4 What ETCS is The European Train Control System ETCS supervises train movement in regards to speed and distance travelled, based on information provided by an underlying signalling system ETCS consists of onboard and trackside subsystems performing standardised functions and are communicating via Eurobalise, Euroloop and GSM-R using standardised protocols ETCS provides full cab signalling and can be used either as an overlay onto classical signalling systems with lineside signals or without them The term ERTMS is used when referring to ETCS and GSM-R as one system ETCS has been developed to replace all existing mainline train control systems in Europe page 4 Wildenrath, 17 February 2012

5 What ETCS is ETCS is fairly complex, as it has to deliver at least the functionality and performance of all systems it shall replace Some requirements have been pushed even higher, e.g. the operating speed to 500 km/h ETCS has to comply with the newest safety standards, and has been designed to achieve SIL 4 (Safety Integrity Level), the highest safety level As a result of all these requirements ETCS is significantly more expensive than most existing legacy systems that only provide basic functionality (e.g. TPWS, Crocodile, TBL) page 5 Wildenrath, 17 February 2012

6 What ETCS is not ETCS does not cover the aspects of interlocking and traffic management ETCS is also lacking some function found in more advanced systems, especially CBTC systems, such as automatic train operation or remote diagnostics. ETCS will however evolve over the years, and some of these functions are already planned to be included in future baselines. page 6 Wildenrath, 17 February 2012

7 Goals of ETCS Goals of users Reduction of the number of required systems for cross border traffic Simplification of cross border operation (e.g. no change of locomotive at border, operating rules) Increase of line capacity Increase of safety Political goals of European Union Improving competitiveness of rail transport Opening of national networks to outside operators (free access) Competition between suppliers page 7 Wildenrath, 17 February 2012

9 Introducing ETCS Today each country in Europe has between one and three train control systems in use With the introduction of ETCS these systems shall be eliminated to allow seamless operation of trains across Europe A solution has therefore to be found how to introduce ETCS across Europe and how to eliminate existing national systems page 9 Wildenrath, 17 February 2012

10 Introducing ERTMS Today there are at least 18 different train control system in use in Europe Ebicab 700 Ebicab 900 AWS, TPWS, TBL ZUB 123 ATB-EG, ATB-NG, TBL Indusi (IATC), LZB, GNT TBL, Crocodile SHP TVM, KVB, Crocodile LVZ, LSD ASFA, LZB, Ebicab 900 EVM Ebicab 700 Ebicab 700 Signum, ZUB 121 / 262 Indusi, also in RO, HR, YU, SI BACC, RSDD, SCMT page 10 Wildenrath, 17 February 2012 Indusi, LZB

11 Introducing ETCS Goal of ERTMS/ETCS: Only one train control system all over Europe ERTMS/ETCS page 11 Wildenrath, 17 February 2012

12 Introducing ETCS Example of antenna arrangement on a vehicle for cross border traffic Switzerland France Germany prior to introducing ETCS KVB Balise antenna Integra receiver Integra permanent magnet ZUB 121 LZB transmission aerial Crocodile brush Indusi PZB 90 LZB receiver aerial page 12 Wildenrath, 17 February 2012

13 Introducing ETCS Typical antenna arrangement on a vehicle for cross border traffic (what it should look like): ETCS balise / loop reader page 13 Wildenrath, 17 February 2012

14 Introducing ETCS Key question is: ERTMS/ETCS how to get there in a reasonable time and at affordable cost page 14 Wildenrath, 17 February 2012

15 Introducing ETCS To simplify migration to ETCS a concept has been developed as part of the ETCS standard to allow ETCS equipped trains to run on lines equipped with legacy systems, using Specific Transmission Modules (STMs) The STM concept is an onboard concept, as trains are made to be compatible with tracks where either national systems or ETCS is used page 15 Wildenrath, 17 February 2012

16 Introducing ETCS with STMs Introducing ETCS with STM s (Note: 3 countries have full ETCS rollout strategies): ETCS + Ebicab 700 ETCS + Ebicab 900 ETCS + AWS, TPWS, TBL ETCS only ETCS + ATB-EG, ATB-NG, TBL ETCS + Indusi (IATC), LZB, GNT ETCS only ETCS + SHP ETCS + TVM, KVB, Crocodile ETCS + LVZ, LSD ETCS + ASFA, LZB, Ebicab 900 ETCS + EVM ETCS + Ebicab 700 ETCS + Ebicab 700 ETCS only ETCS + Indusi, also in RO, HR, YU, SI ETCS + BACC, RSDD, SCMT page 16 Wildenrath, 17 February 2012 ETCS + Indusi, LZB

