^^ from the article:
Transport Minister Rita Saffioti said it was a quality deal for the state and they had learned lessons from other Australian governments who had gone overseas to build new railcars.
"By bundling multiple railcar orders into one super-contract, we have encouraged the market to make very competitive bids for the work," she said.
"Victoria has moved to this policy many years ago,
Queensland is spending hundreds of millions to correct railcars that were fully imported.
"NSW has also had its problems so we're very proud of this policy, I would argue the value for money concept any day of the week with anyone because these are cheaper railcars, quality railcars and one built for WA.
