  3. Index • Traditional approach to designing railway control systems • Reasons for higher levels of railway automation • Benefits of an Integrated systems engineering approach • Some examples – Madrid, Hong Kong, Porto, Vancouver • Implications of these ideas for the purchaser • Summary Invensys proprietary & confidential

  4. 1. The Traditional Approach to Designing Railway Control Systems • Early railway engineering led by invention of new devices • Developments driven by technology • Railways were the “high-tech” field of the age • Railways were “engineering led” This useful looking device is an early version of an ERTMS beacon. Invensys proprietary & confidential

  5. 1. The Traditional Approach to Designing Railway Control Systems • Railways grew and organisations developed • Engineering Departments became specialised • Each Engineering Department had specialist experts • Equipment became more specialised and staffed by experts in their own fields Traditional departmentalised structure Invensys proprietary & confidential

  6. 1. The Traditional Approach to Designing Railway Control Systems - Problems • Traditional specialist disciplines do not align with overall functionality requirements • Traditional architecture requires interface control between disparate systems • Traditional architecture imposes constraints on total system response Invensys proprietary & confidential

  7. 2. Reasons for Higher Levels of Automation • Increased levels of safety - particularly during emergencies and failures • Diagnose and Maintenance improvement • Cost saving… and prestige Invensys proprietary & confidential

  8. 2. Reasons for Higher Levels of Automation – increased Safety DURING NORMAL OPERATION • Observing the Guideway - automatic obstacle detection and intrusion detection. • Passenger Transfer - passenger door control and platform edge detection. • Train status management Platform screen doors are one method of enhancing safety. Invensys proprietary & confidential

  9. 2. Reasons for Higher Levels of Automation – increased Safety DURING EMERGENCIES AND FAILURES • Detection and Management of Hazardous Situations • Train diagnostics • Fire and smoke detection and management • Emergency Handling – terrorism, earthquake (including automated evacuation announcements) Understanding the incident enables accurate and appropriate action. Invensys proprietary & confidential

  10. 2. Reasons for Higher Levels of Automation – increased Safety • Self-diagnose of hardware and communications status • Registration and reconstruction (“replay”) of all sequences of all events • Remote implementation of - software upgrades - tests - changes in layout

  11. 2. Reasons… - Cost improvement and prestige Specialist Disciplines do not align with overall functionality requirements – f.i., response to tunnel fire: • Position of trains and service reorganisation (ATS) • Tunnel ventilation fans (EMS) • Isolation of traction power (Power SCADA) • Closure of stations (BMS) • Public Announcements (PA) • Situation Monitoring (CCTV) In an integrated system these functions can be heavily automated to avoid overloading control room staff

  12. 2. Reasons…- Cost improvement and prestige Traction subestations Passenger stations Operational Control Centre OCC Interlocking Ticketing,ventilation…BMS Traffic Operator Power Operator Local Control Panel Supervisor Post CATENARY CIRCUIT BREAKER - SCADA Maintenance Centre FIBER OPTIC (DOUBLE WAN) Radio GSM-R Radio GSM-R JTCs, pumping,…EMS Depots and yards Trains Train’s antennae Signals Interlocking Track LCP BRAKES TRACTION DRIVER’S HMI On-board ATC Point machines Integrated System

  13. 3. Benefits of Integrated System Approach • Use of one integrated control system simplifies complex interfaces • It ensures a co-ordinated response to emergency situations • It ensures that all relevant information is available in one location – the OCC • Reduced Initial Investment • Accommodates Business Expansion Integrated systems provide the management of information from corporate HQ to stations.

  14. 3. Benefits of Integrated System Approach • Increased Operational Efficiency • Reduced Operator Error • Increased Multi-skilling of Operators and Maintenance Staff • Efficient incident management • Reduced Time-to-Clear an Incident • Simplified Operator Work Environment • Reduced maintenance costs A common “look & feel” operator interface for all sub-systems can provide many benefits.

  15. 4. Metro de Madrid – Alto del Arenal OCC Local legal regulations may avoid operators integration

  16. 4. Kowloon Canton Railway Corporation The first completely integrated control solution in the world… • 1 Million passengers per day • Track length: 53km • A train every 2.5 minutes Integration has allowed KCRC to operate East Rail with 3-5 operators.

  17. 4. Porto commuter network, Portugal • Porto urban & northern lines • 20 operational posts • Track length: 460 km • Commissioned in 2008

  18. 4. Canada Line Project in Vancouver • Greenfield project • 16 stations • SIL2 required for underground stations • Unmanned operation • Completed for 2010 Winter Olympics Total system integration was the requirement for this greenfield project.

  19. 5. Implications for the System Purchaser • Higher levels of automation benefit from a careful definition of the required functionality for the control system • The functionality needs to consider both normal and emergency operation • The definition of functionality should be considered independently of the traditional engineering disciplines • There are diagnostic & maintenance advantages in using an integrated control system which controls all relevant system elements. • Need to take into account legal regulations – external consultants with integrating experience might be helpful

  20. 6. Summary • The traditional approach of separate engineering disciplines being designed by their own experts has been successful for traditional railways. • Railways with higher levels of automation need to exploit that automation to derive Safety and Maintenance improvements. • Using traditional methods of design for these non-traditional railways is very likely to result in sub-optimum systems. • Using an integrated control system approach, covering all the traditional disciplines, will deliver a system with superior performance at a lower cost.
