For me...
My very first train set was a Lionel with a small oval of track. Right then and there, my bias was set for the concept of continuous running. For years, It never occurred to me that there was an option. I bought layout books, like 101 Track plans, and most of the layouts are continuous running except very small and very large layouts.
The very small shelf layouts seemed to be offered to folks who had very limited space, and I always wondered what one would actually do with a layout that small. The very large layouts were where one found the Point to Point configurations. They required huge spaces and a budget the size of the Union Pacific Railroad's to actually construct. The middle ground layouts always seemed to be a continuous loop of some sort. Maybe they were not, but I sub-consciously skipped right over them. I can't really be sure. Of course, I wanted sidings, but only because one needs a place to park some freight cars so it looks nice.
Watching the trains run is easy. The concept of having an actual operating session seemed very tedious.
Yet, it seems to me at this point in my involvement in the hobby, that my tastes are evolving from a focus on continuous running to the trains actually doing some work. The trains must have some purpose in order for the entire exercise to make some sense. I clearly understand the purposes of passing and staging tracks However, even though i now clearly understand the concept and value of a point to point layout, I can't imagine actually building one for two reasons:
1. My bias set in my early years in the hobby is so strong towards continuous running. It would be like changing from being right handed to left handed.
2. Demonstrating the layout to folks who are not in the hobby, or to children, is much easier to do with a continuous loop (at least for me). The trains run while I talk, without requiring any attention at all from me.
And in my early days in the hobby, there was no point in even trying to talk to me about modeling a specific era. If I liked a locomotive, I could find a rationale for getting it and putting it on my layout My fertile imagination could make just about anything work. Even now, I find the concept of modeling a specific era to constraining. At least I have now limited myself to the family of railroads that were the ancestors of modern day CSX. That's progress, at least.
Now, the question is, is my development in the hobby typical? And, if one evolves and goes through stages in the hobby, is it really possible or even desirable to skip stages? I can tell you this: my current layout is my third of my lifetime. When I first started building each layout, I really believed I would be totally satisfied with it, and it would be my last. I've been working on my current layout for a year, and I already am realizing that it has issues that can probably not be resolved without a taking the chainsaw to it. But on paper, it looked perfect.
So ignorance is bliss. As a beginner, I began my model railroading adventure in utter bliss. My challenges have added up as I have gained experience and knowledge. The MRH website has contributed mightily. My advice to any beginner would be to not glue anything down. All track should be easy to pick up so you can start over. Don't invest time and money into scenery until you fall in love with your track plan. But, that's just me. Experiences may, and probably will, vary
