Developing Best Practice in Light Rail EngineeringMatt Rose – Engineering Manager DownerDaniel Caldwell – Design Manager WSP | Parsons Brinckerhoff
- Current status
- What is Best Practice?
- Importance of Stakeholders
- Light Rail Standards
- Interaction between road and rail
- Rail systems engineering and integration
- The urban environment
- Critical success factors
OUTLINE
- Multiple existing systems across the country- Unprecedented growth & rejuvenation- Different types of systems- No Australian Standards for Light Rail- Inconsistent delivery models
CURRENT STATE OF AUSTRALIAN LIGHT RAIL SYSTEMS
- More consistent approach to delivering light rail systems- learning from past and current projects- Integration and expansion of existing systems- Stakeholder expectations and input- Whole of life optimisation- Positive contribution to urban renewal projects
WHAT IS BEST PRACTICE?
IMPORTANCE OF STAKEHOLDERSWho are the Stakeholders?

WHY DO THEY MATTER?
What have we learnt?- Safety- Managing project and residual
risk (early acceptance)- Defining business and system
requirements- Defining interfaces and overlaps- Efficient & collaborative
approval pathways- Integration of assets- Meeting safety assurance
requirements- Asset ownership and
maintenance requirements
- No specific Australian Standards- EN standards widely adopted but
not always fit for purpose- Hierarchy of standards
§ Business and System Requirements
§ Project Specific Requirements
§ Local and State government standards
§ International and proven standards
- Rollingstock specific requirements – each vehicle is different
- Need to consider Operations and Maintenance (O&M)
LIGHT RAIL STANDARDS
- Light rail operational modes- The boundaries of asset ownership and standards is sometimes
undefined- Shared use – maintenance, emergencies services, pedestrian
movements- Clearances and separation (no consistent standard)
INTERACTION OF ROAD AND RAIL ENVIRONMENTS
Defining the system requirement
Concept of Operations and System Requirement Specification
Complex interfaces between: - Communications and security- Control Systems and
Signalling- Power Systems and SCADA- Electromagnetic Compatibility
RAIL SYSTEMS ENGINEERING AND INTEGRATION
Key is to define business and user requirements –agreement with stakeholders- SCATS- Utility providers- Operator- Rollingstock vendor
- Balance between user requirements- Human factors and risk assessment- Future planning – Urban integration- Wayfinding- Modal shift – improving connectivity between public transport
INTEGRATING ENGINEERING REQUIREMENTS INTO AN URBAN ENVIRONMENT
- Industry body- Develop common set of Australian
Standards for Light Rail
- Light Rail system owners- Early engagement with stakeholders- Limits of asset ownership- Clearly defined specification /
requirements
- Designer / Constructors / Rolling stock suppliers / Operators
- Improved definition of scope split
- Positive urban and community outcomes
CRITICAL SUCCESS FACTORS
