Been many years since I did anything with model trains. In fact it has been about 30 years. I picked up another hobby which some time I will tell you about. But lets just say I have the nose of an airplane in my basement..lol So coming back I though I would do some research and man have things changed. I have a lot of catching up to do before I start on the build of my HO shelf layout. Nice to have found this place and I look forward to learning.
