Roger, Bobby and Lenny - thank you for your input. This will be in our reception area. No workers in this area but a large window for those who pass by our space.
I'm thinking about two small loops. One with a (Williams?) Engine, two cars and caboose and one with either a K-Line Porter or perhaps the K-Line Polar Bear "speeder". The noise is not a problem as no one sits in that area.
Security is not an issue and I just want to have some fun this Christmas season at work. Once again thanks for the input.
Paul