18 Introducing ETCS with STMs Issues with STMs Cost Complexity Installation space Energy consumption Availability Maintenance Operating rules Note: cost figures from SBB study page 18 Wildenrath, 17 February 2012

19 Introducing ETCS with STMs Goals of users Reduction of the number of required systems for cross border traffic Simplification of cross border operation (e.g. no change of locomotive at border, operating rules) Increase of line capacity Increase of safety Political goals of European Union Improving competitiveness of rail transport Opening of national networks to outside operators (free access) Competition between suppliers page 19 Wildenrath, 17 February 2012

20 Introducing ETCS with STMs, Conclusion The STM concept does not seem to solve most issues of the ETCS migration It rather leads to a life extension of existing systems due to the significant investment necessary onboard Better transition strategies are therefore needed to eliminate national system within a reasonable time after introducing ETCS. page 20 Wildenrath, 17 February 2012

21 Contents What ETCS is Introducing ETCS on a network Limited Supervision Mode ETCS Rollout in Switzerland Summary / Conclusions page 21 Wildenrath, 17 February 2012

22 Introducing ETCS As shown the installation of multiple onboard system according to the STM concept can be costly Better transition strategies than the STM concept are therefore required for the introduction of ETCS in many cases Parallel installation of ETCS and national systems trackside to allow both ETCS and national system equipped trains to run is costly too, in addition the potential of ETCS can not be fully utilised if another system is used in parallel (capacity / safety) The aim should therefore be to eliminate national system when introducing ETCS page 22 Wildenrath, 17 February 2012

23 Introducing ETCS Important cost savings can only be achieve if existing infrastructure can be retained / reused both trackside and onboard during the introduction of ETCS, protecting existing investments A lower cost variant of ETCS compared to full SIL 4 Cab Signalling should also be available, as the additional benefits of full ETCS (e.g. safety, capacity, high speed, cab signalling) are not required on many lines The Limited Supervision Mode has therefore been defined to achieve these goals page 23 Wildenrath, 17 February 2012

24 Limited Supervision Mode The Limited Supervision Mode can be described as follows: The Limited Supervision Mode provides a scalable version of ETCS in regards to safety and functionality The Limited Supervision Mode is a fully standardised ETCS mode, like any other of the modes (e.g. Full Supervision, Shunting, On Sight Mode) The Limited Supervision Mode is not a national solution SRS = system requirements specifications page 24 Wildenrath, 17 February 2012

25 Limited Supervision Mode The Limited Supervision Mode can be described as follows: Cab signalling has been eliminated in a first step This makes it possible to use existing trackside information that is not sufficient for cab signalling from either a safety or functional point of view (data not SIL 4 or incomplete) Supervision is then performed in the background, and the driver is operating the train according to the lineside signals The level of supervision is scalable, from full braking curve supervision to simple stop / warning / proceed functionality SRS = system requirements specifications page 25 Wildenrath, 17 February 2012

26 Limited Supervision Mode v=f(s) Interlocking ETCS LEU Eurobalises) Dual channel supervision Driver is following lineside signals LEU = lineside electronic unit Background supervision through ETCS on-board equipment Standard ETCS on-board equipment according to baseline 3 / 2.3.0d w/ CR 637 page 26 Wildenrath, 17 February 2012

27 Full Supervision vs. Limited Supervision Mode Data engineering Movement authority Speed profile Linking Information Gradients Safety level Indications On-board Trackside ETCS L1 FS Detailed engineering: - Completeness of data - Individual / specific telegrams - Considerable effort for verification, validation, testing Exactly measured Detailed Exact distance between balises Detailed gradient profile SIL4 Full cab signaling Standard ETCS EVC LEU with Eurobalise ETCS L1 LS Simplified engineering: - Data as far as required / available - Use of a standard set of telegrams - Minimum effort for verification, validation, testing Simplified, e.g. supervision of speed reduction Simplified SSP / permitted braking dist. Not required (optional) Simplified gradient SIL1 to SIL4 (depends on trackside data) Limited indications, use of lineside signals Standard ETCS EVC LEU with Eurobalise LS allows flexible and scalable ETCS implementation LS allows fast ETCS rollout by using standardized / pre-defined ETCS telegrams page 27 Wildenrath, 17 February 2012

28 Full Supervision vs. Limited Supervision Mode Comparison of DMI indications DMI for Full supervision DMI for Limited supervision Permitted speed Planning area Actual speed Actual speed Target speed Mode information Target speed Mode information Target distance page 28 Wildenrath, 17 February 2012

