Hi-I'm a total N scale newbie, and pretty much a model train newbie, we have done one lay out-HO scale, for a friends child--that was so much fun I asked Santa for my own train, and got it. Its a N scale bachmann Iron Duke. My husband bought it for me and now I need to figure out what kind of layout I want-- I would like to do a ZOO layout with the train being a tour train--just not sure if I can find animals that small. What do you think is it possible?? Has anyone ever tried before??
