Poland-based PKP Group’s rail track maintenance firm PKP Polskie Linie Kolejowe (PLK) has chosen Nokia Solutions and Networks’ (NSN) GSM-Railway (GSM-R) communications solution to modernise mobile network on a 440km stretch of the country’s E-20 railway corridor.

Based on synchronous digital hierarchy (SDH) and ethernet technology, the GSM-R communications solution will provide a secure digital infrastructure for PLK.

The mobile network will cover the railway section between the central city of Lowicz and Terespol, while the deployment is expected to be completed during the fourth quarter of 2015.

"This will ensure greater safety for trains and passengers while increasing travel speeds."

NSN will work in association with technology firm Thales, which will build turnkey transmission including fibre-optic cables network.

Under the agreement, NSN will deploy its base stations and base station controller, and also provide a network design, project management, network implementation and maintenance services for seamless integration.

The deal also includes NSN’s NetAct network management system to ensure network efficiency and stability.

NSN railway solutions head Dirk Lewandowski said: "This contract marks an important extension of our railways communications projects in Poland after being selected to provide our mobile infrastructure for the strategic Warsaw-Gdynia railway line.

"By deploying our leading GSM-R technology, data transmission will eliminate the need for external traffic lights along the tracks, using proven automatic signaling technology to the train instead.

"This will ensure greater safety for trains and passengers while increasing travel speeds and the capacity of railway operations."

NSN has deployed around 30 GSM-R networks in 21 countries to date.
