3.3 Response to submissions3.3.1 Why is the substation being constructed in the area chosen? Hasthere been research into an alternative location?Issue Addressed: Location of SubstationAddressing Submissions: 2, 3, 5, 8, 11, 12, 14, 15, 19, 21, 22, 23, 26, 27, 28, 30, 32, 33, 34, 37, 38,and 39.RailCorp is undertaking a program of works across Sydney to increase the capacity andreliability of the electrical network. The TSU program is delivering vital enabling works tomeet the power requirements of the new Waratah fleet, and to support the transition to 100%air-conditioned fleet with all trains becoming 8-car sets.Based on the power requirements of the new and existing rolling stock, RailCorp modelled thepower demand by undertaking a number of power studies across the network to identifyinfrastructure that would require upgrading. The assessment of the electrical network on theNorth Shore Line found the existing section between Gordon and Hornsby would not meet theexpected power requirements without an additional substation between Turramurra andWarrawee.Section 6.4 of the TSU Power Study 5 Scope of Works (Version 1.03) dated 17 January 2008States:A new 2*5MW substation is to be built at Warrawee. Existing early designdocumentation indicates tat that the substation shall be built at NS21+460 and theTurramurra Section Hut shall be decommissioned. The proposed Warraweesubstation shall feed the same overlaps as the existing Turramurra Section Hut.Substations are required to be located within 200 metres of the overhead wiring connectionpoint to minimise the potential for arcing (sparking) between the different sections of theoverhead wiring (resulting from voltage variances that occur in long lengths of cable) thatcould cause the overhead wiring to burn down.If there is not a suitable location within 200 metres either side of the overhead wiringconnection point RailCorp would have to undertake an extensive analysis to identify a feasibledistance to locate the substation from the overhead wiring connection point. The analysisconsiders the effects of the rolling stock power requirements, topography of the rail line, timetabling including train frequency and stopping patterns, tack layout and surroundinginfrastructure that interfaces with the earthing system of the substation.Turramurra Sectioning Hut is located on the eastern side of the rail corridor between CherryStreet and Brentwood Avenue at Warrawee. It connects to the overhead wiring at 21.28km to21.34km from Sydney Terminal.RailCorp assessed the rail corridor within a 400 metre building envelope (200 metres eitherside of the required overhead wiring connection point) for suitable locations to place theproposed substation. The assessment confirmed that there were no suitable locations on theWestern side of the corridor due to construction and access difficulties associated with thesteep embankments and in close proximity (less than 5 metres) to adjacent residences. Therail corridor on the Eastern side of the corridor, near the existing section hut was found to betoo narrow and in close proximity (less than 5 metres) to adjacent residences in CherryStreet.The only site within 400 metre building envelope that can accommodate the proposedbuilding is the parcel of land on the Eastern side of the corridor at the end of BrentwoodAvenue. This site has the advantage of being furthest away (approx. 20 metres) fromadjacent residences. The site also provides access for ongoing maintenance.Page 15
Given the analysis to identify distances beyond the 400 metre building envelope takes inexcess of six months to complete, utilises scarce critical resources and there is a suitablelocation within the 200 metres of the overhead wiring connection point, RailCorp considersthe Brentwood Avenue site as the only suitable site from an engineering and the optimum sitefrom a community impact perspective.3.3.2 How will RailCorp ensure our properties will not be impacted uponby construction activities or the operation of the substation?Issue Addressed: Construction Noise and Vibration, CompensationAddressing Submissions: 1, 3, 5, 7, 12, 17, 19, 24, 26, 29, 30, 34 and 39.A property dilapidation report will be provided to the immediately adjacent residents, prior toconstruction commencing and at the completion of construction works. It is not expected thatthe construction works will cause any structural damage to properties in the immediatevicinity, however if final dilapidation report indicates damage due to project works, these willbe repaired.If residents feel that damage has been caused to their property (during the constructionperiod) as a result of construction activities, RailCorp will carry out an inspection comparingresults to the initial dilapidation report and any damage due to project works will be repairedby RailCorp.3.3.3 The areas around Brentwood Ave and Hastings St are frequentlyused by many school children and their families not only foraccess to local schools but for travelling by rail to other schoolsalong the line. How will RailCorp ensure their safety?Issue Addressed: Pedestrian Management and SafetyAddressing Submissions: 1, 3, 6, 7, 8, 14, 17, 18, 19, 22, 24, 26, 28, 29, 30, 33, 34, 36, and 39.RailCorp has outlined the control measures in section 3.12 of the REF ‘Traffic & Access.’The following control measures would be implemented to minimise impacts on the traffic andtransport network:• A traffic management plan would be developed in consultation with Council to detailtraffic control measures along Brentwood Avenue and Hastings Road. This would beincorporated into the construction environmental management plan;• Access along the pedestrian path adjacent to the corridor to be maintained at alltimes during construction;• A designated heavy vehicle route would be identified within the traffic managementplan. Heavy vehicles accessing the site would be required to use this route;• Vehicle movements to and from the site to be minimised during school start and endtimes;• Liaison with Ku-Ring-Gai Council is required to confirm the design, location andapproval requirements for the proposed site accesses;• Signage and traffic control devices would be installed to alert motorists andpedestrians to changes to local traffic conditions during the construction period; and• Oversized vehicle movements would be discussed with RMS and NSW Police prior tothem occurring.RailCorp will discuss with Council the option of extending the footpath in Brentwood Avenue.No members of the project team will be permitted to park within Brentwood Avenue, and notrucks will park in the street (with the exemption of special loads). In this regard, there will bezero tolerance to workers vehicle problems in Brentwood Avenue.Page 16
