Transport Minister Dean Nalder announced recently the station was expected to be completed in early 2017, pushed back from late 2016.
He said the delay was due to work to widen the Russell Road bridge to allow better movement of cars and buses around the station and its 2000-bay car park.
Mr Cain said the delay was justified.
�The widening of the bridge over the freeway adjacent to the Aubin Grove rail station site was always an essential part of the necessary improvements to the local road access to and from the proposed parking areas for the station,� he said.
�The creation of approximately 2000 car bays for the rail commuters would have a severe impact on traffic delays in the area without the duplication of the bridge.
�Any minor expansion of the anticipated contract period to accommodate the bridge duplication is well worth the wait when looked at in the overall context of a much more functional traffic network following the introduction of the significant commuter parking areas for the rail station.�
Mayor Logan Howlett has been vocal in the past on the need to upgrade local roads, saying the station would fail on day one unless they are made.
He said the City is working with the Public Transport Authority�s station design team to produce a layout that is safe for vehicles, pedestrians and cyclists.
�The City will look at assisting the PTA with any improvement works to adjacent streets with municipal funds on a cost-sharing basis if there is demonstrable benefit to the ratepayers of the City in the future,� he said.
