Alstom Delivers 35 Coradia Stream EMUs to BDZ Bulgaria

SOFIA, BULGARIA – Alstom has dispatched the first six-car Coradia Stream electric multiple units from its Bautzen plant in Germany to Bulgaria, marking the initial delivery of a 35-train order secured under a €720 million contract signed in 2025. This contract, executed by the BULEMU consortium of Alstom and RVP Invest, includes a €452 million fleet purchase and a €268 million long-term maintenance package. The 160 km/h regional trains represent Alstom’s first passenger rolling stock supply to the Bulgarian national operator BDZ.

What Does This Contract Cover?

The €720 million contract covers the manufacturing, delivery, and 15-year comprehensive maintenance of 35 six-car Coradia Stream electric multiple units (EMUs) designed for Bulgarian regional and intercity routes. The total transaction is split into a €452 million rolling stock acquisition and a €268 million maintenance services package, with Alstom’s individual share of the contract valued at €600 million. The remaining portion belongs to local partner RVP Invest, which will co-deliver preventive, scheduled, and emergency maintenance. The EMUs will operate on corridors up to five hours in duration, equipped with ERTMS Level 2 signalling, digital passenger counting, and multi-system power compatibility to align with European technical specifications for interoperability (TSI). The exact completion timeline for the remaining 34 train deliveries was not officially disclosed by the Bulgarian Ministry of Transport and Communications.

Key Contract Data

How Does This Compare to Similar Contracts?

The €268 million allocated for the 15-year maintenance of BDZ’s 35 EMUs highlights the lower lifecycle support costs of standardized passenger fleets compared to high-speed infrastructure maintenance packages. For instance, the UK’s High Speed 2 (HS2) project launched a market engagement exercise for a £1.24 billion (€1.45 billion) package of interim maintenance contracts (IMCs) covering a 10-year period from 2027 to 2037 (Source: Construction News, 2026). While the HS2 contracts cover complex civil assets and routine repairs before rail systems mobilization, the Bulgarian contract reflects a highly integrated rolling stock lifecycle model where maintenance is bundled directly with the €452 million manufacturing deal to minimize long-term operational risk for BDZ.

Editor’s Analysis

This procurement signals a shift in Southeast European rail strategy toward long-term fleet availability guarantees rather than simple asset procurement. By integrating ERTMS Level 2 technology directly from the German manufacturing base, BDZ aligns its network with Western European digitalization trends, which increasingly prioritize cybersecurity and data sovereignty (Source: IndexBox, 2025). This modernization establishes a critical baseline for Bulgaria to integrate into the wider European interoperable rail corridors.
