VICERS PROJECT:A Major Safety Initiative
The objectives are to install VICERS on trains within the agreed parameters, being:
• Nomorethan2sixcarconsistsoutofserviceatanygiventime.
• UnitsfittedwithVICERSwithinatwodayturn-around(subjecttoachievingtheFitforInstallCertificate).
• Makeefficientandeffectiveuseof‘TestDriver’Crew.
• VICERSinstalledattheBrightonBeachSiding.
• TrainstestedandcertifiedFitforServicewithVICERSisolated,priortoreturnintoservice.
ObjectiveCaravel Group, was engaged by the Victorian Department ofInfrastructure(DOI)andConnex,toprojectmanagetheinstallationofaVigilanceandEventRecorderSafetySystem(VICERS)onallsuburbantrains.Caravelwasselectedfortheirexpertiseandproventrackrecordintherailindustry,havingsuccessfullydeliveredsimilartechnicalandsafetyorientatedprojects.
The installation ofVICERS required train units to be taken fromserviceanddeliveredtotheinstallationsite(BrightonBeachSiding)for fit-out, testing and return to service. This process althoughappearingstraightforward,wasimmenselycomplex,presentinghighlevels of difficulty and numerous constraints. Taking units out ofserviceforanyperiodoftime(nomatterhowshort)isaconsiderablechallengeinaculturedrivenbyan‘on-time’runningrequirement.
Withdetailedanalysis,planning,muchstrategisingandnegotiating,theCaravelProjectTeamsuccessfullycraftedandimplementedaplanaddressingthelogisticsofhowtoidentify,selectandtransferatrain.Beingheavilydependentonhumanintervention,theprocessrequiredclose oversight andmicro-management to ensure that at any givenpoint itdidn’t faildue to lackof visibilityorpriority. TheProjectwas successfully able to ensure that trainsmoved in andoutof theinstallation site in a timely and safemanner whilst simultaneouslybeingabletoboastanexceptionalqualityrecord.

AkeyrequirementoftheTrainLogisticsManagementPlan(TLMP)was to address logistical constraints.

• Trainaccess conflictwithotherprojects (conflicting schedulingand procurement). Advance scheduling, and constant liaisonwithPassengerFleetMaintenanceandNetworkOperationswasessentialtomitigateagainstthispotentialissue.
• Driver availability to meet the project circulars. To addressthis constraint a specific ‘TestDriver’Crewwas identified andallocated to theproject.However limitationof driver resourcesper this roster also created potential issues with restrictions totrainmovementsduetorelianceonqualifiedcrew.
• Preparation of Circulars (potentially a daily requirement) toensure units requiring VICERS installation were delivered asrequired.This constraint was resource-dependent and, so longas advanced planning and dedicated resources existed, it wasmanageable.
• Trainmaintenancerequirementsrestrictingallocationofrequiredunit for installation. To address this constraint, requirementscouldn’tbemadeforaspecificconsistbutratherforanyoneofanumberofconsists.Duringthetailendofinstallation,negotiationandadvancedplanningbecamecritical.
• Network related activities that affected the route (plannedand unplanned) including track occupations (as identified anddocumented by the Timetables group). Awareness of plannedactivitiesandon-goingcommunicationwithNetworkOperationswasessentialinmanagingthisconstraint.
• Fixedproductioncapacityduetoprojectcommissioningprogram(limitedorno‘catchup’opportunities).
• Tail-endof the installationprogram,whereby residualunits aredifficulttolocateanddifficulttodeliver,affectingtimelyaccesstotheremainingunitsforfitout.Planningandtrainconfigurationmanagement was essential to ensure that trains requiringinstallation ofVICERSwere tagged early and kept ‘in sight’ toensurethattheywerenotlostinthesystemand/orwithdrawnforotherpurposes.

