I was designing an N scale layout that would fit in a small room of my house. I first designed it using RT in the HO mode, just doubling the dimentions. Then you guys told me about the N scale library. I downloaded it and tried to lay out my former design and Surprise! nothing fit! Now I am redoing the entire thing and have run into a problem with an industrial area. Do you set out the industries and then run track to them, or do you lay out your track and then fit industries into it? It went fairly easily the first time, but now that I am doing it "right" nothing seems to fit. Suggestions?
