Railway component

Railway system

Solidarity Transport Hub Poland (STH) is an emerging infrastructure megaproject including two major components: a new internationalairport, 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 adopted by the Government of Poland. The airport, along with the first portion of the railway system, are scheduled to be opened at the end of 2027.

The STH railway system will be based on approx. 1600 km of new high speed rail (HSR) lines and 2400 km upgraded existing railway lines. Completion of the STH railway program is one of the biggest ongoing engineering projects in Central Europe, involving 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 railway system planning concept includes the following preliminary assumptions for its high speed sections:

  • Design speed up to 350 km/h, operational speed ≥250 km/h
  • 25kV 50Hz AC electrification on the core HSR network
  • Full interoperability and compliance with all modern EU rail traffic control standards
  • Frequent high-speed intercityservice, with possible rapid regional trains and nighttime freightoperations permitted on selected sections
  • 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 Airport from the 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 Eastern Europe
  • Bringing convenient rail services to the currently isolated remote regions of Poland
