Ex-Southern 385 Being Hoisted
If I remember right, it's a magnet system that goes under the layout and the cars have little magnets under their noses that pull them along. That HUGE German layout that everybody bashes all the time has it installed. (Wunderland or something like that??) They show it on their web site.

I had no idea that something like this existed, but Faller of Germany has developed a revolutionary system for automating vehicles in HO scale. It's the first time I've seen the trains take a back seat to the vehicles on a layout. My German is a little rusty, so if anyone out there can translate some of the finer points, feel free. It's a shame they have no models of US prototypes.
