Recently retired and wanting to get into N scale. I've read and watched so many articles and videos I'm beginning to blubber to myself. Could use some awesome advice. The plan is to use 3-4x4 modules on half inch plywood. Don't want to buy a set but start out piece meal. Really need advice on track,turnouts and locomotives. I believe I'm going to stay with 1960"s theme in Texas. More industrial than passenger. Thanks so much for any help.
