How Poland Is Rewiring Rail for a High-Speed, Green Future

Poland is rapidly emerging as a Central European test bed for the future of rail, combining high-speed links, new-generation trains and low-emission technologies to connect its cities faster and more sustainably.

High-Speed Ambitions Reshape the National Map

Poland’s rail modernisation push is anchored in a new generation of fast intercity services designed to compete with highways and short-haul flights. Existing upgraded main lines already allow services such as Pendolino trains to run at up to 200 km/h on key north–south and east–west corridors, sharply cutting journey times between hubs including Warsaw, Gdańsk, Kraków and Katowice.

Publicly available information on the Warsaw–Gdańsk line shows how transformative these upgrades have been. After track renewal, curve realignments and modern signalling, travel times on the 323 kilometre corridor fell from around six hours to under three, bringing two of Poland’s most important economic and tourist centres within easy rail reach of each other. Similar improvements are being pursued on other strategic routes that form the backbone of the national network.

At the heart of future plans is the Centralny Port Komunikacyjny, or Central Transport Hub, a vast airport and rail project west of Warsaw. Government documentation on the CPK multi-year programme indicates that it includes a web of new “Y-shaped” high-speed lines radiating from the hub toward Łódź, Poznań, Wrocław, Kraków and the Silesian region. Early works, including a high-speed tunnel under Łódź, are now among the country’s most advanced rail investments, signalling that fast intercity links are moving from vision to construction.

In parallel, recent coverage of a national tender for trains capable of up to 320 km/h points to ambitions that go beyond today’s upgraded conventional lines. The call for 20 high-speed sets to operate between Warsaw, Łódź, Poznań and Szczecin, with potential extensions to Berlin, suggests that Poland aims to anchor itself firmly in Europe’s emerging high-speed rail grid.

New Trains Bring Comfort, Capacity and Speed

Track upgrades are being matched by a rolling stock renewal on a scale not seen in Poland for decades. Reports on fleet investment show that PKP Intercity and regional operators have ordered large numbers of modern multiple units and coaches, often co-financed by European Union funds. These trains are designed to run at higher speeds, offer better accessibility and provide passengers with a more predictable, airline-style experience.

One of the most striking recent developments is the decision by the national operator to purchase 42 double-decker trains in what has been described as the largest rolling stock contract in Polish rail history. According to industry coverage, the sets will be built domestically and certified for speeds up to 200 km/h, each offering more than 500 seats. For heavily used routes into Warsaw and other large cities, the additional capacity is expected to relieve crowding without requiring longer platforms.

Manufacturers with large footprints in Poland are expanding to meet that demand. Alstom announced in 2024 and 2025 that it is investing nearly 500 million złoty over five years to expand rolling stock production sites in Świętochłowice and Chorzów, where regional and metro trains for both domestic and export markets are produced. Company statements indicate that new halls and upgraded facilities are intended to support more advanced, energy-efficient train platforms.

Regional operators are following a similar path. A framework agreement reported in mid 2024 covers up to 50 additional FLIRT electric multiple units for use in Polish regions, again backed by recovery and resilience funding. These trains are planned to improve comfort, provide better on-board information systems and shorten travel times on busy commuter and regional corridors feeding into the main intercity network.

Digital Signalling and Infrastructure Upgrades Boost Reliability

Behind the headline-grabbing trains, Poland is investing heavily in the less visible systems that enable higher speeds and more frequent services. Infrastructure manager PKP PLK is rolling out the European Rail Traffic Management System, particularly ERTMS Level 2, on core corridors. This standard, already adopted in several Western European countries, allows continuous communication between trains and control centres, supporting safer operation at higher speeds and improving capacity on busy lines.

A central maintenance agreement signed in 2024 between PKP PLK and Alstom covers the upkeep of signalling equipment, including point machines, across a growing part of the network. The arrangement is described in company releases as the first such centralised service contract in Poland focused on ERTMS technology, and is intended to ensure that sophisticated digital systems remain reliable as traffic grows.

Urban bottlenecks are also being tackled. Project documentation for works on the Warsaw ring railway outlines a programme of track renewal, station modernisation and capacity enhancements on about 20 kilometres of line around the capital. These upgrades are designed to separate fast intercity trains from suburban traffic, reduce conflicts at junctions and improve resilience on a corridor that links Poland’s north–south and east–west routes.

Construction of the high-speed tunnel under Łódź, part of the broader CPK scheme, illustrates how infrastructure projects are being used to shorten routes and simplify operations. The tunnel will allow long-distance trains to pass under the city and connect with new high-speed alignments, cutting journey times between Warsaw and western Poland and freeing up surface tracks for regional and freight services.

Hydrogen, Biofuels and a Greener Rail Future

As it modernises, Poland is also turning its rail network into a platform for low-carbon technologies. Conventional electrification remains the backbone of decarbonisation, but recent pilot projects suggest that policymakers and operators see hydrogen and advanced biofuels as important complements, especially on lines where electrification would be costly or slow to deliver.

In September 2025, media focused on Silesia reported the launch of Poland’s first hydrogen-powered train in the heavily industrialised region. The locomotive, developed with domestic manufacturer PESA and energy group Orlen, is being tested on non-electrified routes that still rely on diesel traction. Observers note that for a region long associated with coal, the shift toward hydrogen-powered rail has strong symbolic and practical significance.

Hydrogen-related initiatives extend beyond rolling stock. Coverage in specialist energy outlets highlights the construction of a hydrogen production plant in Upper Silesia and the H2Silesia green hydrogen project, aimed at supplying industry and transport. Pilot refuelling stations have opened in cities such as Poznań and Katowice, creating the backbone of an emerging hydrogen corridor that rail operators may be able to tap as fleets evolve.

Regions such as Mazovia and Lower Silesia are also experimenting with low-emission biofuel trains. Reports from 2024 describe contracts for modern multiple units using biofuel-compatible engines, to be delivered before the end of the decade. These trains are presented as a transitional solution that can cut emissions on rural and regional routes while plans for full electrification, hydrogen deployment or battery trains are refined.

What Travelers Can Expect on Poland’s Trains

For travelers, the combined effect of these initiatives is already visible on some of Poland’s busiest routes and is likely to become more noticeable over the next decade. On upgraded main lines, modern intercity trains now offer shorter journey times, air-conditioned carriages, power outlets and on-board Wi-Fi, making rail a more competitive option against domestic flights and long-distance buses.

New double-decker sets and expanded fleets of electric multiple units should improve the experience on peak-time and regional services by increasing the number of seats and reducing reliance on older carriages. As digital signalling systems mature, passengers may also see more punctual operations and clearer real-time information, particularly on complex corridors around Warsaw and other major junctions.

The spread of low-emission technologies, from hydrogen locomotives in Silesia to biofuel-powered trains in selected regions, remains at an early stage but is already reshaping the image of rail in a country historically tied to coal. For international visitors, these developments mean that journeys between cities such as Warsaw, Kraków, Gdańsk and Wrocław are set to become not only faster and more comfortable but also significantly cleaner in climate terms.

While questions remain about long-term funding and the final shape of the CPK high-speed network, Poland’s current pipeline of projects suggests that rail will play a central role in connecting its rapidly growing cities. For travellers planning to explore the country, keeping an eye on new routes, faster services and greener trains could open up fresh possibilities for low-carbon trips across Central Europe’s largest emerging rail market.
