The financial resources allocated for upgrading the railway infrastructure in Poland over the last decade have brought measurable benefits in the length of railway lines with increased speed. In addition to the upgrade of railway tracks with supporting infrastructure, electrical power equipment and networks or control-command and signalling equipment, further railway lines are equipped with ERTMS/ETCS track-side equipment. All upgraded or retrofitted railway lines are subject to a certification process in accordance with European or national law. Among these lines with the A-Class system and the EC certificate of verification, there are cases where action should be taken to improve the performance of the railway infrastructure. Analysing various investment processes, the article looks at the impact of the tenders for ERTMS/ETCS track-side equipment, which legitimize the validity of the issued EC verification certificates, and whether they have authorisation for placing in service issued by the President of Urząd Transportu Kolejowego (Office for Railway Transport).
