Ben,
I hope that someday there is a new layout with whatever scenery can be salvaged from the old. That will leave people with a fond memory of what was in Paterson.
However the NJHR goes forward, I don't think it's necessary to create a new railroad that's quite as elaborate. People will still come to enjoy the layout, the food, and the hospitality.
Best wishes and let us know how it's going.
