Here is a 2 rail scale model that you may enjoy.
Attended the Large Scale Train Show at York on Friday. Took my buddy over to the Charles Ro booth to show him their BigBoy and stumbled on this:
It's a Gauge 1 Pacific Steam engine manufactured by a Swiss company called Fulgurex. Their models in N, O and G are handmade in brass in limited quantities. It's a Deutsch Reishbahn (DR 18) cab#201. It is very similar to a model made by MTH a couple of years ago. It was in mint condition with a $6,000.00 asking price (make an offer). A follow up to a company called Reynaulds Trains which sells only European models said this loco probably sold for $10,000 .
He asked me what I paid for it and said that I made a "steal" (it's about time). It comes with lights only and runs under DC power.
I made a couple of counter offers and we agree upon a price. This model was shipped yesterday to an installer for the installation of DCC, synchronized smoke timed with the drivers and I hope smoke. Much to my amazement is the fact that this loco is under steam today and ran in 2014 in Germany.
Here is a you tube video showing it in action; watch in HD and enjoy.
