Nokia says this is the company’s largest GSM-R contract and it will provide installation, commissioning, third-party integration, first-line care and maintenance across the 13,800km GSM-R network plus more than 11,000km of optical fibre-based backhaul network infrastructure. This will include IP Multicprotocol Label Switching (IP/MPLS) and dense wavelength division multiplexing (DWDM) optical network equipment.

The project is majority funded by the European Union and complemented by Polish government funds. Once completed, the new network will enable PKP PLK to fulfil EU requirements for ERTMS.

Herkules, Pozbud and Wasko will be responsible for civil works, including construction work for laying fibre.
