4 1. INTRODUCTION. Political situation for ETCS deployment EUROPE: Community Directives developing the Railway liberalization Railways designed The High Speed European Network New interoperable signalling system was introduced: ERTMS/ETCS SPAIN: Relevant Political decisions: Fitting all new HSL with ETCS L1 & L2 Fitting all HST in order to run all over Spain: ETCS L1& L2 and STMs Open the market: equipments from all the track and onboard suppliers Maintain quality of service standards for high speed Consequences: Contracts with all UNISIG companies Target for commercial operation: full compatibility among HST and HSL Real interoperability: HST crossing borders everyday 4

5 2. ETCS DEPLOYMENT IN SPAIN From Unisig to real interoperability The ETCS implementation in Spain proved cross compatibility is real The first ETCS system validation was made under the most complex conditions: HSL: Madrid-Lleida (part of Madrid-Barcelona line) Trackside equipment: Ansaldo-CSEE Transport HST: Class 102 from Talgo-Bombardier Onboard equipment: Siemens Simultaneous validation for vehicle and infrastructure How did we manage? New validation procedure Test campaign at CEDEX Lab Harmonization process involving all suppliers More than km field test 5

8 3. ETCS ONBOARD EQUIPMENT. Some important issues Braking curves: Safety relies on the appropriate selection of braking curves ETCS on-board equipment calculates braking curves based on: Traction/braking model Trackside information It is necessary to evaluate Safety Margin, taking into account: Train braking capacity and braking curves design Trackside design Odometry: SIL4 demands high accuracy requirements for odometry Current odometry solutions are based on wheel sensors and Doppler radars To fulfil safety requirements it is necessary to pay attention to: Architecture: component layout, algorithms, redundancy Radar performance under bad conditions: ice, snow, etc EMC Electromagnetic compatibility problems may appear, especially for existing trains 8

9 3. ETCS ONBOARD EQUIPMENT. Train interface ETCS-Train interface Several operational functions depends on vehicle topology EVC-TCN interface implementation allows: Automatic Train Operation (ATO) Redundant DMI TCN (Train Communication Network: MVB/WTB) Interface EVC/TCN Telegrams Antennas ETCS Safety functions EVC Odometry Boulean signal (1/0) Profibus Brake equipment Emergency brake Display DMI Signalling information ATO Traction and brake Display DMI Vehicle information and Signalling information in case of ETCS DMI failure 9

10 3. ETCS ONBOARD EQUIPMENT. Specifications evolution ETCS development ETCS implementation in Spain started in a non stable specifications scenario The specifications were updated during the ETCS development Additional effort required: Harmonization process involving all suppliers Drivers training Migration to new versions ( ) Operational Harmonization still needed. Some examples DMI: Safety information is harmonized Differences in operational information (messages, planning areas, etc) Data entry Different procedures: enter values or select data set System should avoid human error (minimize driver s responsibility): Checking data entered versus real train brake state 10

11 3. ETCS ONBOARD EQUIPMENT. Beyond the specifications Additional functionalities Increasing reliability and performance is possible beyond the specifications Some examples of solutions adopted in Spanish projects: Redundant DMI: Operation is still possible in case of DMI failure L0 + ASFA: Dynamic transitions to other signalling systems through National Functions JRU: Compatible data analysis tool 11

12 3. ETCS ONBOARD EQUIPMENT. Beyond the specifications Redundant DMI HST class 102/103: Diagnosis DMI used as ETCS DMI HST class 120: GSM-R DMI shared with ETCS in case of failure ETCS GSM-R 12

13 3. ETCS ONBOARD EQUIPMENT. Beyond the specifications National Function ASFA Management (Level 0 + ASFA): ETCS manages ASFA activation allowing dynamic transitions to ASFA lines without STM: Level 0: ETCS in service (all ETCS L0 functions active) + ASFA in service Level 1/2: ETCS in service + ASFA in stand by Transitions L0 + ASFA L1/L2: UNISIG compliant ASFA ETCS 13

14 3. ETCS ONBOARD EQUIPMENT. Beyond the specifications JRU: Interoperable Data analyser developed by CEDEX Initial specifications can lead to incompatible analysis tools Specific programs were required for each ETCS solution CEDEX developed a compatible tool. Vital to field test analysis CEDEX analyser Specific tools Select format: decodes data from different applications 14

15 4. HOMOLOGATION AND VALIDATION PROCESS Homologation scene Initial situation: No certification was possible due to unstable specifications It was necessary to develop a specific validation procedure: In accordance to EN 50126/ EN Parallel to certification process 15

16 5. COMMERCIAL EXPERIENCE WITH ETCS AND STM Madrid-Pamplona/Logroño/Irún ETCS L1 (277 km) and Level 0+ASFA 10 daily trips HST class 120 (250 km/h) S.Sebastián Irún Madrid-Barcelona (625 km) ETCS L1 32 daily trips HST class 103 (300 km/h) Valladolid Logroño Pamplona Zaragoza Huesca LLeida Barcelona Madrid-Valladolid (179 km) ETCS L1 10 daily trips HST 102 class (300 km/h) Segovia Madrid Camp Tarragona Madrid-Sevilla (471 km) STM-LZB 2 daily trips HST class 103 (300 km/h) Madrid-Zaragoza (307 km) ETCS L1 12 daily trips HST class 102 (300 km/h) Sevilla Málaga Córdoba Antequera Madrid-Málaga (512 km) STM-LZB 24 daily trips HST class 102 (300 km/h) 2 daily trips HST class 103 (300 km/h) Current situation: km/day under ETCS L km/day under STM-LZB Punctuality (5 delay): 98,82 % (all incidents considered, not only ETCS) 16

17 6. CONCLUSIONS ETCS in Spain now: Spain has the largest high-speed network in commercial operation with ETCS L1 Spanish Railway Administration is developing a huge programme for new lines and vehicles Very high quality of service requirements are fulfilled ETCS L2 validation is under process Experience to share: Cross compatibility among equipments from different suppliers Technical and operational compatibility with existing NON ETCS lines, through STMs or National Functions ETCS implementation process management Real interoperability is a fact 17
