The project required a type-conformity certificate from an accredited body and a type-approval certificate from the Polish Railway Transport Office for the new dispatcher terminals. It also involved surveying, reconfiguring and integrating PKP PLK’s existing SDH-based transmission network with newly built MPLS infrastructure. All activities had to be coordinated simultaneously at 115 railway facilities operated by nine Regional Track Units throughout the country.

An interdisciplinary project team defined the optimal device configurations and ensured full compliance with legal and normative requirements. A dedicated laboratory was established at company headquarters to test the interoperability of SDH and MPLS systems and to conduct certification trials in cooperation with the Military Institute of Armament Technology. Installation and integration tasks were scheduled in stages, maintaining uninterrupted service on the PKP PLK transmission network during implementation.
