Perhaps this would work to preserve access for maintenance and detailing, yet reach the Nuc Plant on the elevated NS. The track beneath the monitor could be a shelf disguised as a long bridge. I can't use the NS as an interchange track above the yard because of the slope. But I can still receive and depart trains for the NS that head up the grade. My RR would need the NS dispatcher to clear access to service Hillsdale and the Nuc Plant, and NS would need operating rights to bring trains in and out of Bailey Yard.
