Plovdiv-Burgas Railway Modernisation: Phase 2 Project Profile

The Phase 2 rehabilitation of the Plovdiv-Burgas railway line is a critical infrastructure project designed to elevate a key Bulgarian rail corridor to modern European standards. This project focuses on increasing operational speeds up to 160 km/h, enhancing safety through advanced signaling systems, and ensuring full interoperability within the Trans-European Transport Network (TEN-T).

Technical Specifications

The Plovdiv-Burgas line modernisation is a comprehensive engineering undertaking. A core component is the deployment of advanced signaling and control systems, including the European Train Control System (ETCS) Level 1 across 18 stations and the integration of a Global System for Mobile Communications – Railway (GSM-R). This digital upgrade is supported by the installation of new fiber optic cable infrastructure, ensuring reliable train control and communication. The project also implements a Supervisory Control and Data Acquisition (SCADA) system for centralised traffic management.

Civil engineering works include extensive track and catenary rehabilitation, the construction of a new tunnel, and the reconstruction of multiple bridges to support higher speeds and axle loads. A major safety enhancement is the systematic elimination of level crossings through the construction of new overpasses and underpasses. Modernisation extends to station infrastructure at key locations like Zavoy, Zimnitsa, and Straldzha, with a focus on improving layouts, platform accessibility for passengers with limited mobility, and operational efficiency. In the Chernograd-Aytos section, a protective forest belt is being established to mitigate operational disruptions from adverse weather.

Key Takeaways

• TEN-T Integration & Interoperability: As a vital segment of the TEN-T Orient/East-Mediterranean corridor, this upgrade aligns the line with EU standards. The implementation of ERTMS/ETCS is crucial for achieving seamless cross-border rail traffic for both passenger and freight services.
• Performance & Economic Gains: The project will increase maximum speeds to 160 km/h, cutting the Plovdiv-Burgas journey time by approximately 70 minutes. This enhancement makes rail a more competitive alternative to road transport, reduces operational costs, and stimulates regional economic activity.
• Sustainability & Safety Enhancements: The modernisation is projected to reduce annual CO₂ emissions by 35,000 tonnes, contributing to Bulgaria’s climate goals. Eliminating level crossings is expected to decrease incidents by over 40%, significantly improving safety for both rail and road users.
