Hi I am a new member and I have bent ring to scratch build everything I can. I am having a little trouble getting started. I don’t know where to get dimensions of buildings I do have one book that is good it is from model railroader from the early 60’s but I am looking for others. I am also looking for the sizes of styrene to use, nothing is labeled n scale. Not sure what I should be using. So I need a beginners guide to modeling n scale. Does anyone know a book or website?
