The section of Line E30 between Legnica and Bielawa Dolna has been equipped with Bombardier's Interflo 450 ERTMS Level 2 wayside signalling system under a Zlotys 54m ($US 17.7m) contract awarded by PKP PLK in 2010.

Initial tests are focussing on interaction between trackside and onboard equipment and will simulate a number of degraded operating scenarios. Tests are being carried out using a PKP Intercity EP09 electric locomotive equipped with ETCS.

The ERTMS Level 2 pilot project is part of the modernisation of the Legnica – Bielawa Dolna line, which is being funded by the European Union Cohesion Fund through the Operational Programme Infrastructure and Environment.