Key Criteria for Train Movements
How OTR Manifests as an Operational Delivery RiskA key train delivery risk that posed a constant threat for theproject was the OTR requirement. OTR creates constraints onunit availability for installation purposes (i.e. all units required tosupplementthefleettomeetOTR).
Although technically, this OTR constraint was negated by theprojectobtainingawaiverfromtheDOIenablingtheProjecttohaveaccessto2six-carconsistsforinstallationpurposesandremovinganypenaltiesthatthissetutilizationapproachcouldincurforConnex.However,evenwiththewaiverinplacetheprojectfacedconstraintsfrom a behavioural (culture and mentality) perspective, wherebyinstinct would lead to trains being held back rather than handedoverforinstallationpurposes.Thisissuewastreatedthroughongoingcommunication, promoting the agreements and project objectivesandsafetybenefits.
Capping On-Time Running (OTR) at the Network Average Due to the removal of units out from service for the purposes ofVICERS installation, the project placed a constraint on Connex’capacitytomeetits‘OnTimeRunning’deliverable.Atthetimeoftheprogrammecommencing,OTRwasapproximately93-94%.Thiswas likelytodropduetotherequirementfortrainstobeallocatedtotheprojectratherthanbeing‘in-service’.ItwasexpectedinlightoftheabovethattheprojectwouldonlybeabletodelivertrainsataratenobetterthanthenetworkOTR.Forplanningpurposesarateof90%wasallowedfor.
Risk Management of Train Logistics To address the risks associated with the logistical planning andmanagementoftrainmovementsforinstallationpurposes,theprojectdevelopedaTrainLogisticsRiskManagementPlan.ThisplanwasasubsectionoftheTLMPandsoughttoaddresstheplanningofunitexchangesandtheimplementationrisksassociatedwiththeTLMP.
Maximising the Transfer WindowToreducetheimpactofresourcesanddemandsoftheprojectonthebusiness,transferwindowsfortrainmovementsweresetatspecifictimes(outsideofpeakandotherhightraffictimes).Thiswasdonewithanexpectationthat theorganization’sability todeliver trainswouldstayinthetargetrangeofgreaterthan90%.
Train Availability and Delivery ConsiderationsTheprojectpredicatedunitavailabilityontheassumptionthatfactorssuch as special events, occupations and driver roster requirementswerefullyconsideredintheTLMPinordertomeettheinstallationphasescheduleoftheproject.
Assuch,theprojectalsorecognizedthatunitavailabilityanddeliveryconsiderationsneeded to factor in a requirement forFleetControlinconjunctionwithUMTLtotakestepstoensurethatsetswhicharrivedatBBHSidingdidnot:
• AlreadyhaveVICERSfitted;or
• Have maintenance faults which would prevent the successfulinstallationofVICERS.
Creating a Window for Production ‘Catch-Up’Given the number of considerations and constraints imposed onthe project, it was prudent to ensure that some flexibility in theinstallationschedulewasafforded.AssuchabufferwasbuiltintotheprogrammeandtheTMLPwhichallowedcatch-uptooccurduringrestrictedtimetableoperations(suchasChristmas).
Thisbuffertechnicallyofferedthesupplieranopportunitytorecouplost time resulting from fleet unavailability during the scheduledprogram. Although the costof resourcingduring suchperioddidpresentamoderatingfactor.

Essentially, a provision has existed on other fleet upgrade/modification projects whereby drivers are involved in conductingpre-commissioningchecksonunitspriortotheirreturntoservice.

Managing Expectations
When Selection MattersFleetMaintenanceandFleetControlwere required toundertakea pre-selection check on units to ensure that those selected fortransfertotheVICERSprojectmetthecriteriasetbytheproject.Thecriteriaessentiallyrequiredthattheunitwascheckedfor:
• Status(i.e.ensureithadn’talreadybeenfittedwithVICERS)
and
• Defects
Establishing a Transfer ProtocolThe transfer protocol established made certain that a transferwindow was utilized and that checks occurred pre and postinstallationtoensurethatonlytheunitssuitableforinstallandsafetoreturnbackintoserviceweretransferred.
Handover from SupplierTheSupplierandUMTLconductedaHandoverCheckofthetrainpostthesupplierstaticandpseudodynamictestingoftheunit.TheHandoverCheckwasdocumentedbytheSupplierandsignedoffbybothparties.UMTLultimatelyhadtheresponsibilityforensuringthatthecheckwasconsistentwithanyotherhandoverchecksandmetinternalstandards,qualityandsafetyrequirements.
Once a unit was delivered to BBH Siding for installation it wasrequired to undergo a ‘fit for installation check’ (undertaken atBBHSidingbyUMTL).TheFitforInstallationcheckcertifiesthataunitisfreeofdefectsthatcouldimpactinstallationoftheVICERSsystem.UMTLconductedthefitforinstallationcheck,andiftheunitdidnotpass the test the trainwouldnotbe acceptedby thesupplier.

