Bulgaria’s suburban and regional rail network has officially welcomed its first modern electric multiple units into passenger service, according to the Ministry of Transport and Communications of the Republic of Bulgaria. Commuters traveling on regional routes are now riding aboard the newly introduced BDZ Class 34 trains, marking a tangible upgrade for the national carrier’s rolling stock fleet.
BDZ Class 34 Rollout and Infrastructure Approval
The transition from testing to active passenger operations followed a strict regulatory timeline overseen by state authorities. According to the Ministry of Transport and Communications, all 20 units ordered for suburban and regional transport were successfully handed over to the customer by August 5. Following physical handovers, the trains underwent rigorous testing on local infrastructure to ensure compatibility with national rail systems.
Upon completing infrastructure trials, the trains secured essential statutory clearances. According to official disclosures, the units received type approval and APOM authorization from the Bulgarian agency RAEA. Shortly thereafter, on August 7, all RegioPanters were officially registered in the European Vehicle Register (EVR), granting them permanent legal authorization to operate across the territory of Bulgaria.
Technical Specifications and ETCS Level 2 Integration
Engineered for high-capacity regional transit, the newly deployed railcars boast advanced engineering parameters. According to technical documentation, the 25 kV RegioPanters are built to reach a maximum speed of 160 km/h. To meet modern European rail interoperability and safety standards, the trains are outfitted with the AURIGA ETCS Level 2 OBU from CAF Signalling.
Preparation for regular public timetables began immediately following EVR registration. According to transit authorities, operators initiated targeted preparation runs starting August 10, which included operating selected Class 34s without passengers on selected lines to iron out operational nuances before full public integration.
Did you know? The European Vehicle Register (EVR) serves as a centralized database that assigns a unique European Vehicle Number to rail vehicles, ensuring cross-border traceability and regulatory compliance across participating EU member states.
Future Expansion and Comprehensive Maintenance Contracts
The initial 20-train fleet acquisition is set to grow following supplemental agreements finalized late last year. An agreement for five additional RegioPanters was concluded between the Bulgarian Ministry of Transport and Škoda Group in November 2024, building upon an option from the September 2024 primary agreement, with manufacturing slated to begin shortly.
Beyond vehicle delivery, the partnership includes long-term technical support to ensure high fleet availability. The contract also includes 15 years of comprehensive service, which the manufacturer will provide directly in Bulgaria.
