Hank has a question for readers:

“This is my first attempt, I want to do a module in N scale. What I’ve got is a roundhouse with 6 compartments and a non powered turn table. I am open to suggestions on how to plan and then start putting this together. Please keep it as simple as possible, do not send me any complicated diagrams for I’ll give up and my train collection will be just that a collection to show and tell. I would like a main line to the round table and then to the roundhouse.”

Hank there is a very good manual on building modules called “Confessions of a Mobile Layout Builder” available as a bonus here http://www.modelrailwayscenery.org/model-railroad-scenery.html
