I've noticed that in a lot of railroad musuems and some countries, that while the standard AAR Knuckle coupler isn't directly used, they use a similar varient, simply because with so many units being sold, and resold iinternationally, it's become the standard. I do not know what type of knuckle that was, I checked wikipedia's entry on coupling and couldn't find it. Looks like what the Queensland Railroad Tilt Train uses but I can't confirm that either. And what I want to know is, how did they crash into each other?
