Queensland invasion

I got a shock today during my train ride into work. I looked outside the window to see a QR (Queensland Railways) freight train travelling towards us in the opposite direction! I know we were going north, but not that far north. Apparently the difference between NSW's standard gauge tracks and Queensland's narrow gauge is not enough to keep the Queenslanders away. I knew that there was a valid reason for the rail gauge mess that is Australia, but it looks like the Queenslanders circumvented it by buying old Victorian Railways stock and forming QRNational. Now I am haunted by my past.
