My dad spent many years working in the display industry and is a very good 3-D artist. Unfortunately, I did not inherit any of his skill. This is a 3/4 scale train that he built in his backyard in his spare time. I find it quite amazing. He just used pieces of things that he had lying around. It has working lights, a bell, a whistle and you can crawl around inside the boiler. He made it as a little clubhouse for the grand kids. I have heard that he has also built a caboose to go with it but I haven't seen it yet.
