First off, my apologies to those of you who have tacked these questions at this same time every year when another newbie finds these forums. My only experience with model trains has been the HO scale stuff from Markline that my father got into the late 70's and early 1980's. While he had aspirations of buying major layouts, I dont believe they ever went anywhere. Now, with kids of my own, its fallen on my shoulders to consider doing the Christmas Villiage. I can tell you up front, I wont be dedicating myself to this as another full time hobby, but I do have a passing interest in setting up an interesting yet simple Xmas Villiage that gets added to over time, starting with a train. It looks like if I want to go the more simple route, the 0-scale villiages that abound are nicely mated to O-scale or On30 scale trains. Is this correct? If so this means I can buy and use HO scale track for use with a train that is On30 scale. Is that correct as well? O is a larger scale train running on narrower track (HO)...uh..right? I was going to do something in a smaller scale to make 12" radius turns (I have some furniture that would be ideal for this but its only 15" deep, but then I learned that most of the villiages out there (Department 56, the Hawthorne stuff) would make those really small trains appear too tiny. Now when I say Xmas Villiage I mean purchasing items (probably not modeling them, painting and detailing them but rather the pre-fab ceramic type items) and adding things like plastic trees, and white cotton for snow. Not building mountains, adding forests, bridges and the like...at least, thats how I'm going into this. I know modeling can be an addiction (having done some 1/64 scale WW2 stuff back in the 80's). Bachmann looks like the sets to buy, and if I want to get really pricy I can go with Hawthorne's "licensed trains" that appear to be modified Bachmann sets? Is that about right? Are there other things I should be considering that I'm not? Is On30 big enough to be under a tree with some village components and not be "lost".....and whats the tightest radius I can do with on30 (HO?) track? I've been thinking of a bachmann starter xmas set and maybe adding to it with other ON30 cars (perhaps repainted by me in an xmas theme) over the years to go with the Hawthrone and Dept56 style villages and diorama accessories. Comments appreciated, and thanks for your patience.
