Model train lovers have the perfect hobby because it truly is a whole picture understanding, where the imagination and innovative problem solving pieces must perform in tandem with the more meticulous and logical thinking pieces.
This imagination starts with the feeling that you really are the engineer as you watch the train run your layout. You will find you dream up a tale and make believe what is going on inthe homes in the village you built to go with your model train arrangement. The set up will continually be changing, as your imagination takes the tale in different directions. As you come up with new ideas and plans for a new train layout for the town, your creative juices and problem solving will be in full force.
The technical piece of things can be likewise fulfilling. Train maintenance and mending lets you break stuff apart and put them back together again. It is detail work with a large satisfaction feature. Using a wire brush to clean the tracks and dealing with those connector pieces the old train O scale sets have for linking the tracks may drive you over the edge, but you are thinking up new layouts as you perform. It really is the entire story.
I recently created a trains o scale hobby site. Check it out.
