Glad I could help you Arnold!
As for the obstacles, that's another story. I know of many model railroaders, including the late John Allen, who converted structural obstacles into scenic features. Maybe those troublesome horizontal pipes could be incorporated into a petroleum facility or some sort of industry.
I have a customer in San Francisco who, instead of concealing old pipes and conduits in his offices, painted them bright colors creating a colorful ambiance rather then a drab industrial look.
