ASA – purpose and core functions

• “Making it clearer and simpler– for Transport Cluster – for Supply Chain

• Enabling innovation • Fitness for purpose assets • Driving transparency • Values and customer focus

”


–

The “eight pillars” of engineering assurance


–

Purpose - why are w e here?

• Collaborating - industry and government • Produce a process…subsequent standard…for

signalling certification of rolling stock by AEOs • Clarity for rolling stock suppliers - their obligations for

the certification of their equipment • Enabling industry – AEO’s – to do more

Rolling Stock Certification Michael Uhlig, Lead Engineer Rolling Stock


–

Rolling Stock Acceptance The ASA rolling stock acceptance process follows the RailCorp acceptance process and covers all rolling stock including: • Freight wagons • Locomotive hauled passenger

wagons • EMU / DMU • Infrastructure maintenance vehicle

• Road rail v ehicles

• Trolleys, trailers, and quadracycles

s


–

NSW Network Acceptance

• Acceptance of rolling stock by ASA is only applicable for the RailCorp Network.

• Rolling stock acceptance on the ARTC Network is managed by ARTC .

• Rolling stock acceptance on the Country Regional Network (CRN) is managed by John Holland.

• Some operation may require acceptance on all 3 Networks in NSW and potentially other Networks across Australia.

• However, ASA and CRN/JHG have a mutual collaboration of rolling stock acceptance (with relevant local operating conditions).

ASA Rolling Stock Review – Signalling Specific ASA conducts a discipline SME stakeholder sign off for the review of rolling stock against the Minimum Operating Standards for Rolling Stock and any associated discipline standards referenced.


–

Minimum Operating Standards for Rolling Stock ( RSU’s)


• Contains general requirements for all rolling stock, in addition to specific requirements for certain types of rolling stock, for example, Locomotives, Freight Vehicles, Passenger Multiple U nit Rolling Stock.

• Contains infrastructure interface requirements for rolling stock

• Contains rolling stock performance requirements for infrastructure compatibility and basic safety.

• Refers to and is compatible with Signalling Standard T HR SC 00006 ST Rolling Stock Signalling Interface Requirements.

• Contains Vehicle Information Pack

–

Clarification / Testing

• Further clarification and / or testing may be required or requested, factors which determine this include: - New or novel rolling stock design - Differences in the submitted design - New manufacturer and / or different manufacturing batch / series - Existing testing not conducted to the required standards


–

• Mixing restrictions

Operating Conditions

Operating conditions based on information provided, tests results from static and dynamic tests, and Network capacity or limitations. As an example the following operating conditions may be included:

• Maximum speed or class • Maximum gross vehicles mass • Line, corridor, or structure restrictions• Maximum hauling capacity • Maximum consist sizes

• Vehicles are generally accepted and published with their operating conditions.


–

TOC Manual

The ASA Train Operating Conditions (TOC) manual is the current controlling document for vehicle accepted onto the RailCorp Network. The current version is the December 2015 reprint and is found on the ASA website in 3 parts: • TS TOC 1 : 2015 – General Instructions • TS TOC 2 : 2015 – Division Pages • TS TOC 3 : 2015 – Track Diagrams • Accepted vehicles are published in the General

Instructions section, sections 10, 11, and 12. • The TOC Manual is updated 3 times per year

(April, August, and December) and TOC Waivers are utilised for interim vehicle acceptance between reprints.

–

TOC Waiver • Waiver to the TOC Manual. • Time l imited – maximum 6 month

duration. • Permits various operations of rolling

stock between TOC Manual reprints, one off movements, test movements, special operations, normal operation , etc.

• Contains same information as TOC Manual.

TREG – The Future TREG – Train Registration. Part of a larger system for monitoring train condition of rolling stock on the RailCorp Network (WIMS) and currently contains basic vehicle acceptance capabilities.

The following details are currently being investigated: for – • Owners/operators submit vehicle applications online together with all supporting

documentation and select which Network to run on • Request is forwarded automatically to the relevant Network Manager or Owner. • Network Manager reviews and accepts vehicle • Vehicle is then published online (section 10, 11, and 12 of the TOC Manual will

be held in an online database). Publishing will be immediate upon Network acceptance

• This system is being developed with multiple Networks in mind as a National Database. Vehicle acceptance across different Networks will be clearly visible together with any local operating conditions

• Control of vehicle codes is maintained on a National scale • Vehicle approval process is recorded and filed for future reference • Different viewing/access privileges depending on operator, owner, maintainer,

Network owner

Risk Workshop


–

The question: What hazards need to be covered off on the new process

Examples:

• ASA does not approve the vehicle – rejects the recommendation

• The vehicle is accepted and then found to be incompatible

• Shortage of skilled Signalling resources to perform this work

• Commercial issues influencing the technical outcome


–

Certification Process - Alignment to EN50238

Dave Nolan, Principal Engineer Signalling Systems


–

Assurance

• The overall objective is to obtain assurance that a vehicle can be safely and reliably operated on the network

• The new process needs to embody this requirement

The Process


–

The Process Explained

• Planning - Cross acceptance analysis

• Execution

• Evaluation

• Approval


–

Planning Pathway

• Consider the value of cross acceptance - Shortened test program - Testing only types and configurations not

included in the original safety case

• Comprehensive test path


–

Analysis for Cross Acceptance

• Comparable railway

• Common specification requirements

• Auditable results

• Reputable performance

• Gap analysis → shortened test program

• Potential conflict given the philosophical differences in train testing versus signal testing


–

Planning

• Aims of testing

• Types of tests to be conducted - Degraded modes of operation

• What track circuits are to be tested - Selection of a test site

• Possession planning

• Network access

• Test equipment to use → test schematics


–

Execution

• Worksite protection arrangements in place

• Connection of test equipment

• Booking out of order Sig equipment - Trainstop suppression - Clipping of points

• Conduct the necessary tests

• Disconnect test equipment

• Restore and certify the signalling equipment


–

Evaluation

• Determine results against the pass / fail criteria

• Ensure that the results are valid

• Look for any non-conformances

• Manage the non-conformances

• Peer review → gateway to approval


–

Management of Non-Conformances

• Identify the cause

• Identify the boundaries of the event - Magnitude – worst case needs to be considered - What frequencies are being generated - What is the duration of the non conformance - How often does it occur

• Consider how this impacts on the track circuit equipment - Demonstration by theoretical & bench tests

• Develop safety case


–

Approval

• Test reports submitted, peer reviewed with recommendation / approval

- Interim approvals / briefing notes - Per track circuit class / route

- Route clearance – restricted approval - Must detail versions of traction control and related

software.

• ASA reviews test reports and if in agreement signs off on the TOC waiver


–

Modifications to T HR SC 0006 ST

• Provide a matrix of tests vs. vehicle types

• Listing of all track circuit configurations

• Listing of installed track circuit types per line

• Publishing maximum permitted track circuit occupied voltages

• Some high level requirements for test sites - Near a traction supply substation - Tangent track - Easy access

• Guidelines for cross acceptance?


–

Accountabilities

• ASA’s primary role is to obtain the assurance of the vehicle’s compatibility

• The Test agency’s role is to determine that compliance

discuss


–

In Conclusion

• Take onboard today’s inputs / considerations

• Compile a new Standard - Subjected to ASA’s normal production process - Risk assessed - Level 2 – circulated to industry for comment

• New entry on the AEO matrix - AEO assessment