29 Full Supervision vs. Limited Supervision Mode Scalability of supervision functions and trackside equipment: Degree of supervision can be adapted according to the demands of the national signaling system (safety, performance) Range from simple train stop or warning functions up to FS functionality Not mandatory to equip all signals of a line to allow LS operation Examples for scalability: Line section with high potential risk: continuous speed monitoring + automatic brake application Line section with lower potential risk: warning information + speed supervision after a defined distance Line section with low potential risk : warning information and triggering of emergency brake when passing red signal FS = full supervision page 29 Wildenrath, 17 February 2012

43 Level 1 LS Implementation in Switzerland Optimized solution for stop / warning / proceed A special LEU has been developed for the large number of signals where only a stop / warning / proceed supervision is required (MiniLEU S11) with the following advantages: No external power supply required, zero power consumption Connects to existing relay contacts that control the SIGNUM, nor requiring any changes to the signal interface As a consequence very fast installation and commissioning, minimizing impact on operation Significantly higher safety level compared to existing SIGNUM through failure detection and self testing page 43 Wildenrath, 17 February 2012

44 Level 1 LS Implementation in Switzerland Optimized solution for braking curve supervision An improved version of the already proven LEU, the S21 MS has been developed to cope with some of the issues of the L1 LS rollout: Engineered data stored in external cartridge Reduced time for programming Extended diagnostics supports paperless commissioning page 44 Wildenrath, 17 February 2012

45 Level 1 LS Implementation in Switzerland Optimized engineering processes and tools SBB and Siemens have jointly optimized the whole engineering process, redefining the work split to minimize the number of both engineering and verification steps. Based on that Siemens optimized the whole tool chain used for engineering, installation, commissioning and verification. page 45 Wildenrath, 17 February 2012

46 Level 1 LS Implementation in Switzerland Optimized engineering tools The whole tool chain used by both SBB and Siemens has also been optimized and based on a common database. This allows to at least partially automate the engineering steps. Also many verification and validation steps can be automated. As a result the amount of work required for engineering can be minimized and the number of errors reduced. page 46 Wildenrath, 17 February 2012

47 Level 1 LS Implementation in Switzerland Standardized installation variants Standardized variants have been defined to replace the existing train control systems with LEU s where braking curve is required Where only stop/warning/proceed is required no changes to the existing infrastructure are required as the MiniLEU interfaces directly to the existing SIGNUM relay contacts Obsolete components are being removed during installation These measures help reducing installation cost, but also life cycle cost as maintenance is simplified page 47 Wildenrath, 17 February 2012

48 Installation of L1 LS MiniLEU Installation of one of the L1 LS MiniLEU prototypes used for extended field trials Key element of the Swiss ETCS rollout is the very fast conversion of all existing installations of ZUB and Signum to ETCS L1 LS page 48 Wildenrath, 17 February 2012

52 Installation of L1 LS MiniLEU :01 The new cable between the MiniLEU and the junction box at the signal mast is prepared for a fast switchover during commissioning. page 52 Wildenrath, 17 February 2012

53 Installation of L1 LS MiniLEU :22 Installation and cabling of all components finished, signal ready for commissioning after 1 hour and 7 minutes page 53 Wildenrath, 17 February 2012

54 Installation of L1 LS MiniLEU :00 to 13:08 Switchover from the existing Signum magnets to the MiniLEU including test and commissioning takes between 5 and 8 minutes. This can be done in regular traffic between train passages. page 54 Wildenrath, 17 February 2012

55 Installation of L1 LS MiniLEU The short installation and commissioning times are only possible due to the engineering and logistics concept applied. All components are prepared per signal in the factory, including programming of the MiniLEU, programming of the Eurobalises labelling of all components. page 55 Wildenrath, 17 February 2012

57 Level 1 LS Implementation in Switzerland Summary / Conclusions Only by using the Limited Supervision mode can the entire Swiss rail network be converted to ETCS within a few years The cost compared to ETCS L1 Full Supervision is significantly lower, as existing signal interfaces can be reused, minimizing the impact on the existing infrastructure The safety level will be significantly higher than with the existing legacy systems due to higher availability and improved functionality Full interoperability is achieved with Limited Supervision with any ERTMS equipped train page 57 Wildenrath, 17 February 2012

58 ETCS Level 1 Limited supervision Summary / Conclusions Limited Supervision is an integrated feature of the ETCS baseline 3 (or baseline 2 with SRS 2.3.0d and CR 637) It has been defined to provide a possibility of introducing ETCS at lower cost, mostly by reducing the engineering effort and by allowing reusing of existing interfaces and data that might not be sufficient for full cab signalling The effort required for verification, validation, testing and acceptance is also significantly reduced, and existing operational principles and rules can be kept The Swiss case proves that these goals can be met Limited Supervision can be the ideal first step when introducing ETCS on a network page 58 Wildenrath, 17 February 2012
