  • Systems engineering and technological development will be managed at Alstom's recently opened site in Maia, Porto district.



15 November 2022 – Alstom, global leader in smart and sustainable mobility, has been awarded with Metro do Porto a contract to supply the signalling, safety and control systems for Metro Porto yellow line extension. Alstom will develop and equip the new line with signalling including a state-of-the-art interlocking, which will enable vehicles’ real time monitoring. The engineering, installation and commissioning of the system will be developed at Alstom's new site in Maia, Porto district.

The expansion of the yellow line runs from Santo Ovídio to Vila d'Este, in the south area of Porto, adding three new stations to the network, including an underground. The new 3,1 km route includes 500 metres of viaduct and 1,000 metres of tunnel. It is scheduled to come into service in the first half of 2024, representing a major improvement for urban mobility in the southern area of Porto.

"It is a great honour for Alstom to partner again with Metro do Porto, to improve mobility for citizens and tourists in Porto. We will develop this project from our new engineering facilities in Maia, where we lead signalling projects and digital mobility technologies for the Portuguese and international market."

David Torres
Alstom in Portugal Managing Director
