The Station Formerly Known As

I quite like the new styling of Spencer Street Station, I think the renovations were long overdue and the whole station is much easier to navigate. What baffles me is the name change. "Southern Cross Station"? I'm pretty sure having the street name is far less confusing for everyone and allows us all a little more alliteration in our lives. Still, what's more puzzling that original change is the fact that they can't seem to ditch the original name! See, it turns out that all the signs read "Southern Cross formerly Spencer Street". So what was the point of the name change?

I predict that within 10 years time it will be renamed "The Station", only to realise that's idiotic and change back to "Spencer Street".
