Solidarity Transport Hub (STH) is an emerging infrastructure mega project, which includes two major components: a new international airport constructed from scratch in the suburbs of Warsaw and a new nationwide railway system consisting of 10 major corridors radiating from the STH Airport towards all regions of Poland. The STH is currently in its initial planning phase, with several conceptual decisions already being adopted by the Government of Poland. The airport and the first section of the railway system, are scheduled to be opened at the end of 2027.
The STH railway system will be based on approximately 1800 km of new high-speed-rail (HSR) lines and 2400 km modernized railway lines. Completion of the STH railway program is one of the biggest ongoing engineering projects in Central Europe. It involves the adoption of finest HSR design standards, technical parameters and planning procedures, many of which will be implemented for the first time in the entire region. The STH’s railway planning concept includes the following preliminary assumptions for its high-speed sections:
- Designed speed of up to 350 km/h
- Operational speed of ≥250 km/h
- 25kV 50Hz AC electrification of the core HSR network
- Full interoperability and compliance with all modern EU rail traffic control standards
- Full connectivity with the existing railway system.
Upon completion, the STH railway system will comprehensively address numerous mobility needs, including in particular:
- Providing fast, frequent, and seamless access to the STH and the Solidarity Airport from nearby cities of Warsaw and Lodz
- Forming Poland’s core high-speed-rail network, linking nation’s largest urban areas and serving major international routes running across Central and Eastern Europe
- Bringing convenient rail services to the currently isolated remote regions of Poland.
