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.

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

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

2. Reasons for Higher Levels of Automation

• Increased levels of safety - particularly during emergencies and failures

• Diagnose and Maintenance improvement

• Cost saving… and prestige

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 managementPlatform screen doors are one method of

enhancing safety.

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.

• 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

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.

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.

Many thanks for your kind attention.
