My wife and I have been N Scale modelers for several years. We have found the most fun in taking kits or 3D model buildings and turning them into completed scenes. As we have a huge stick of pre-built, we decided to share these at a much reduced cost considering the time and effort put into each. Many of our models even include interior or exterior lights that runs on simple 12vdc (you can test with a 9v battery) not requiring you to add resistors. Enjoy !!
