Project’s key data
 Section Kolín-Břeclav-state border Austria/Slovakia - part
of the Pan-European corridor IV, Czech Republic, EU
 Tender floated 06/2011, contract awarded 06/2012,
commissioning scheduled for the end of 2014
 Length 277 km double track, 3250 balises to be placed
 8 RBCs to be installed, all centralized at one place
 Mixed traffic of ETCS fitted and non-fitted trains
 AZD furnished its own ERTMS measuring car
 Unique track mapping methodology developed
 Special national functions above ERTMS spec.

Technical highlights
 Fully own AZD ETCS L2 solution
 ETCS L2 according to specs. 2.3.0d (Baseline 2)
 Level 2 “dynamic” cross border handover Czech R. to
Austria without any RBC-RBC communication
 Each RBC shall serve more than 60 ETCS trains, key
management system and key distribution systems features
embedded
 There have been:
 31 interlocking systems of three types to be interfaced
 Four types of open line signaling systems to be interfaced
 Three types of level crossing systems to be interfaced

Track mapping method
 Precise track mapping is for ETCS L2 an essential
design preparatory activity
 A brand new track mapping method has been
developed – recording video + odometric data +
GPS position
 Device mounted on a vehicle
 Mapping activities:
● Manual colour marking objects of interests in the field
● Loco measuring runs (2 x each section)
● Offline data editing, processing and ETCS preparation design
data
 All the track mapping activities already done

Mixed traffic
 Mixed traffic in this project means the system shall
always manage both ERTMS equipped and non
equipped trains, while any train fitted with ERTMS in
failure is handled as a non-fitted one
 That brings:
● Non-fitted trains run as per existing conventional rules
and signalling systems – not limited by ETCS rules
● RBC may not evaluate clearing a track section just
based on the ETCS fitted train reports
● RBC will always estimate there is a non-fitted train
ahead any ERTMS fitted one
● RBC needs enhanced algorithms for generating static
speed profiles
RBC software for mixed traffic is much more
extensive and complex - in terms of
development as well as safety assessment

RBCOBB
Czech ETCS L2 Project connects to ETCS L2 „Nord Bahn“ line ÖBB, Austria
Cross border section (6 km) single block, no intersection signals
Only one train on each track in cross-border at one moment
No communication RBC AŽD - RBC ÖBB foreseen
GSM-R networks do overlap each other
Handover process based on dynamical RBC zone entering/leaving procedures
Train communication to new/departed RBCs initiated by a dedicated balise
There is no need for any cross border RBC - RBC interconnection, while
fluent train movement is achieved (2 GSM-R onboard units assumed)
First time in Europe cross border handover of this type

PROJECT CURRENT STATUS
 First section (1 RBC) already in service
 Testing of ETCS trackside equipment and GSM-R
going on using own AZD ERTMS measuring car
 Safety and interoperability certification on the way
 Customization development of the AZD RBCs
following functional test results
 Adaptations, modifications and interfacing of the
conventional signalling systems
 Commissioning scheduled for end of 2014
