Welcome to the Forum!
I started out as an O gauge train collector too!
It sounds like me you have been bitten by the steam bug!
You will find so many wonderful and helpful Forum members here and lifetimes of experiences and knowledge.
The Karsten Gintschel Tornado is a very unique model to start your collection.
BTW: Mr. Gintschel also made a turbine for the Jensen Model 95G. You can see it and read about it on Jensen's website: http://www.jensensteamengines.com/commercial/c95g.htm
Good luck with this new chapter in your "steam" journey.
