Press Release
Warsaw, Poland – February 12, 2013  
Nokia Siemens Networks to supply mobile network for Polish Railways
GSM-R network will enhance security and speed on train line linking Warsaw and 
Nokia Siemens Networks will provide its GSM-Railway* (GSM-R) 
infrastructure for a major rail line in Poland. The nation’s rail network 
management, PKP Polskie Linie Kolejowe, is modernizing this highly complex 
35-station line linking Poland’s capital, Warsaw, with the northern Baltic port 
of Gdynia. 
The deployment of the GSM-R network along the 350-kilometer section of Poland’s 
E65 line will provide a communications backbone for the European Rail Traffic 
Management System (ERTMS) solution. The project will be carried out by a 
consortium of Nokia Siemens Networks, Thales Polska Sp. z o.o. and Bombardier 
Transportation, introducing ERTMS standards to this busy passenger and freight 
While Thales Polska and Bombardier Transportation are in charge of designing, 
developing and implementing the Level 2 European Train Control System** (ETCS) 
signaling part, Nokia Siemens Networks is responsible for the entire GSM-R 
project including network expansion and rollout.  
“Nokia Siemens Networks’ GSM-R communications will help PKP Polskie Linie 
Kolejowe ensure greater safety for passengers travelling on the Warsaw-Gdynia 
high-speed route,” said Andrzej Wolski, project director at PKP Polskie Linie 
Kolejowe. “The modernization will also allow us to shorten travel time by 
increasing the speed of our modern trains, which will be able to run at up to 
200 km/h in selected sections.” 
Nokia Siemens Networks will provide its market-leading GSM-R radio network 
equipment, including base stations, base station controller, the transmission 
backbone, as well as the dispatchers and handheld terminals. In addition, the 
company will deploy its maintenance system for Railways (NetAct) 
ms/netact) and integrate ETCS Level 2 signaling for the GSM-R turn-key project. 
The solution will be put into commercial operation in the second quarter of 
“This project underlines our global leadership in the GSM-R market where we 
have more than a 50% share in the deployed GSM-R tracks. It further strengthens 
our position in Poland as a leading mobile infrastructure provider, also 
outside traditional telecommunication sector,” said Piotr Kaczmarek, Poland 
country director at Nokia Siemens Networks. 
Nokia Siemens Networks’ GSM-R system meets the enhanced safety, 
interoperability and quality expectations of railway operators while reducing 
operational costs and providing additional differentiation potential in the 
transportation market.
