  • 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?

    LIGHT RAIL

    SYSTEM

    OWNER

    GOVERNMENT

    COUNCIL

    OPERATOR

    MAINTAINER

    DESIGN

    CONSTRUCTOR

    USER GROUP

    UTILITIES

    COMMUNITY

  • 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
