Poland has completed the installation and commissioning of a European Rail Traffic Management System (ERTMS) Level 2 signalling system on a core high-speed corridor, marking a pivotal advance in the country’s long-term rail modernisation strategy and opening the door to higher operating speeds and closer integration with the wider European rail network.

A Milestone for Poland’s High-Speed Ambitions

Publicly available technical and regulatory information indicates that the completed ERTMS Level 2 deployment is focused on a section of the Central Trunk Line, a key north–south high-speed axis in Poland that already hosts 200 km/h Pendolino services. The new radio-based signalling layer replaces reliance on lineside signals for continuous train supervision and is designed to support higher speeds once accompanying infrastructure upgrades are finalised.

The Central Trunk Line has been a showcase for Poland’s high-speed aspirations for more than a decade, with successive infrastructure works funded in large part through European Union cohesion and transport programmes. Earlier stages included track renewal, power supply upgrades and the introduction of ERTMS Level 1, which allowed faster services but still relied on intermittent information transfer to trains. With Level 2 now commissioned, the corridor aligns more closely with the standards used on many of Europe’s flagship high-speed routes.

According to sector analyses and industry coverage, the latest signalling works on the corridor form part of a wider investment portfolio coordinated by PKP Polskie Linie Kolejowe, the national infrastructure manager. This portfolio is intended to prepare the network for sustained operation at up to 230 to 250 km/h on selected stretches, subject to rolling stock approvals and safety validation.

Recent regulatory documentation confirms that PKP Polskie Linie Kolejowe has obtained renewed safety authorisation to manage infrastructure designed for speeds up to 250 km/h on core routes, including the Central Trunk Line. That authorisation, coupled with the completed ERTMS Level 2 deployment, establishes the formal framework under which faster regular passenger services can be introduced in the coming years.

How ERTMS Level 2 Transforms Operations

ERTMS Level 2 is a digital, radio-based signalling system in which movement authorities and speed profiles are transmitted continuously from Radio Block Centres to trains equipped with onboard European Train Control System equipment. Technical factsheets from the European rail sector describe how this architecture allows trains to receive real-time updates on permitted speed and route status directly in the cab, significantly reducing dependence on wayside signals.

For the upgraded Polish high-speed line, this means that drivers receive continuous information on track conditions, gradients, temporary speed restrictions and the position of other trains ahead. If a train exceeds the permitted speed or approaches a stop signal, the onboard system can automatically apply the brakes, enhancing safety compared with older national systems based on intermittent control.

Another important consequence of Level 2 deployment is improved capacity. Because the system continuously supervises train movements and can reduce the headway between trains while maintaining safety margins, more services can be scheduled on the same piece of infrastructure. For an already busy intercity corridor like the Central Trunk Line, this is expected to help accommodate forecast growth in passenger demand without the need to build entirely new parallel tracks.

From an interoperability perspective, the completed installation supports cross-border and pan-European operations by aligning the Polish high-speed corridor with the common ERTMS standard used on high-speed routes in countries such as Spain, Italy and France. Rolling stock fleets designed for ERTMS can in principle operate seamlessly across multiple national networks, reducing technical barriers that previously limited international services.

Integration with Wider Network Upgrades

The completion of ERTMS Level 2 on the Polish high-speed line is one element in a multi-corridor deployment strategy that extends across several major routes. European Commission deployment overviews describe how parts of the Warsaw–Gdańsk–Gdynia line, the E30 corridor and other strategic axes have already been equipped with modern signalling, with further tenders covering lines such as Warsaw–Radom and sections of the planned Central Communication Port access routes.

In practice, this means that Poland is moving from pilot projects and isolated high-speed segments toward a more continuous network of lines equipped with ERTMS. The newly completed installation on the high-speed corridor helps to close gaps between existing ERTMS-equipped sections, offering more consistent performance for long-distance services and reducing the need for trains to switch between different protection systems en route.

Industry reports highlight that suppliers active in the Polish market have now implemented ERTMS technology across well over a thousand kilometres of track, ranging from conventional main lines to upgraded high-speed routes. The Central Trunk Line installation is seen as particularly significant because of its role within the trans-European transport network and its connection to other upgrade projects around Warsaw and southern Poland.

The completed Level 2 deployment also dovetails with work on new high-speed infrastructure that will eventually connect Warsaw to Łódź, Wrocław and Poznań. While those new-build high-speed sections are still several years from opening, the existence of a functioning Level 2 core on the legacy network provides a testbed and reference point for the next generation of lines that are expected to be ERTMS-equipped from the outset.

Passenger Benefits and Future Speed Increases

For passengers, the most visible benefit of the completed ERTMS Level 2 installation is likely to be shorter and more reliable journey times on flagship intercity services linking Warsaw with major cities in the south of the country. Earlier upgrades on other Polish corridors equipped with ERTMS reduced end-to-end travel times by more than two hours in some cases, and observers expect similar incremental gains as timetables are recast on the Central Trunk Line.

In the near term, operators are expected to focus on using the new system to stabilise punctuality and make better use of the existing 200 km/h speed envelope. Over time, as infrastructure owners complete associated civil works and level crossing removals, and as rolling stock receives the necessary authorisations, the corridor is positioned to support routine 230 km/h operation, with the technical potential for 250 km/h on selected stretches.

Improved reliability is another major benefit. With continuous train supervision and automatic enforcement of speed and signal observance, the scope for human error is reduced. The system also enables more precise monitoring of train performance and infrastructure status, providing infrastructure managers with better data for maintenance planning and incident response.

From a passenger-experience perspective, higher frequencies and more dependable journey times on the upgraded line are expected to reinforce the competitiveness of rail against road and domestic air travel, particularly on medium-distance city pairs where door-to-door times are already comparable. This aligns with broader European and national objectives to shift more travel to lower-emission modes.

Financing, Timelines and Next Steps

The completed ERTMS Level 2 installation is part of a broader investment cycle in Polish rail, financed through a mix of national funds and European mechanisms such as the Connecting Europe Facility and cohesion policy instruments. Project documentation for earlier stages on similar corridors shows that ERTMS deployments typically form one component of integrated upgrade packages including track, catenary, bridges and stations.

Rollout on the high-speed line has been phased to minimise disruption to existing services, with signalling commissioning often scheduled during overnight or low-traffic windows. Reports on earlier ERTMS introductions in Poland indicate that extensive test campaigns at line speed were undertaken with modern intercity trainsets before authorising the start of commercial operation under Level 2 supervision.

With commissioning now complete on this core section, attention is expected to shift to extending Level 2 coverage further along the corridor and to other strategic lines feeding into the same high-speed spine. Sector roadmaps suggest that Poland’s objective is to have a continuous chain of ERTMS-equipped routes along key trans-European corridors within the next decade, creating a high-capacity backbone for both passenger and freight services.

As additional projects move from design to construction, the completed installation on the Polish high-speed line serves as both a reference project and an operational laboratory, illustrating how ERTMS Level 2 can be integrated into an existing network while preparing the ground for future, purpose-built high-speed rail.
