I stumbled onto this while looking at some new diecast 1/50 stuff being announced. Look at the very bottom of this page. Miniature Construction World - Toyfair 2010 An N Scale Bucyrus 495HR. Wow... I can only imagine how much that will cost.
Actually, I thought it would be more than that. That would certainly look sweet in a coal mine scene. And you'd probably be the only kid on the block to have one.
I’m not even sure it would fit on my layout but what a great centerpiece for an N-Track module. It says it will have working wenches. I guess they’ll serve food and beer.
