Sagemcom GSM-R regional workshop 12-14 April 2011 Villány, HUNGARY Mr. Damir Zaborski, dipl.ing - damirz@srbrail.rs Aleksandar Radonjić, dipl.ing - aleksandar.radonjic@srbrail.rs

Overview of existing Radio Communication System Overview of law and internal regulative Plain to implementing GSM-R pilot project

Overview of Railway network Total length of track is 4.084,281 km Total length of track lines is 3.808 km 3.533 km of single track lines (92%) 275 km of double track lines (8%) Electrified with 25kV@50Hz is 1.196 km (29% of total length) 925,025 km of single track lines (77%) 271,026 km of double track lines (23%) On Corridor X is 769 km On Belgrade – Montenegro is 287 km

There are 8 track lines equipped with Analog Radio System. Analog Radio, based on UIC 751-3 (Technical regulations for international analogue ground-train radio systems) also known as Radio Dispatch System Use for train to dispatcher communication all over the track, projecting with coverage probability of 95% in time and 95% of locations There are 8 track lines equipped with Analog Radio System. 7 of them is on corridor X and one is on track Belgrade – Montenegro

Coverage of analog radio on Serbian Railways BTS- Base Transmitter Station

Coverage of analog radio on Belgrade and Niš railway node

Base station with 20m height mast at open track

Base station with 20m height mast near railway station

Base station with 12m height mast at open track

Base station mounted in tunnel using HELIX antennas

We use 3 types of differnet CAB Radios TFZ 70 by Telefunken, 75 radios, from ‘70 TFZ 90 by AEG, 65 radios, from ‘90 MESA23 by Funkwerk, 55 radios, from 2010

TOTALLY = 495 radios and 12 repeaters There are many simplex/semiduplex radio networks grouped in familiar sub-networks Train listing, 55 portable/fixed radios Shunting radio, 125 portable/fixed radios Train maintenance, 35 portable/fixed radios Traffic operations, 45 portable/fixed radios Infrastructure maintenance, 165 portable/fixed radios Other, 70 portable/fixed radios TOTALLY = 495 radios and 12 repeaters

Memorandum of uderstanding Project declaration proposal for the installation of ERTMS/ETCS system in CORRIDOR X Composed at Zagreb 2003 Signatories: SŽ (Slovenia)-HŽ(Croatia)-MAV(Hungary)-ŽS(Serbia)-NRIC(Bilgaria) and UIC

Highlights of the project declaration Implementation of ETCS on the following lines: Ljubljana - Zagreb – Belgrade Budapest – Belgrade Niš – Sofia Belgrade – Adriatic Sea The objective is to acquire a fully operational new ERTMS system for regular use on each of these lines

Relevant map for Corridor X and surroundings on which the lines pending ERTMS/ETCS incorporation or already equipped with it are indicated

Serbian railways telecommunication strategy General Project of integrated telecommunication system at Serbian Railways, January 2008 This is the official documents approved by the Board of Directors of Serbian Railways This document describes main guidance for future evolution of railway telecommunication system, also including and GSM-R

National radio-spectrum regulative Republic agency for electronic communications (RATEL) is regulation body in Serbia In accordance with allocation plan of radio frequency bands (June 2005), radio spectrum at 876-880MHz and 921-925MHz is reserved for railway communications These days the army is still using this part of the spectrum, but their plan was to leave the frequency for GSM-R

Plain to implementing GSM-R pilot project Building own optical infrastructure (2011/2012) Building own SDH transport network (2012/2013) Creating project documentation for GSM-R pilot project (2012) Creating project documentation for implementation and preparing tender documentation (2013) Equipment acquisition and starting to building GSM-R pilot network (2014)

PILOT PROJECT FEATURES Line Belgrade – Šid – State Border (HŽ) Radio coverage according to ETCS level 2/3 Using site infrastructure (buildings and masts) of analog radio, as much as possible Using existing railway power distribution cable for BTS powering Using own SDH transport network for BTS/BSC/MSC connectivity Using dual mode cab radios (analog + GSM-R)
