• A ‘black spot’ in the DTRS network, resulting in a significant safety issue in the event of anemergency call or a train incident.• The increasing maintenance costs of the MetroNet facility and the limited reliability foradequate operation for the next 10 – 15 years.None of the existing communications facilities were in a suitable position or offered the requiredheight to provide adequate coverage to the rail network, and as such were not selected for thisproposal.Other infrastructure options were considered, but were not feasible for the proposal.• The proposed monopole is less obtrusive, requires less space and will be cheaper tomaintain than a lattice tower or guyed mast. A monopole also uses a foundation designthat is better suited given the spatial limitations within the rail corridor. The monopole isthinner at the top and less obtrusive than a lattice tower, helping to minimise the visualimpacts of the proposal.• The monopole can be installed using a hinge mechanism, which removes the need forlarge cranes.The installation of a walk-in equipment hut would use more space and be more expensive. Theuse of outdoor cabinets was the most suitable solution given the limited space, cost andminimisation of environmental impacts.Radio frequency modelling also indicated that a new DBS further west of Hurstville Stationwould not provide adequate coverage to the rail corridor.3.6 Justification of the Preferred OptionIt was decided to construct a DBS at the proposed location because it will enable the site to beconsistent with the whole DTRS network. Consistent technology choice will enable TfNSW toimprove its existing quality of service, reliability and emergency responsiveness. The reasonsfor selecting the technology are discussed above.The Hurstville West Portal site was selected due to its ability to cover the section of trackbetween Carlton and Penshurst. The proposed antenna height of nine metres is the minimumheight required to provide optimum radio frequency coverage for these sections of trackThe proposed site is also close to existing fibre and has good construction and maintenanceaccess. The proposed work will not require the removal of native vegetation.The proposed Outdoor Location 2 is located near the Apparatus Room west of the station. Thesite accommodates the equipment, has ready access without the need for scheduled trackpossession and provides a local power source.Page 30 of 75
In summary, a higher pole, or an additional DTRS facility would be required if the site was to berelocated. It was decided that the preferred option would offer the least impact on the localenvironment while still meeting operational requirements.Page 31 of 75
