It boils down to the creation of that perfect world. It may be in the assembling of a few choice train sets for display, a single train running around the tree or a complete layout furnished with every accessory imaginable. Our minds eye dreams the scenario then we put forth control to achieve that dream creation
To what degree and in what direction we prefer to take our creativity are so varied that we each end up creating unique perfect worlds. JLC knew the importance of creativity in a child's world and how his trains instilled a sense of control over a miniature empire. All the attributes found in the creation of an art form.
