On the newly made peripheral line, the dynamic passenger information system was installed by Kolejowe Zakłady Łączności. As part of the task of modernizing the perimeter line, KZŁ Bydgoszcz provided, installed, and programmed 28 two-sided platform boards, 5 standing information boards and 10 external infokiosks. In addition, KZŁ Bydgoszcz provided a time network system armed with 12 station clocks.

In cooperation with PKP PLK SA the installed SDIP elements were connected to the Central Dynamic Passenger Information System of PKP PLK. The task was also extended with the installation of systems on the 8 platform of the  West Warszawa station, where the installed devices were integrated with the existing passenger information system.

Soon, the installed system will be expanded with end-of-train detection devices. The implementation of the SDIP system on the perimeter line was one of the more complex tasks related to the installation of passenger information boards on railway lines, but the whole task was carried out efficiently and on time, and the effects of modernization can already be enjoyed.

Kolejowe Zakłady Łączności currently also implements another major project related to equipping the SDIP with several smaller stations in Poland. Here, in cooperation with PKP Telkol, solutions will be put into operation at several dozen locations soon.
