This was always my first preference actually, but the problem is they just did a big expansion of this yard and it'd be a heck of a lot of money wasted.There's also an option there for the Mayne railyards which I hadn't seen before.
I think distance to CBD is important, although Hamilton isn't too far away in my view.The ratings are pretty subjective and doesn't seem to take nto account the distance from the CBD. That said, the London Olympic Stadium was a fair distance out of the city (although their public transport system is better than ours).
