Who will prepare the “heart” of the STH railway system? The Company selected the contractor for feasibility study

The Solidarity Transport Hub company selected the most advantageous tender for the performance of preparatory works for the next investment task – the STH railway node. Its construction will ensure the integration of the Solidarity Airport with the national railway connection network – both for high-speed rail and for regional and commuter trains.

Yesterday's decision of the Company is the second final decision made in the tendering procedure for the execution of the so-called STEŚ for a fragment of the STH railway network. The results of the tendering procedure for the Warsaw – Łódź section were published on Thursday.

The STH node is the central component of the whole railway system, which is the largest part of the STH Programme. It will be a facility that will integrate all modes of transport – rail, air and road – in one place. For this reason, it will be one of the most complex infrastructure investments in recent years.

Difficult task facing the contractor. Even renowned engineering companies rarely deal with such a complex project. The STH node will be fully integrated with the airport. It will be able to handle over half of long-distance railway connections in Poland, as well as regional and commuter railway. This will enable passengers to reach the Solidarity Airport from all sides of the world. The layout of the node will also allow passengers boarding or transferring from one mode to another at the STH to travel in each of these directions. The agreement shall be signed immediately after the tendering formalities have been completed.


The STH node will be located at the interface of the most important railway lines in Poland, including:

  • line No. 85 from Warsaw towards Łódź, Sieradz, Wrocław and Poznań (as part of the so-called spoke No. 9),
  • line No. 5 towards Płock, Włocławek, Tricity, Bydgoszcz and Toruń (as part of spoke No. 1),
  • line No. 4 (Central Trunk Line) towards Katowice and Kraków (as part of spoke No. 7),
  • line No. 88 towards Warka, Radom, Sandomierz and Rzeszów (as part of spoke No. 6),
  • line No. 1 towards Częstochowa, Opole and Kłodzko (as part of spoke No. 8),
  • line No. 3 towards Kutno and Konin (as part of spoke No. 10).

The STH node construction will be for the benefit of not only long-distance connections’ passengers. Users of regional and agglomeration routes will also benefit from this. There will be convenient connections between, among others, Grodzisk Mazowiecki, Żyrardów, Sochaczew and Błonie with Warsaw and the planned airport, and regional express trains will ensure quick connections with the towns of the western Masovia (e.g. Płock) and the Łódzkie Voivodeship.

The subject of the contract is the execution of the so-called STEŚ, i.e. the feasibility study for the planned STH railway node covering the sections of railway lines on long-distance routes:

  • the section of railway line No. 85 between the Tłuste area and the Wiskitki area (the remaining part of the Warsaw – Łódź route is covered by a separate contract which was awarded on 13 May 2021),
  • section of railway line No. 5 between the Korytów station at the interface with the Central Trunk Line and the point of intersection with line No. 3 (Warsaw – Poznań) in the Sochaczew, Teresin and Niepokalanów area, and
  • links between lines No. 5 and 85 in a configuration depending on the option.

And on regional routes:

  • sections of railway lines ensuring connection between line No. 3 (Warsaw – Poznań) at the interface between Błonie and Sochaczew and line No. 1 (Warsaw – Łódź) or possibly extension of line No. 447 at the interface between Żyrardów and Grodzisk Mazowiecki, and
  • links between lines No. 1, 3 and 447 in a configuration depending on the option.

The tender of the Egis Poland, Egis Rail (France) and Jaf-Geotechnika Consortium was considered the most advantageous one. The successful consortium submitted a tender amounting to netPLN 19.9 million. Other tenders were submitted by the Multiconsult Polska, Arcadis, Transprojekt Gdański and IDOM Inżynieria, Architektura i Doradztwo consortium (net PLN 32.97 million) and Voessing Polska (net PLN 35.8 million).

The selection was determined by the price (50%) and staff experience (the remaining 50%).

In accordance with the public procurement law, the last formalities must be completed before the procedure is concluded. Appeals which may potentially extend the procedure may be lodged therein. It will be concluded by signing an agreement with the contractor which will commence the performance of the commissioned services.

The contractor selected in the tendering procedure will have approx. 10 months, for the preparation of the STEŚ and for the execution of the scope of geotechnical documentation and maps for design purposes, and settlement of the entire agreement – almost2 years from the date of signing the agreement with the Contractor.

As part of the STEŚ, the Contractor shall deliver to the STH company, among others, traffic forecasts as well as analyses – e.g. operation and maintenance, technical, environmental and multi-criteria – and shall prepare the soil survey report and maps for design purposes. The purpose of the STEŚ is to prepare specialised documentation for the railway line for design purposes, including indication of its recommended course.

On the lines comprising the STH node, trains will be able to speed up to a maximum of 250 km/h. For the purposes of the STH high-speed system, the designers assume the use of 25 kV AC power supply. For the regional connections’ system, 3kV DC or 25 kV AC power supply will be used.

According to the programme, the first construction works are to start in 2023. STH assumes that the node will be handed over for operation by the end of 2027 to ensure fast railway connections with the launch of the Solidarity Airport.

The next stage of preparatory works – after completion of the STEŚ – will be preparation of the design documentation, i.e., among others, the conceptual design, materials for the environmental decision and the building permit design. The STH company is at the final stage of preliminary market consultations prior to the announcement of the tendering procedure for the framework agreement for preparation of the design documentation for 30 investment tasks.

The STH Railway Programme assumes that almost 1,800 km of new lines are to be constructed by the end of 2034. These investments consist of a total of 12 railway routes, including 10 “spokes” leading from various regions of Poland to Warsaw and the STH.