Following thehandoverof the train from theSupplier toUMTL,the trainsmust be checked and certifieddefect free (or acceptable35dayrundefectsasperoriginalclearance)suchthatthetraincansuccessfullyperformatestrun.
UMTLconductedtheFitforReturntoServicecheckandthetrainwouldnotbe acceptedby thedriver if it doesnotpass theFit forReturntoServicecheck.
Fit for Return to Service
Fit for Service CertificateUnitswerenotreleasedfromtheinstallsiteuntila‘FitforService,certificatewasissuedinrespecttotheVICERSinstallationworks.
Once the certificatewas issued from the installation site and theunits that were being fitted with VICERS release operations,anotherunitwouldbereleasedtotheprojectandtransferredtotheinstallationsite.
Duetothecomplexnatureofthisprojectthemonitoringandreportingassociatedwiththeprogrammewereofcriticalimportance.
Daily reportingwas essential and needed to be completed and theProjectManagerOperations(VICERSProject)keptinformedoftheprogressofthetransfers,andtheunitnumbersoftrainsfittedwithVICERS(asperthetrainmodificationrecord).
A core report used to identify and allocate units for VICERSinstallationwastheDailyOrderSheet,whichwassupplementedwithaVICERSTrainModificationRecord.Thesetwodocumentsformedtheconfigurationbaselinerecord.
The Project was responsible for maintaining a central VICERSmodificationregister(IDbyunitnumber).
AnydeviationsfromtheagreedprotocolsandcircularsneededtobenotifiedtotheVICERSProjectassoonaspracticable(i.e.priortoadecisionbeingmadeoractiontaken).
Monitoring and Reporting
Establishing a Driver ProtocolTheDriverswererequiredtofollowspecifictraindeliveryprotocoltoensure that the logistical transferprocessdidnotbreakdownatanypoint.As trainswere required to be checkedpre andpost theinstallation,with thepotential that aunit couldbe rejected at anypointintheprocess,itwasessentialforadrivertoremainwiththetrainthroughoutthetestingprocess.

Conducting Static & Dynamic TestingOnceVICERSwas installedontheunit theSupplierwasrequiredto undertake static testing. Testing was completed at the BBHSidingperthetestingplansandchecklistspreparedbytheSupplierinconsultationwithUMTLandtheVICERSProject.
Ofparticularinterestwasthefactthattheprojectaddressedalongstandingprecedentinwhichthe“rule”wasthatifthetrain’sbrakesweremodified in anyway at all then a full curve brake testwouldbe performed. Such a test required a major set-up exercise, tookconsiderable time to perform and consumed significant driver andtechnicalresources.

Dynamictestingwasundertakenbytestdriversinaccordancewithagreed test scripts in controlled environments with all the relevant approvalssought.
Accordingly,inadditiontotheSafetyRiskAssessmentmeetingsandtheOH&SandUnionConsultation series ofmeetings conductedas part of the BBHUpgrade, there was another parallel series ofmeetings involvingtheNetworkSafetyandOH&SrepresentativesfromConnex,UMTL, ElectricalControl (Electrol), the Supplier,andMainco,inordertodevelopasynchronizedsetofSafeWorkingMethod Statements (SMWS) and Safe Working Instructions(SWIs).FromtheSupplier’sperspective,theoverarchingdocumentresided with Connex, but a large number of other factors, e.g.Networksafety,electrical,signalling,fleetmanagement,etchadtobeconsideredtomanagethefollowingscenarios:
ForConnex:• Level 3 Safe-working Co-ordinator unlocking the site and

ForSupplier:• PreparationofSiteforTrainDelivery• WorkonTrainwithOverheadPowerDe-energised• WorkonTrainwithOverheadPowerEnergised• FitforInstallation• TestVICERSInstallation• SiteEvacuation• Service&RepairProcedure
InstallationofVICERSonunits required significantplanningandconsultationwiththevariousmaintenanceandoperationsgroupsinConnex aswell as theSupplier, externalMaintenanceGroups andtheDepartmentofInfrastructure.
Theprocesswas resource intensive and required extensive supportalongthewaytoensure thatbreakdownsatanyonepointdidnotinadvertently bring the programme to a stand-still. Due to the
complexnatureoftheorganisationandtrainoperationsatlarge,theplanningprocessrequiredin-depthunderstandingoftherailsystem,networkoperations,fleetmaintenanceandcrew.
