I was very active in N Scale model railroading many years ago, but have been out of it for about 18 years now. (mostly because of the kids, who are now grown)
I am planning a new N Scale layout that combines Cajon, Tehachapi, and Donner Passes but I am finding that the hobby has changed a lot since I have been gone.
A lot to learn! I feel like I am starting over again.
