The McComas and Tuoy 6 Video set had many things in it that significantly impacted me regarding model railroading, all of which were extremely positive.
One of the featured layouts was that of an elderly retired physician, who had a beautiful and very large layout that included a steam boat that moved along a river, and who had lost his wife not long ago. I don't remember this retired physician's name, but I bet some of you folks do. Anyway, what I found most memorable was what he said about getting together with his train friends who helped him build his layout after he suffered such as devastating loss. What he said was that his get togethers with his friends to work on his layout was good therapy for him.
I find that whatever I do on my model railroad, no matter how much or how little, is good therapy for me. If I have some big problem, my model railroad is my man cave, my sanctuary, where I can retreat, not talk, and mull things over while running a train, tinkering with the scenery, applying a little oil or lube to a squeaky engine or train car, etc.
I have a few more things to share about how my trains serve as good therapy for me, but before I do, I would love to hear from you folks about how your trains are good therapy for you. Arnold
