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.

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

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.

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.

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 2. Reasons for Higher Levels of Automation – increased Safety

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) Specialist Disciplines do not align with overall functionality requirements – f.i., response to tunnel fire: In an integrated system these functions can be heavily automated to avoid overloading control room staff 2.

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.

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. 3. Benefits of Integrated System Approach

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

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

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

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.

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

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.
