新州政府将兴建Parramatta到Macquarie Park的轻轨铁路

A LIGHT rail line from Parramatta up to Castle Hill and out to Macquarie Park is shaping as a likely 2015 Coalition ­election promise.

The government has ­already committed to a $700 million light rail line in Newcastle and a $2 billion line from the heart of Sydney past ­Central Station through ­Randwick to Kingsford.

Parramatta Council has put the cost of both lines it proposes at about $1.7 billion — less than the City light rail.
