PKP Polskie Linie Kolejowe did not inherit all infrastructure-related aspects of the former Polish State Railways, those that directly dealt with construction works were intentionally kept apart, and were partially privatised as separate entities.

[5] Instead, the new infrastructure management organisation came to agreements with those contractors, as well other parties, on a competitive and fair basis in accordance with binding Public Procurement Law; the treatment of all bidder and the overall bidding procedure were monitored as a precaution against irregularities by the Polish government.

These works, costed at in excess of €36 billion and primarily funded by the European Union, sought to complete a high-speed railway network, raising the maximum speeds on several different lines to 200km/h, as well as to construct or modernise rail links to various major airports and international transport corridors.

[10] One of the benefits of the infrastructure modernisation and provision of higher line speeds was enabling PKP Intercity to launch operations of its New Pendolino high-speed trains between the Polish cities of Warsaw, Gdańsk, Wrocław, Krakow, and Katowice.

[13] Conventional services, both passenger and freight, have also been permitted to run faster when feasible to do so; another areas of improvement is safety, which has been helped by the implementation of continuous digital communication and a reduction in grade crossings amongst other measures.
