Warrawee Substation - Review of Environmental Factors

The proposalsubstation would be required in this section of the rail corridor. The selection of thissite was further constrained by existing rail infrastructure (air gaps, overlaps, trackgeometry, signals layout), availability of land of sufficient size, future planned raildevelopment and retention of adequate access past the location for ongoing trackmaintenance operations.Alternate sites within the rail corridor both north and south of the Brentwood Avenuesite were considered, however due to space being minimal and the presence ofvegetation, such sites were not considered appropriate.2.2.2 Justification of chosen optionThe ‘do nothing’ option was not considered a viable option as it would result in therebeing insufficient power supply along this section of the rail network to accommodatethe predicted future demands. This would result in substantial adverse impacts on theoperation of the rail network.The option to construct a substation at Brentwood Avenue, Warrawee is the preferredoption as it would be positioned in the section of the network which was identified inthe modelling as requiring additional coverage to ensure that the network isadequately powered. The site at Brentwood Avenue would provide adequatescreening from surrounding land uses due to vegetation located just outside the railcorridor.Warrawee Substation Project/Review of Environmental FactorsPage 17 of 64
