Alstom has broken ground on a new rolling stock assembly plant in Matosinhos, near Porto, marking a significant expansion of Portugal’s rail manufacturing capacity and anchoring a major train order for the national operator Comboios de Portugal.

Groundbreaking marks new industrial chapter for Portuguese rail

According to publicly available information, a groundbreaking ceremony held in late June 2026 in the Porto metropolitan area signalled the formal start of construction on Alstom’s new rolling stock facility. The site is located in Matosinhos, a coastal municipality just north of central Porto, in an area with existing transport and logistics infrastructure.

Reports indicate that the plant will cover more than 20,000 square metres and will be equipped with modern production technologies designed for commuter and regional train manufacturing. The layout is expected to include assembly halls, testing areas and supporting workshop functions tailored to electric multiple units.

Portuguese government communications describe the project as part of a wider strategy to place rail at the centre of national mobility policy. The facility is being framed as a symbol of reindustrialisation, bringing rolling stock production back into the country after decades in which most trains for the national network were imported or assembled abroad.

The groundbreaking also cements Alstom’s transition in Portugal from primarily a signalling and engineering supplier to a full-scale industrial actor, adding rolling stock assembly to an existing footprint that includes an engineering hub in Maia, opened in 2022.

Plant anchored by 153-train contract with Comboios de Portugal

The new factory is directly linked to a contract signed in March 2026 between Alstom and Comboios de Portugal (CP) for 153 new Adessia Stream trains, valued at around 1.03 billion euros. Publicly available corporate disclosures state that the order covers both suburban and regional units, aimed at renewing CP’s ageing fleet and expanding capacity on busy passenger corridors.

Project documentation indicates that the Matosinhos site will assemble the trains destined for the Portuguese network, tying local production to a long-term supply and maintenance programme. The contract is scheduled to be booked in Alstom’s 2025/26 financial year, aligning the factory’s ramp-up with the design and industrialisation phase of the new rolling stock platform.

Government notes and industry reports highlight that the first trains are expected to enter service toward the end of the decade, with communications from Lisbon pointing to a target of delivering the first “made in Portugal” train in 2029. The plant is therefore planned as a multi‑year industrial project rather than a short, project-specific assembly line.

By pairing a large domestic order with a new production base, the Portuguese authorities and Alstom are seeking to ensure that a significant share of the contract’s value remains in the national economy through jobs, supplier activity and tax revenues.

Jobs, skills and regional development in the Porto area

Official government communications on the project state that the Matosinhos plant is expected to create around 300 direct jobs once fully operational, with additional indirect employment anticipated across local supply chains and services. These positions are forecast to range from skilled production roles to engineering, quality control, logistics and plant management.

Local and national planning documents position the factory as a catalyst for an emerging rail and mobility cluster in the Porto region. With Alstom’s existing engineering centre in nearby Maia and ongoing signalling projects for Metro do Porto, the new industrial site consolidates northern Portugal as the company’s principal hub in the country.

Training and skills development are likely to be central to the plant’s early years. Publicly available information on Alstom’s other sites in Europe and Latin America indicates that new rolling stock facilities typically involve partnerships with technical schools, universities and vocational programmes to build expertise in welding, electrical integration, software, and testing.

Regional economic agencies present the investment as an opportunity to attract further suppliers in areas such as bogie components, interiors, cabling and digital systems, potentially reinforcing the Porto area’s role in European rail supply chains.

Supporting Portugal’s wider rail modernisation strategy

The launch of construction in Matosinhos coincides with a broader wave of rail investment in Portugal, which includes high-speed corridors, infrastructure upgrades and new rolling stock for both suburban and long-distance services. Government briefings describe the Alstom factory as one pillar of a national effort to expand capacity, improve service reliability and encourage modal shift from road and air to rail.

Earlier projects, such as the expansion of Porto’s metro network and signalling contracts awarded to Alstom for the city’s Pink Line, already underlined the company’s role in Portuguese urban mobility. The new manufacturing site extends that involvement from systems and engineering into domestic production of vehicles that will run on the mainline network.

Industry observers note that the investment also aligns with European policy priorities around strategic industrial capacity and resilient supply chains for clean transport. By hosting a modern rolling stock plant, Portugal positions itself as a contributor to regional efforts to decarbonise mobility through electrified rail services.

The plant’s design is expected to reflect prevailing sustainability standards in industrial construction, with publicly released material from Alstom on comparable projects elsewhere referencing energy-efficient buildings, optimised material flows and careful management of waste and emissions.

Alstom expands its global manufacturing footprint

The Matosinhos project fits into a pattern of recent investments by Alstom to expand or modernise rolling stock production sites in key markets. In recent years the company has invested in facilities in countries such as Poland, Brazil and South Africa, adding capacity close to major train contracts and domestic rail programmes.

Corporate communications emphasise that decentralised production enables Alstom to respond more quickly to regional requirements, adapt designs to local standards and regulations, and increase the share of local content in large orders. The Portuguese plant is being presented within that framework as a long-term base that will serve both CP and potentially other projects in Iberia and beyond.

Analysts following the rail sector point out that establishing a manufacturing presence in Portugal may also support future export opportunities, given the country’s Atlantic ports and links into European freight and logistics networks. While the immediate focus is on fulfilling the CP contract, observers suggest that the site could, over time, help Alstom compete for additional rolling stock tenders in the region.

With construction now underway, attention will turn to how quickly the Matosinhos facility can be built, equipped and staffed, and how it will integrate with Alstom’s wider European production system as Portugal prepares for a new generation of domestically assembled trains.
