Candids around the previous and new layout, before and after:
I found the Atlas bridges do not like to be touched or handled so I made a dropped tray with grip ovals and centering blocks and glued in track pieces on each end so the bridge it's self is only for decoration.
The Lionel lift bridge and HD stool make ease of access up stream.
Pond bottom made by cutting out three elevation lines on a 45 degree angle with a jig saw then reverse stacking them below the valley floor.
The brass dowels position the bridge and supply wireless power to the bridge rails.
The dual magnets hold the bridge in place.
The micro switch below controls power to each of the approach tracks.
