Amazed it has taken this long to provide a railway station at a major shopping complex.
Is Victoria still asleep at the wheel?
Ah. Well, it's not that simple. The people who own Southland (and Chadstone) have for a long time been quite hostile to the idea of there being a railway station at their complexes. So they have been able to stymie it any time it came up as an option.
Westfield (owners of Southland) opened a London site a few years ago, built directly adjacent to a rail line. However, they tried very hard NOT to have it connected to a station - it basically took the local council saying if it didn't have station access, they wouldn't be able to build, before they gave in.
Gandel (owner of Chadstone) was always steadfastly opposed to there being a railway station under Chadstone though, and his pockets are very deep.
