Polský hybrid. Newag ukázal jízdu první hybridní jednotky, která vrátí dálkové spoje do 14 měst – Zdopravy.cz

Newag has completed the first test run of a hybrid passenger train unit designed for PKP Intercity, the primary long-distance rail operator in Poland. This development allows high-standard long-distance rail services to operate on both electrified and non-electrified tracks, removing the need for passengers to change trains or for operators to switch locomotives at the end of electrified sections.

The deployment of these hybrid units is part of a strategic initiative to restore long-distance connections to 14 Polish cities that currently lack the overhead electrification required for standard electric trains. By utilizing a hybrid propulsion system, PKP Intercity can extend its reach into regional hubs without waiting for the completion of large-scale infrastructure electrification projects.

Hybrid Propulsion and Operational Efficiency

Hybrid rail units, often categorized as Battery Electric Multiple Units (BEMUs) or diesel-electric hybrids, integrate two different power sources to maintain traction. In the case of the Newag unit, the system allows the train to draw power from the overhead catenary lines while on electrified sections and switch to an internal energy source—such as batteries or a high-efficiency internal combustion engine—when entering non-electrified zones.

This transition is designed to be seamless, ensuring that travel times are not significantly impacted by the change in power mode. The primary technical advantage is the reduction of the traction gap, where long-distance trains typically terminate at the edge of the electrified network, forcing passengers to transfer to slower, diesel-powered regional trains for the final leg of their journey.

According to reporting from Zdopravy.cz, the successful test run validates the unit’s ability to handle the specific load and speed requirements of long-distance transport, which are more demanding than those of short-haul regional commutes.

Expanding the Long-Distance Network

The decision to target 14 specific cities is based on a need to improve connectivity in regions where the cost or geographic difficulty of installing overhead wires makes full electrification impractical in the short term. By deploying hybrid units, PKP Intercity can offer a consistent level of comfort and speed across the entire route, regardless of the track’s electrical status.

The integration of these units is expected to increase the frequency of services to these cities and potentially attract more passengers away from road transport. The ability to use a single train set for the entire journey reduces operational complexity and minimizes the time lost during locomotive swaps at transit stations.

Industry and Environmental Context

The shift toward hybrid units reflects a broader trend in European rail technology to move away from pure diesel traction. While full electrification is the ultimate goal for carbon neutrality, hybrid technology serves as a critical transitional tool. It allows for an immediate reduction in emissions compared to traditional diesel locomotives while providing the flexibility needed for diverse infrastructure states.

Newag is positioning this hybrid technology as a solution for operators facing similar infrastructure challenges across Central and Eastern Europe. The ability to maintain high-speed long-distance standards on mixed-power lines provides a competitive edge over traditional diesel-only fleets, which often suffer from lower acceleration and higher noise levels.

The technical specifications of the Newag unit focus on energy recovery, where braking energy is captured and stored to be used during the non-electrified portions of the trip, further increasing the efficiency of the onboard power system.

Implementation Timeline

Following the successful test run demonstrated on May 9, 2026, the units will undergo further certification and safety testing to ensure they meet all national and European rail safety standards. Once certified, PKP Intercity will begin the phased introduction of these trains into active service on the identified routes to the 14 target cities.

The rollout is expected to occur in stages, prioritizing the routes with the highest passenger volume and the most significant gaps in electrification. This approach allows the operator to monitor the performance of the hybrid systems under real-world conditions before expanding the fleet.
