In the mid/late 70's I got into HO model railroading. I had a 4x8 table with a simple layout which kept me (sometime) out of mischief as a teen. Unfortunately all that equipment is gone. But now with two grandsons, 2 & 10 months, and seeing some neat Christmas displays online, I'm getting the fever again. I don't have a lot of room. But I'm considering one of three directions. One, a small display incorporating our tree. I'm guessing N for this. Two, a larger one I could use outdoors in a Christmas yard display. Or around our outdoor bar area around the pool during the season. Three, a small HO or N I can build in a room in our church for the K-5 ages & use as enticement for our SS program. I'm pretty decent with woodworking. And have been in the instrumentation field in the chemical industry for close to 30 years so I'm familiar with electronics / pneumatics / some programming. I'm searching this site for these topics. But I'd appreciate any ideas, links, books, DVD, etc anyone can recommend. Thanks folks!!!
