Slovenske železnice - Infrastruktura d.o.o. – Network Statement of the Republic of Slovenia 2014 – 9.12.2012 – 03.3.3.3. Radio Dispatch ConnectionsRadio dispatch connections (RDZ) have been developed especially for railroads, and theyallow uninterrupted telecommunication connection between the train (locomotive) and thedispatcher centre on certain sections of the train route. They present rational and necessaryinstruments for the railroad traffic management.Due to possibility of direct emergency call in both directions the radio dispatch connection isa supplement to the existing railway signalling and traffic control systems and increases thegeneral safety of the traffic. RDZ consists of: RDZ base stations, Radio dispatch centre, RDZ locomotive station.The RDZ system operates within the radio frequency ranges from 457,450 MHz to 458,300MHz and from 467,450 MHz to 468,300 MHz.The connection between the locomotive and the train route dispatcher is established by aselective call. Commands or messages are transferred in a coded digital or phonic form.Messages and orders may be sent by activating appropriate pre-programmed keys. Thereception of coded messages is optically and acoustically indicated on light fields, which aredesignated by anticipated symbols.The number of the train, which can be a six digit number, is used as a reference number.Since the selective call makes the line busy (blocked for the rest of the trains) for as long asthe information is being transferred. The speed of 600 Bauds is used for the transfer ofcoded messages. This makes the line busy for as little time as possible and is approximately100 milliseconds. If the message is not received by the receiver for whatever reason, theprocess is repeated automatically.In an emergency situation, the communication desk in the radio dispatcher station allows forsimultaneous calls of all the locomotives in a certain RD train route section. Likewise, it ispossible to make an emergency call from the locomotive to the radio dispatch stationdespite the busy line. The frequency diversity switches the locomotive receiver to thefrequency which has the strongest field at a given moment. After changing the radiodispatch section, the frequency has to be set up manually.On the train side, the radio dispatch system provides the connection with the public addresssystem, while on the radio dispatch station side it provides the connection with the railwaytelephone network and other communication systems.Each radio dispatch section represents a closed technical and technological unit whichcannot be interrupted by other sections. Junctions of RDZ systems are covered betweeneach other. The designations of junctions on the railroad consist of the mark RDZ K and thenumber of the radio channel.3.4. Traffic Restrictions3.4.1. Specialized InfrastructureFor timetable period 2013/2014 the following lines are defined as specialised infrastructure: (Čakovec) – d.m. - Lendava, which do not have a direct connection with the homePAGE 32
Slovenske železnice - Infrastruktura d.o.o. – Network Statement of the Republic of Slovenia 2014 – 9.12.2012 – 0country, Grosuplje – Kočevje, intended only for limited freight traffic (the passenger carriage ispossible exclusively after signing a special agreement), Ljutomer – Gornja Radgona, intended only for freight traffic (the passenger carriageis possible exclusively after signing a special agreement), Branching Kreplje - Repentabor - d.m. - (Villa Opicina), intended only for limitedtraffic after signing a special agreement.3.4.2. Environmental RestrictionsThe RUs providing transport operations on the territory of the Republic of Slovenia shall: observe all rules necessary to prevent and reduce the burden on the environment, take all necessary measures which prevent and reduce the environmental pollution,so the emissions to the environment do not exceed the prescribed limits, in case of an environmental accident, immediately inform the IM, which isresponsible to inform the competent authority and take all urgent measures toreduce the harmful consequences for the environment.The environmental restrictions in regard to the rail transport, which have to be fulfilledwhile providing rail transport services, are defined in: The Environmental Protection Act - Officially consolidated text – ZVO-1-UPB1 (OfficialJournal of RS, No 39/2006), Meteorological Activities Act – ZmetD (Official Journal of RS, No 66/2006), Spatial Planning Act - ZPNačrt (Official Journal of RS, No 33/2007), Financing of Municipalities Act - ZFO-1A, (Official Journal of RS, No 57/2008), Act Amending the Environmental Protection Act – ZVO-1B (Official Journal of RS, No70/2008, 43/2011), Act Amending the Environmental Protection Act – ZVO-1C (Official Journal of RS, No108/2009), Executive regulations of The Environmental Protection Act (ZVO-1), published at thewebsite of the Ministry of the Environment and Spatial Planning.3.4.3. Dangerous GoodsThe transport of dangerous goods is carried out on all PRI lines, in accordance with therequirements of the state authorities, Rules on the transport of dangerous goods, provisionsof the ZVZelP and other related regulations.3.4.4. Tunnel RestrictionsThe tunnel restrictions, with regard to the spatial dimensions of particular wagons in a trainin a combined transport are considered with the codification of lines. For the otherconsignments the spatial restrictions are valid, which defined by the clearance and loadinggauge and stated in Annex 3/4 of this document.In Bohinj tunnel on rail line No. 70 Jesenice - Sežana traffic limitations are foreseen in case offloods or increased level of water. Those limitations are described in the Station rules ofoperations of Bohinjska Bistrica railway station. There are no other special limitations in theother tunnels of the PRI.PAGE 33
