Portugal Ups Alstom Fleet Order to over 150 Units in Country’s ‘Biggest Ever Train Investment’

Why It Matters

Accelerating Portugal’s rail modernisation improves capacity, reduces reliance on outdated rolling stock, and positions the country as a hub for European train manufacturing.

Key Takeaways

• Order increased to 153 Alstom Adessia Stream EMUs.
• Investment rises to €1.064 billion, €318 million extra.
• Delivery timeline accelerated to 2029‑2031.
• New domestic manufacturing hub creates ~300 jobs.
• Fleet renewal will cover >40% of CP’s rolling stock.

Pulse Analysis

Portugal’s decision to expand its Alstom‑DST rolling‑stock contract marks the largest train procurement in the nation’s recent history. By raising the order to 153 Adessia Stream electric multiple units, the government pushes the total spend past the €1 billion threshold, a figure that rivals similar programmes in Spain and Italy. The move aligns with the EU’s Green Deal objectives, as electrified commuter services replace diesel‑powered stock and help cut carbon emissions. Moreover, the accelerated delivery schedule—now set for 2029‑2031—demonstrates a political commitment to fast‑track infrastructure upgrades ahead of the 2030 climate targets.

For Comboios de Portugal, the additional 36 suburban units translate into a tangible capacity boost on the Lisbon‑Sintra and Porto‑Gaia corridors, where passenger volumes reached a record 208.2 million in 2025. Replacing a fleet with an average age of over 40 years will improve reliability, reduce maintenance costs, and enhance the passenger experience through modern amenities. The expanded order also means that more than 40 % of CP’s rolling stock will be renewed, positioning the operator to meet growing demand without resorting to costly interim solutions such as bus substitutions.

The ancillary benefit of the contract is the establishment of Alstom’s first assembly line in Matosinhos, projected to create roughly 300 skilled jobs and stimulate a domestic supply chain for components and subsystems. This industrial foothold could attract further European manufacturers, fostering a nascent Portuguese rail ecosystem that supports future high‑speed projects between Lisbon and Porto. By coupling fleet renewal with local production, the government not only secures operational resilience but also leverages the investment to drive broader economic diversification and export potential.
