Yes, that is my thinking too. For me it's the buildings. There are some buildings that stand out and are close to the tracks...I call them "landmark buildings". Unfortunately, some of those buildings are difficult models to make. The idea for this layout was to get the feeling you are traveling back in time to the 1950's, there is limited amount of default items for this task. The track is another sticking point. There is no 3rd rail track out there like the Laurel Line's 3rd rail track. In my eyes it simply needs to be made for the layout to be complete.
My route that I am working on is every bit of 60 miles long, and what really complicates it is that it involves the old P&LE line (now CSX) on one side of the river and the PennsyCentral (NS) line on the other side, which effectively doubles a good portion of the trackage. I can safely say that it will likely
never be finished (especially since I don't believe I have placed as much as a single tree in two months) because I've been working on reskins so much lately. It doesn't discourage me, though, because I am making the route for
me to enjoy. If I ever finish it and get to release it for others to enjoy, well that would be nice too. Just remember that this is something for
you and it is for you to enjoy. Don't worry about finishing it for everyone else. If it takes you twenty years, we'll be here to enjoy it (or at least someone will).
I agree that there are certain specific buildings that you will
need to have. Focus on those. I really wanted a pair of bridges, Ben made incredible ones for me, and the rest I can work around. When I deed something else specific, I will ask for it, but for the most part, I can get by. If I need a Sheetz station I can make one (but fortunately, Ed saved me the trouble). If it isn't available, a BP will do just as well. A gas station is a gas station. You are doing a great job. Keep your chin up.
