Why MELBOURNE AIRPORT has no trainline

Melbourne's Airport rail link just had some bad news. What's happening to the project, when will we get a rail link, and what's been completed? I visit the main construction sites to see what's been completed in terms of new stations, new lines, and a new link to the International Airport.
