Alstom secures a historic rail project in Portugal in 2026

Alstom won a €1,03 billion contract in 2026 from Comboios de Portugal, the state-owned company responsible for passenger rail transport. The French group will supply 153 Adessia Stream trains to modernize the country's regional and suburban rail services.

This order represents the largest train acquisition in Portugal's history. An initial contract for 117 trainsets was signed in October 2025, before being supplemented by an order for 36 additional units. The first trains are expected to enter service from 2029.

Trains adapted to the needs of Portuguese travelers

The future fleet will comprise 98 trains for the suburban networks of Lisbon, Porto, and Cascais. The remaining 55 trains will operate on regional lines. Each train will consist of three cars and will be able to carry up to 450 passengers.

The trains will have step-free access and a flat floor along their entire length. They will also offer Wi-Fi access and dedicated spaces for wheelchairs and bicycles. Accessibility organizations participated in the design process to better meet the needs of passengers.

A new railway factory in Portugal

To fulfill this order, Alstom will build a factory of over 20,000 square meters in Matosinhos, in the Porto region. This new site will handle part of the train manufacturing in partnership with the Portuguese public works company DST.

Nearly 300 direct jobs are to be created in the fields of engineering, production, and technical trades. Fifteen percent of these positions will be reserved for unemployed youth, the long-term unemployed, and people with disabilities or health problems.

An industrial and environmental investment

The new trains were developed according to eco-design principles that take into account their entire life cycle. Alstom notably announces a recyclability rate of over 95%, as well as digital systems designed to reduce energy consumption and facilitate maintenance operations.

This contract significantly strengthens Alstom's presence in Portugal, where the manufacturer has been established for over thirty years. Two out of every three trains operating in the country were already manufactured by the group or use some of its technologies. The project should now allow Portugal to renew its aging rolling stock while developing a genuine national rail production capacity.
