The Polish State Railways is the dominant railway operator in Poland. The company was founded when the former Polish State Railways state-owned enterprise was divided into several units based on the need for separation between infrastructure management and transport operations. Polish State Railways is the dominant company in PKP Group collective that resulted from the split, and maintains in 100% share control, being fully responsible for the assets of all of the other PKP Group component companies. The group's organisations are dependent upon Polish State Railways, but proposals for privatisation have been made.
