I stumbled onto this delightful invention (and the pleasant, highly-talented fellow responsible for it) researching a high-end component for work.* For years, I've claimed the only thing that kept me from having a model train layout was the lack of space; I've looked with interest at some of the very small-scale setups, especially the "mountainside" ones that are more vertical than horizontal (much too tricky for a beginner, I'm told, as it's a delicate balancing act between grade and traction) . Well, those excuses have been shot right down if I could be running my own rail line on the living room ceiling.
(It just occurred to me that some fan of The Fifth Element is probably planning a vertical building-side passenger express already. Can't find an example online but it would be very fine).
I'm going to add this to the "Live Steam" category; sure, the models are (mostly) electric but many of the originals were not.
P.S.: Speaking of train layouts in interesting places...! Wow.
