Dr. Frank Heibel, Director, Doc Frank Pty Ltd - Update on the application of European Train Control System (ETCS) technology within Australia

  1. 1. Update on the Application of ETCS Technology in Australia Telecommunications & Train Control Conference Sydney, 11 August 2014 Dr Frank Heibel
  2. 2. Content • Context and purpose of ERTMS and ETCS • From Europe to Australia • Status of ETCS in Australia • Technology selection • Three key considerations • Outlook • Questions and Discussion Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 2
  3. 3. ERTMS and ETCS ERTMS (European Rail Traffic Management System) = • ETCS (European Train Control System) • GSM-R radio for voice and data (for ETCS Levels 2 & 3) • ETML (European Traffic Management Layer) – all but forgotten Purpose of ERTMS: • Enhance cross-border interoperability in Europe • Harmonise more than 20 incompatible legacy ATP systems (and many national legacy radio systems through use of GSM-R) • Note: Capacity increase was no specific design objective Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 3
  4. 4. ETCS Signalling Levels ETCS Level 1 • Intermittent data exchange • Infill for early authority updates • Overlay requiring signals Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 4 ETCS Level 2 • Continuous data exchange • Requires GSM-R data radio • In-cab signalling (ETCS Level 3) • Moving block, train determines its position and integrity (no track circuits) • Not specified yet, no standardised products, only “interpretations” of FRS Diagrams from www.ertms.net
  5. 5. ETCS in Europe Key stakeholders: • ERTMS Users Group formulates requirements • European Railway Agency ERA = System authority, CCM • UNISIG (supplier consortium) develops Specs Application / Rollout: • European legislative mandates ETCS • Strategic focus on Ten-T corridors • Commonly overlay application on top of Legacy ATP • State rollout plans over decades Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 5
  6. 6. Why ETCS in Australia Trend to introduce ATP and/or upgrade existing signalling to: • Increase safety (where no or insufficient ATP) • Enhance capacity provision • Increase reliability (on time running) • Reduce field equipment (optical signals) ETCS is attractive technology due to: • Open supply market with established local base (including all founding members of UNISIG) • Maximum certainty of long-term system support • Competitive pricing Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 6 Waterfall 2003
  7. 7. ETCS Application in Australia ETCS Level 1 at forefront due to easy overlay • Auckland – Britomart to Onehunga • Adelaide – Seaford line (Belair line from E2014) • Sydney (outer suburbs, starting Wyong to Asquith) • Commonality: ATP introduction without capacity uplift ETCS Level 2 to exploit benefits of in-cab signalling • Sydney (for inner corridors, aligned with Level 1 program) • Brisbane (BAT -> entire network) • Commonality: Capacity increase to 24 trains per hour Reasonably widespread, but no full uniformity • ATMS piloted for interstate network • CBTC for Sydney Rapid Transit, Melbourne and Perth • Pilbara mining railways with bespoke solutions Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 7
  8. 8. Technology Selection The ‘Highlander principle’ does not apply – Why? • Fundamental differences between rail operations across Australia (compared to much more homogenous railways in Europe) • ETCS not equally suitable everywhere • ARTC: Rollout deemed unaffordable, Traffic management paramount • Sydney RT, Melbourne & Perth require capacity beyond 24 tph, calling for CBTC (capacity demand is paramount for city railways) • ‘Pilbara Rail’: Bespoke requirements without need for interoperation Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 8
  9. 9. Technology Selection (2) Key selection criteria for city in-cab signalling – “three C’s”: • Capacity (reliable operational capacity -> reserves for recovery) • Compatibility (fit to infrastructure and operations, migration path, …) • Cost • Capacity drives technology selection (is ETCS sufficient?) • Capacity need influences compatibility assessment • Capacity and compatibility prevail cost Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 9 Rail Operation Capacity Compatibility Cost Selection Sydney NWRL > 30 tph Ok for CBTC CBTC Sydney Suburban 24 tph ETCS ETCS cheaper ETCS L2+ Melbourne 28-30 tph Adapt for CBTC CBTC Brisbane 24 tph ETCS ETCS cheaper ETCS L2 / L2+? Perth 24-30 tph Adapt for CBTC CBTC
  10. 10. Consideration 1: Interoperability Different contexts and purposes: • Within same rail authority (multi-vendor, go-anywhere) • Between rail authorities (but only where needed) Practicalities of the multi-vendor argument: • Auckland: Single supplier • Adelaide: Siemens-Invensys ‘in-house’ IOP, only one more line to equip • Sydney: Single supplier for Level 1; Level 2 to be seen (per corridor?) • ETCS interoperability does not come by default, but requires work Interoperability between authorities: • Dual fitment of trains or interface development between systems • ATMS and ETCS were not designed to interoperate with each other • Close alignment needed between ETCS authorities (e.g. Sydney-Brisbane) Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 10
  11. 11. Consideration 2: Capacity Achievable capacity gain from ETCS differs between routes • Requires additional work e.g. on block section layout (overlap lengths) • Network modelling advisable for line specific assessment • ETCS Levels 1 & 2 were not designed for capacity uplift Capacity gain is limited • Study: Level 1 with shortened overlaps adds 2 tph, Level 2 another 2 tph • May be impacted by many aspects, most notably ETCS braking curves and radio transmission delays (for Level 2) New developments required for reliable capacity gain • Ongoing product development for latest ETCS SRS (‘Baseline 3’) • Baseline 3 includes e.g. braking curve optimisation • Current development of enhancements (e.g. ATO add-on, virtual block) • Reliability increase by reducing driving variability Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 11
  12. 12. Consideration 3: Telecommunications In-cab signalling solutions require specific data radio • Technology selection driven by capacity, not by existing data radio GSM-R still mandated for ETCS Level 2 • Circuit switched, but capacity issue less serious in Australia (15MHz) • GPRS (IP based, packet switched) is coming -> ETCS Level 2+ • Long-term evolution towards LTE expected CBTC does not work over GSM-R • Current applications based on WiFi (public or ISM band – unlicensed) • Does not utilise 1800MHz band allocated to railway use • Increasing risk of interference problems • Adoption of LTE in progress -> recommendable now or later? Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 12
  13. 13. Outlook ETCS has become most widely used ATP for mainline railways • Adopted in many countries outside Europe, including ANZ In-cab signalling (i.e. Level 2) required where capacity needed • Rollout in Sydney and Brisbane as budgets allow Current developments for ETCS Level 2+ recommended • Sydney plans for ATO to achieve highly reliable 24 tph capacity • Brisbane may need to consider it (even higher capacity requirements) Key challenges to overcome • Interlocking interface to avoid replacements, Interface for ATMS interoperability Strong business case if capacity uplift defers new infrastructure Update on ETCS Application in Australia Telecommunications & Train Control, Sydney 11 Aug 2014 - 13
