Speaking to someone inside the PTA the other day, it will probably be about Feb or March next year before any serious work is begun. Something to do with the fact they are still finalising some of the tunnel design in term of new regulations required for tunnels.
Ok Ladies and Gents..here is the gos on how the construction will work. Stage 1: Early March 2010 will see the start of the platform 6/7 refurbishment which will include re-tiling etc. This will mean all Fremantle services will run from platform 8. Concludes approx Jan/Feb 2011. Old platfor 1 will be renamed platform 11 and exteded up to 150mtrs to hold a 6 car set. Armadale peak will use platform 6 west (opposite 8) Passenger access to 8 will be via the western concourse
. The old timber footbridge will be dismantled and the construction of a new underpass between platform 5 & 6 will commence.
