Mister Buffett has a toy train layout at his home. He was on Face Book a few months ago sitting by his platform singing "I been working on the Rail Road" and strumming on a ukulele.
The layout you see above is a mock up of the Burlington RR, that he owns. He brings it out when he has a corporate get together as a public relations tool. I read about it in ether CTT, or O-Gauge magazine.
Gee, do you think he can afford such an expensive hobby?
