3 minutes and 40 seconds during peak hours.


Portugal-based Zagope-Construções e Engenharia has secured the EUR48.62-million contract to construct the line.


Construction is expected to be completed by 2024 at an investment of EUR216 million. Of the total investment, EUR83 million will be funded from the European Union (EU) budget under the Operational Programme for Sustainability and Efficiency in the Use of Resources.


- Red Line extension: It will span 4 km from São Sebastião to Alcântara, with three underground stations at Amoreiras, Campo de Ourique, and Infante Santo, and a surface station in Alcântara. The scope of work will also cover the construction of 380 metres of viaducts. ML completed the preliminary feasibility study and submitted the licensing process documents to the Portuguese Environment Agency (APA) in December 2021.


In October 2021, Recuperar Portugal, the body overseeing the country’s COVID-19 Recovery and Resilience Plan 2026 (PRR), signed an agreement with Lisbon Metro to grant EUR304 million for extension. The funding for the project is conditional on its being completed by December 31, 2025.


The annual ridership on the extension is expected to be 11 million passengers.
