Alas, some bright spark in the 50s sold off reserved land to the west of the line for houses. This is the reason the third track does not go to Cheltenham.
Why doesn't this surprise me!
Westfield are known for their antipathy towards public transport and providing facilities for the hoi polloi arriving by bus, tram or train. I think there's a certain thinking that if you can't afford a car then perhaps you aren't the right sort of clientèle for their centre. Personally I think 'why bother' - if Westfields themselves don't care about trying to increase their shopping centre patronage then why should the government care. It was another foolish 'me too' promise from Mulder et al that ultimately showed them up as untrustworthy though.
Particularly stupid as it was those Frankston line seats that cost them government - just like they did to Brumby.
I can imagine the cabinet meetings earlier this year where Napthine was trying to sell the line that "East-West will take care of everything, just stay on message...".
