This kit is perfect for beginner, intermediate and advanced models alike! The inside is open and really lends itself to adding a nice interior. I added scratch-built and retail parts I got here on Hobbylinc. The pictures show what I did to the inside. The kit goes together really well but you need to take your time and use some type of guide (I used a miter box) to square the walls. If you are going to use acrylic paint, be sure to prime the wood with an enamel primer or the wood will warp. The door rail is not included but you can easily make it with some of the scrap wood left over in the kit. This would be a great kit to get if you never made a wooden one but always wanted to try. It is going to make a nice addition to our Annual Christmas Train Layout this year.
