PKP Polish Railway Lines S.A
Supply of GSM-R radio planning for railway lines covered by the National Implementation Plan ERTMS in Poland” – 7 283,188 km of railway lines (1 128 BTS).
AECOM for Croatia railway line
Supply of propagation planning services for the radio network on the line Goljak – Skradnik and Croatia railway line – 40 km, including three tunnels.

NOKIA NSM – THALES consortium
ATDI supported THALES design, construct and implement a ERTMS / GSM-R radio subsystem, including fibre-optic cables and the construction of tele-transmission systems. The project covered 600,000 km of railway line and included the design, assembly, construction and commissioning of the GSM-R BSS sub-system for deployment. GSM-R mobile terminals, SIM cards and stationary terminals and dispatchers (FDS) were also delivered, with the necessary accessories.
ATDI provided the design documentation for the construction of new opto-coupler cables and the development of the tele-transmission system.
The project encompassed the following sections of the rail network:
– Line No. 3 section Warsaw West – Łowicz Główny (E-20)
– Line No. 2 section Warszawa East – Terespol (E-20)
– Line no.11 Łowicz Główny section – Skierniewice (CE-20)
– Line No. 12 section Skierniewice – Lukow (CE-20)
– Construction of optical-telecommunication lines
– Development of STM-16 and STM-4 SDH telemetry transmitters for the transport layer
– Development of access layer to enable the dispatch network
– Refitting of the 1350 OMS management system in the OC1 Warsaw central facility across appropriate licenses.
Optical fibre-optics cable lines
The signal transmission between BTS and GSM-R BSC was implemented on the SDH rings formed on the respective E 20 and C-E 20 lines, which acts as a synchronous backbone network with automatic, alternating transmission.
SDH rings were made in the following relationships:
– line E 20 (line no. 3): OR Lowicz – adjusting West Warszawa
– line E-20 (line No. 2) can be adjusted to the east of Warsaw – OR Oleksin – OR Krynka – OR Puchacze – OR Terespol, two basic fiber optic cables and loop closure
– line C-E 20 (lines 11 and 12): OR Łowicz – OR Piotrkowice – OR Pilawa – OR Łuków, in the basic fiber optic cable with closed loop transmission by the SDH system from the E 20 line.
Designated cable lines built under this investment task
Along the line No. 2 on the section ND Biala Podlaska – ND Terespol (TRB) and along the line No. 3 on the section ND Warszawa West – Łowicz Główny (building at 7 Dworcowa Street) was built fiber optic cables:
– basic cable – Z-XOTKtsd 48J (along track 1),
– closing cable – Z-XOTKtsd 48J (along track 2).
The Z-XOTKtsd 48J fiber optic cable has been built along the line NO. 11 on the section NW Skierniewice SKB – Łowicz Główny (building at 7 Dworcowa Street) and along the line NO. 12 on the section Skierniewice SKB – LCS Łuków.
Fibre allocation in fibre optic cables as follows:
– fibre 1-2 main transmission ring SDH,
– fibre 3-4 GSM-R transmission between BTS and SDH,
– fibre 5-6 signaling to FDS terminals,
– fibre 7-12 GSM-R reserve,
– fibre 13-48 reserve.
The cables described above are external (Z), polyethylene (X), optoelectronic (OTK), dry (ts), dielectric (d) tubular, made of a multi-piece structure with loose twisted tubes around the dielectric central Endurance element (FRP rod – impregnated glass or aramid fibre), with 48 monomodal fibres (48J) according to ITU-T G-652.
Fibre optic cables in the aforementioned cables used for SDH transmission are single mode fibres for transmitting in the II and III transmission windows, wavelengths of 1300nm and 1550nm respectively.
