I try to enjoy the (budding) layout a little at a time. Upon reflection, I may be like you in that having others enjoy the trains are a larger factor than I had thought. I also have had to re-vision what I am doing; dropping, for instance, from 16-20 car trains to 6 car trains, and a more modular style layout. I understand that refocusing in that way would be silly for you, in light of what you have already completed.
