AD Consorcium NOKIA NSM – THALES
During the period from 12 November 2013 to 15 January 2016, ATDI as a subcontractor of THALES took part in the project “Design, construction and implementation of ERTMS / GSM-R radio subsystem, design and construction of fiber-optic cables and construction of teletransmission systems under the project. OPI & E 7.1-25 “Construction of the infrastructure of the GSM-R system according to NPW ERTMS on the E20 / CE20 railway line corridor F on the section Kunowice – Terespol” for the LOT Lowicz Glowny – Terespol.
The project included: (600,00 km railway lines).
The contract includes the design, assembly, construction and commissioning of the GSM-R BSS subsystem for the deployment section together with the necessary construction of new optocommunication cables, telecommunication transmission systems, hardware and software upgrades of the NSS subsystem, the accompanying and teletransmission infrastructure of the Ordering Party. The order also includes delivery of GSM-R mobile terminals, SIM cards and stationary terminals and dispatchers (FDS) with the necessary accessories.
ATDI was responsible for the design documentation for the part related to the construction of new optocoupler cables and the development of the teletransmission system.
The project concerned the implementation of the task on the following sections of railway lines:
– 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)
The following tasks were performed:
– construction of optical line telecommunication lines,
– development of STM-16 and STM-4 SDH telemetry transmitters for the transport layer,
– development of access layer devices for realization of the dispatching network,
– retrofitting of the 1350 OMS management system in the OC1 Warsaw central facility in the necessary licenses.
The signal transmission between BTSs and GSM-R BSCs is implemented in the SDH rings formed on the respective E 20 and C-E 20 lines, which act 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.
1.1. 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.
Fiber allocation in fiber optic cables is as follows:
– fiber 1-2 main transmission ring SDH,
– fiber 3-4 GSM-R transmission between BTS and SDH,
– fiber 5-6 signaling to FDS terminals,
– fiber 7-12 GSM-R reserve,
– fiber 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 fiber), with 48 monomodal fibers (48J) according to ITU-T G-652.
Fiber optic cables in the aforementioned cables used for SDH transmission are single mode fibers for transmitting in the II and III transmission windows, wavelengths of 1300nm and 1550nm respectively.

Study I – GSM-R network coverage analysis report – Network dimensioning: RailCorp wishes to simulate the migration of its 400MHz analogue network to a 1800 MHz GSM-R digital network. In order to do so, the number of required base station must be evaluated. ATDI bases its evaluation the planning tool ICS Telecom, that is already owned by Railcorp.
Study II – Tuning Phase: measurement phase by making fake emission along the track and getting samples – 1 month of runs and measurement made. Data introduced after treatment in ICS telecom to get a tuned project.
Study III – DTRS Preliminary design – Verification of work made by UGL and Huawei based on information provided by RailCorp – Used better carto. See proposal RFP No. 106332LB
